EXECUTIVE SUMMARY
Printed documents are the primary mechanism for distributing technical knowledge — planting guides, structural tables, drug dosages — to communities that will lose digital access as devices fail. NZ’s printing supply stocks are finite and irreplaceable; every page printed at default settings wastes toner and paper that could have produced additional copies of critical documents. This document provides the operational specifications for print optimization: which settings to change, which fonts to select, how to format documents for maximum density without sacrificing legibility, and how to match print quality to document purpose.
The combined effect of the measures described here – toner-save mode, efficient font selection, duplex printing, reduced margins, and purpose-appropriate formatting – can reduce toner consumption by 40–60% and paper consumption by 50–70% compared to default single-sided printing at standard settings.1 Applied across the full Recovery Library production run, this effectively doubles or triples the number of document sets producible from the national stock.
These are not theoretical recommendations. Every measure described here uses settings already available on the printers and copiers in NZ’s installed fleet. Implementation requires only changed defaults and operator awareness – no new equipment, no new materials, no new skills.
Contents
RECOMMENDED ACTIONS
Immediate (Weeks 1–4)
- Issue default print settings directive to all government departments, hospitals, schools, and institutions with active printers. Toner-save mode on. Duplex on. Margins reduced. (Low effort, immediate effect.)
- Distribute this document as the operational reference for all printing personnel. (Prerequisite for consistent implementation.)
Phase 1 (Months 1–6)
- Establish document tier classifications (Section 3) and assign every printing job to a tier before production. (Moderate effort – requires printing authority coordination, Doc #29.)
- Standardise Recovery Library document templates to the specifications in Section 2. (Low effort – one-time setup per production site.)
- Begin lamination of Tier 1 field cards using available laminating pouches and equipment. (Low effort where equipment exists.)
- Consolidate printer fleet around models with best toner efficiency and duplex capability (Doc #5, Section 8). (Moderate effort – fleet rationalisation.)
Ongoing
- Monitor toner consumption rates against production targets. Adjust optimization level if stocks deplete faster or slower than projected. (Standard operational practice.)
- Inspect printed output quality periodically – toner-save mode on degraded drums can produce unacceptably faint output that wastes paper through reprinting. (Quality control.)
ECONOMIC JUSTIFICATION
Person-years of labour
A print optimization program requires three categories of skilled staff. The estimates below are for a national program producing approximately 1,000 complete Recovery Library sets as an initial run.
| Role | Year 1 | Ongoing (per year) | Notes |
|---|---|---|---|
| Print technicians (fleet setup, settings standardisation, quality control) | 8–15 | 4–8 | One technician per major regional printing site; requires familiarity with copier/printer operation and maintenance |
| Paper conservators (storage management, condition assessment, stock rotation) | 3–6 | 2–4 | May be partially filled by library or archival staff with some retraining |
| Logistics and distribution staff (sorting, packing, inventory, transport coordination) | 10–20 | 6–12 | Largely unskilled or semi-skilled; significant share of total labour |
| Training coordinators (producing and distributing operator guidance) | 2–4 | 1–2 | Train-the-trainer model; one-time intensive, then ongoing periodic |
| Total | ~23–45 | ~13–26 |
These person-years are modest relative to the value delivered. Print technician skills are widely distributed in NZ’s existing workforce — every organisation that operates a reprographics room or managed print service has staff with relevant experience. Paper conservators are scarcer, but many of the required storage practices (controlled temperature, humidity, pest exclusion) are transferable from related roles in warehousing, archival management, and food storage.
Optimized versus unoptimized use of finite stocks
Doc #5 estimates national toner stock at 80,000–350,000 cartridges at an average yield of 5,000–15,000 pages per cartridge — a range of 400 million to 5.25 billion pages at default settings. The figures below illustrate the production implications at several stock scenarios and optimisation levels.
| Stock scenario | Unoptimized output (Tier 1 only) | Tier 2 optimized output (~2× factor) | Tier 3 optimized output (~2.5× factor) |
|---|---|---|---|
| Low (400 million pages) | ~500 complete library sets (at ~800,000 pages/set) | ~1,000 sets | ~1,250 sets |
| Mid (1.5 billion pages) | ~1,875 sets | ~3,750 sets | ~4,688 sets |
| High (5.25 billion pages) | ~6,500 sets | ~13,000 sets | ~16,250 sets |
Assumptions: 800,000 pages per complete Recovery Library set at 1-up, single-sided default settings; library set count scales proportionally with optimization factor. These are illustrative estimates — actual page count per set and actual optimization factor will vary by document mix and production practices.
The multiplication effect is decisive. At the mid-stock scenario, Tier 2 optimization doubles the number of communities that can receive a complete set — from roughly 1,875 to 3,750. At the low-stock scenario, it may be the difference between covering all NZ regions and covering only the most populous. Every additional complete set distributed to a remote community represents a qualitative difference in recovery capability: a set in Northland is not substitutable for a set in Southland.
Breakeven timeline
The program requires approximately 23–45 person-years of labour in Year 1. The cost of establishing optimized print settings across all production sites — mostly time spent on fleet assessment, template standardisation, and operator training — is largely front-loaded. By Month 3, the optimization framework should be operational at major regional sites; by Month 6, at smaller sites.
Against this one-time investment, the benefit begins immediately on the first print job run under optimized settings. There is no deferred breakeven in the usual sense: the first page printed under Tier 2 settings uses 40–50% less toner than the same page printed at default. The program pays for itself on the first production run, not after years of operation.
A more meaningful breakeven question is: does the cost of the program justify the staff time diverted from other recovery tasks? At 23–45 person-years Year 1, against an effective doubling of library distribution capacity, the answer is clearly yes. The opportunity cost of not running this program is the difference between the optimized and unoptimized distribution columns in the table above — hundreds of additional complete library sets that never reach communities.
Opportunity cost
Print technicians and logistics staff required for this program are not highly specialised relative to other Phase 1 recovery priorities. The skills overlap significantly with roles that will exist regardless of whether an optimization program is run — printers need to be operated, paper needs to be stored, and output needs to be distributed in either scenario. The incremental cost of the optimization program is the additional time spent on settings standardisation, template production, and training — not the full cost of running a print operation at all.
The more meaningful opportunity cost is paper conservator time, which is genuinely scarce. Staff with archival or storage expertise will be in demand across multiple recovery priorities (documentary preservation, medical records management, heritage skills preservation). This program should not monopolise their time: the core paper storage requirements (Section 5) can be delegated to logistics staff following written guidance, with conservator input limited to initial site assessments and periodic condition reviews.
1. TONER CONSERVATION
1.1 Toner-save mode
Most laser printers and copiers manufactured since approximately 2010 include a reduced-density print mode – called EconoMode (HP), Toner Save (Brother, Samsung), Economy (Ricoh, Canon), or similar. This mode reduces toner deposition per page by approximately 30–50%, producing lighter but legible output for text documents.2
How it works: The printer reduces the charge applied to the photoconductor drum, resulting in less toner transferred to the page. Text appears grey rather than solid black. Fine lines and small text become thinner. Solid fills become visibly lighter.
When to use it: All Tier 2 and Tier 3 documents (Section 3). All internal, administrative, and working documents. All draft copies.
When not to use it: Tier 1 documents – navigation tables, medical dosing references, engineering specifications, and any document where a faded digit could cause a consequential error. Field cards intended for lamination. Documents that will be photocopied further (each photocopy generation loses contrast; starting from toner-save compounds the loss).
Setting location: On most HP LaserJet models, EconoMode is found under Printer Properties > Paper/Quality > Print Quality or EconoMode checkbox. On Ricoh MFCs, it is typically under Printer Features > Toner Saving or Economy Color. On Brother printers, it is under Print Settings > Toner Save Mode. The setting can usually be applied as a system default by an administrator, which is preferable to relying on individual users.3
1.2 Font selection
Fonts differ in toner consumption because their letterforms vary in stroke width, counter size, and overall coverage area. At the same point size, a thin-stroked font like Garamond deposits less toner per character than a wide-stroked font like Arial.
Measured differences: A widely cited analysis found that Century Gothic consumed approximately 30% less toner than Arial at equivalent point sizes. Garamond consumed approximately 24% less. Times New Roman consumed approximately 27% less.4 These figures are approximate and vary with specific text content, rendering engine, and printer resolution, but the direction is consistent: serif fonts and light-weight sans-serif fonts use meaningfully less toner.
Recommended fonts for Recovery Library production:
| Application | Font | Size | Rationale |
|---|---|---|---|
| Prose body text | Garamond | 10.5–11 pt | Low toner; excellent readability; widely available on NZ systems |
| Reference tables, data | Garamond or Calibri Light | 8–9 pt | Compact; readable at small sizes with adequate leading |
| Headings | Garamond Bold or Calibri | 12–16 pt | Consistent with body; minimal toner increase |
| Field cards | Arial or Calibri | 11–12 pt | Heavier stroke for durability under wear; readability at arm’s length |
| Draft/internal | Garamond | 10 pt | Maximum density at readable minimum |
Fonts to avoid for production printing: Arial (approximately 30% more toner than Garamond at equivalent size), Verdana (wide letter spacing compounds toner cost), Impact and other display faces (heavy strokes, high coverage), any decorative or script fonts.
Te reo Māori character support: Te reo Māori uses macrons (tohutō) to mark long vowels: ā, ē, ī, ō, ū (and their capitals Ā, Ē, Ī, Ō, Ū). Macrons are not decorative — they are phonemically significant. A word spelled with a macron and the same word without one may be different words with different meanings. The production font must include full Unicode support for macronised vowels. EB Garamond (an open-source variant widely available under the SIL Open Font License) supports these characters via the Unicode Latin Extended-A block.5 Confirm character support before locking in a production font — some older or narrowly licensed Garamond versions do not include all precomposed macron characters. All source files must be UTF-8 encoded; Windows systems defaulting to Windows-1252 encoding will silently corrupt macrons. When generating print-ready PDFs, embed fonts fully rather than subsetting — font subsetting that excludes macronised vowels will produce gaps or substitution characters in te reo Māori passages.
Macron legibility at small sizes: Macrons reduce the effective x-height of characters slightly. At very small sizes (7–8 pt, used for footnotes and reference tables), macrons may become difficult to distinguish. Bilingual footnotes and table entries with te reo Māori content should be held to 8 pt minimum, not 7 pt. When photocopying te reo Māori documents in toner-save mode or on degraded drums, macrons may become indistinct — use standard (not toner-save) print quality for master copies of te reo Māori documents that will be used as photocopy originals.
Practical check: Before finalising any production template that includes te reo Māori text, print a test page containing the macronised vowel set (ā ē ī ō ū Ā Ē Ī Ō Ū) at the intended body font and size on the intended printer in the intended mode. Confirm macrons are clearly visible. If they are not, the template or the printer settings require adjustment before production begins.
Practical note: Font selection saves toner only if applied consistently across production. Establishing Garamond 10.5 pt (EB Garamond for te reo Māori compatibility) as the standard body font for all Recovery Library documents and locking it into templates prevents per-document variation and simplifies production.
1.3 Grayscale and colour management
Colour laser toner (cyan, magenta, yellow) is present in NZ stocks in much smaller quantities than black toner, because NZ’s installed fleet is predominantly monochrome for office use.6 Colour toner should be reserved exclusively for documents where colour conveys information that cannot be conveyed in greyscale: medical imaging references, colour-coded maps, botanical and zoological identification guides, wiring diagrams with colour-coded conductors.
Default rule: All text documents print in black only, even on colour-capable machines. Colour-capable machines should have their default set to “Black and White” or “Greyscale” to prevent accidental colour printing. Colour jobs require explicit authorisation from the printing authority.
1.4 Print darkness settings
Many printers allow adjustment of overall print darkness independently of toner-save mode. On a scale of 1–5 (common on HP models), reducing from the default of 3 to 2 saves approximately 10–20% additional toner with minimal legibility impact for text.7 Combined with toner-save mode and efficient font, this provides cumulative savings.
Caution: Reducing darkness below 2 on most printers produces output that is too faint for comfortable reading and risks waste through reprinting. The optimal setting should be tested on each production printer and documented for operators.
2. PAPER CONSERVATION
2.1 Duplex printing
Printing on both sides of each sheet is the single most effective paper conservation measure – it halves paper consumption with no loss of content quality. All Recovery Library production must use duplex printing.
Fleet capability: Most commercial MFCs (Ricoh, Canon, Fuji Film, Konica Minolta) and many desktop laser printers (HP LaserJet Pro series, Brother HL series) manufactured after approximately 2010 include automatic duplex units.8 Printers without automatic duplex can be manually duplexed (print odd pages, flip the stack, print even pages), though this is slower and more error-prone.
Paper weight consideration: Duplex printing on lightweight paper (below 70 g/m2) produces visible show-through – text from the reverse side is visible through the sheet, reducing readability. Standard 80 g/m2 office paper handles duplex well. If NZ stocks include 70 g/m2 paper, reserve it for single-sided printing of reference tables and data where show-through would impair usability; use 80 g/m2 stock for duplex production.9
2.2 Margin reduction
Default margins on most printing software and copiers are 2.54 cm (1 inch) on all sides – inherited from typewriter conventions and far wider than necessary for bound documents.
Recommended margins for Recovery Library production:
| Document type | Top/bottom | Left (binding edge) | Right | Printable area gain |
|---|---|---|---|---|
| Standard bound documents | 1.5 cm | 2.0 cm (binding allowance) | 1.5 cm | ~20–25% vs. default |
| Reference tables | 1.2 cm | 1.8 cm | 1.2 cm | ~30% vs. default |
| Field cards (laminated) | 0.8 cm | 0.8 cm | 0.8 cm | Maximum content area |
Hardware limit: Most laser printers have a non-printable margin of 4–6 mm on each edge.10 Setting margins below this threshold results in clipped content. Test the actual printable area on each production machine before finalising templates.
2.3 Multi-up printing (N-up)
Printing multiple logical pages per physical page reduces paper consumption proportionally:
- 2-up: Two pages per sheet. Reduces paper by 50%. Each page is approximately A5 size. Readable for reference tables, data, and text at 8–9 pt. Suitable for backup copies and reference archives.
- 4-up: Four pages per sheet. Reduces paper by 75%. Each page is approximately A6 size. Marginal readability – suitable only for archival copies, personal reference, or material with large original formatting (e.g., full-page tables printed at 4-up retain reasonable legibility).
- Booklet printing: Imposes pages in signature order for folding and saddle-stitching into booklets. Produces compact, professional-looking bound documents. Many printer drivers and copier panels support this natively.
Recommendation: Standard Recovery Library production should use normal (1-up) duplex printing for readability. 2-up duplex should be used for secondary distribution copies and reference table supplements. 4-up should be reserved for personal-use copies and archival backups.
2.4 Font size optimization
The minimum readable font size depends on the reader’s visual acuity, lighting conditions, and the intended use:
| Context | Minimum size | Recommended size | Notes |
|---|---|---|---|
| Extended reading (prose, instructions) | 9 pt | 10.5–11 pt | Smaller sizes cause eye strain; readers may be working in poor light |
| Reference tables (occasional lookup) | 7 pt | 8–9 pt | Brief consultation; reader knows what they are looking for |
| Field cards (outdoor, gloved hands) | 10 pt | 11–12 pt | Must be readable at arm’s length in variable light |
| Headings and labels | 12 pt | 12–16 pt | Scanning and navigation |
| Footnotes | 7 pt | 8 pt | Consulted only when needed |
Trade-off: Reducing body text from 11 pt to 10 pt increases content per page by approximately 15–20% (through additional lines per page), reducing total page count proportionally. But readability under stress, poor light, or for readers with impaired vision (common in older adults who may be key knowledge holders) declines. For documents intended for field use or extended study, err toward larger sizes. For reference tables and data, smaller sizes are acceptable.
2.5 Bilingual layout (English / te reo Māori)
The Recovery Library is a bilingual resource. Te reo Māori is an official language of NZ and a living language spoken by the communities this library serves. Documents that include both English and te reo Māori text face layout decisions that affect toner and paper consumption as well as readability.
| Format | Description | Best use | Space cost |
|---|---|---|---|
| Side-by-side columns | English left column, te reo Māori right column | Short parallel passages; glossaries; key terms | ~10–15% more space than single-language (column gutters, reduced line length) |
| Interleaved paragraphs | English paragraph followed by te reo Māori paragraph | Extended prose; narrative content | ~100% more space (full duplication of text body) |
| Bilingual headers only | English body text with section headings in both languages | Technical manuals where te reo Māori is structural rather than throughout | Minimal (~5%) |
| Glossary/terminology appendix | Te reo Māori terms defined and explained in a separate appendix | Documents using significant traditional vocabulary (mahinga kai, rongoā, kaitiakitanga) | Proportional to glossary length |
Recommendation: Full bilingual text (interleaved or side-by-side) should be used only for documents intended for te reo-dominant audiences, when toner budget permits — for example, a rongoā Māori reference card for use in a marae health clinic. For primarily technical documents with occasional te reo Māori terms, bilingual headings and a terminology glossary consume less toner and paper than full parallel text while maintaining accessibility. A gear-cutting specification does not warrant full bilingual text regardless of who contributed to its content.
Column layout specifics: When using side-by-side columns, set column width to approximately 45% of the text block width (leaving 10% for the gutter). At 10.5 pt Garamond in two columns on an A4 page with 1.5 cm margins, each column has approximately 50–55 characters per line — adequate for comfortable reading. Do not reduce below 45 characters per line for prose bilingual text.
3. DOCUMENT QUALITY TIERS
Not every document requires the same print quality. Matching quality to purpose conserves toner and paper for the documents that need them most.
Tier 1 – Full quality
What: Navigation tables (Docs #10–12), medical dosing references (Doc #20), engineering reference tables (Doc #17), chemical safety data (Doc #21), surgical procedure cards, pharmaceutical interaction tables, tide tables, topographic reference sheets.
Why: A misread digit in a drug dosing table or a navigation calculation can cause death. These documents must be printed at full darkness, full resolution, using fonts optimised for clarity rather than toner savings.
Settings: Toner-save OFF. Standard or high print density. Font: clear, well-defined typeface (Calibri, Arial, or Garamond at 10+ pt). Full margins. Printed on the best available paper stock. Consider lamination for field cards. Printed in colour where colour encodes critical information (e.g., hazard classifications, wiring diagrams).
Expected toner consumption: Baseline (no savings applied).
Tier 2 – Standard quality
What: Recovery Library technical guides, policy documents, operational manuals, training materials, agricultural guidance, trade instruction documents, the bulk of the library.
Why: Readability matters – these documents will be studied, taught from, and consulted repeatedly. But a slightly lighter print does not create safety risks.
Settings: Toner-save ON. Print darkness reduced one step below default. Font: Garamond 10.5 pt. Reduced margins (1.5 cm sides, 2.0 cm binding edge). Duplex. Monochrome.
Expected toner saving: 40–50% per page versus Tier 1.
Tier 3 – Draft / economy
What: Internal planning documents, working papers, meeting minutes, drafts for review, administrative correspondence, census forms (which are filled in by hand after printing).
Why: These documents have short useful lives. They will be read once or a few times, annotated, and discarded or archived. Maximising copies per cartridge is the priority.
Settings: Toner-save ON. Print darkness at minimum acceptable level. Font: Garamond 10 pt. Maximum margin reduction. Duplex. 2-up where the document format allows. Monochrome.
Expected toner saving: 55–70% per page versus Tier 1.
Tier classification for specific document types
Several document categories require specific tier assignments regardless of their general classification:
- Rongoā Māori plant identification cards: Plant-based medicine requires accurate species identification. Misidentification of a medicinally useful species for a toxic one can cause death. Botanical identification cards for rongoā species must be printed at Tier 1 quality and laminated where possible, for the same reason that medical dosing cards are Tier 1: a faded image that causes a misidentification has the same risk category as a faded digit in a drug dosing table. Colour printing is justified where colour encodes critical distinguishing information (leaf colour, berry colour, bark markings). See Doc #20, Section 5.1 for the primary rongoā species requiring identification support.
- Safety-critical food preparation instructions: Several traditional food species are toxic without correct preparation — karaka berries require prolonged soaking and cooking to leach karakin; bracken fern root (aruhe) contains ptaquiloside, a carcinogen of concern under heavy consumption. Printed preparation guides for these species are Tier 1 regardless of the document’s overall tier classification: full toner density, larger font for key procedural steps, and explicit visual indication (bold, boxed, or otherwise marked) for safety-critical steps. The format conventions for pharmaceutical dosing cards (Doc #20) provide a useful template.
- Maramataka (Māori lunar calendar) references: Format as tables or calendar grids — compact, durable, suitable for lamination as field cards. Include lunar phase indicators alongside recommended activities. Because maramataka varies by region and iwi, any printed reference must clearly identify the source community and applicable region; generic national maramataka tables that elide regional variation are less useful and may be incorrect for specific locations.
- Traditional navigation reference cards: Star-path information, swell-reading indicators, and bird-behaviour navigation aids should be formatted consistently with Doc #139 (Celestial Navigation) — compact, laminated, waterproof. Star path information should use clear diagrams oriented to the Southern Hemisphere sky. Characters in star names drawn from te reo or traditional Pacific naming conventions must be rendered correctly (with macrons where applicable).
- Harakeke processing guides: Format as workshop reference cards — steps in sequence, illustrated where possible. Tier 2 for general use, Tier 1 for master copies used in training programmes. These guides work best alongside teaching by experienced kairaranga, not as standalone instructions — format for a reader with some contextual knowledge.11
Tier classification responsibility
The National Printing Authority (Doc #5, Section 5.1) or its local delegate assigns every print job to a tier before production begins. The default tier is Tier 2. Tier 1 requires explicit justification (the document contains safety-critical numeric data, will be used in field conditions, or will be photocopied further). Tier 3 is applied to any document with a short expected useful life.
4. PRINTER MAINTENANCE FOR LONGEVITY
Doc #5 (Section 8) covers fleet management in detail. This section addresses the maintenance practices that specifically affect print optimization.
4.1 Drum care
The photoconductor drum is the component whose condition most directly affects print quality. A worn drum produces faded, streaky, or blotchy output – which may cause operators to disable toner-save mode or reprint pages, wasting toner and paper.
Extend drum life by:
- Avoiding unnecessary exposure to light (remove drums only in subdued light; replace immediately)
- Cleaning the drum surface gently with a lint-free cloth if print quality degrades before the rated page count – surface contamination sometimes mimics drum wear12
- Running printers at consistent duty – long idle periods followed by heavy use stress drums more than steady moderate use
- On machines with separate drum units (Ricoh, Konica Minolta, Brother), tracking drum page count independently of toner and replacing only when print quality actually degrades, rather than at manufacturer-recommended intervals which are often conservative
4.2 Fuser maintenance
The fuser melts toner onto the page using heat and pressure. A failing fuser produces smeared, unfused output – again causing waste through reprinting.
Signs of fuser degradation: Toner that rubs off when touched, wrinkled pages, paper jams at the fuser exit, ghost images from previous pages. When these appear, the fuser should be replaced from cannibalized parts stock (Doc #5, Section 8.2) or, for some models, the fuser roller can be resurfaced by a trained technician.
4.3 Cannibalization protocol
When a printer fails beyond economic repair, every usable component should be harvested before the machine is scrapped:
- Drums, fusers, transfer belts, pickup rollers (direct replacement parts)
- Motors, gears, bearings (for fabricating replacement parts for other machines)
- Power supplies and circuit boards (for electronics repair)
- Optics (laser units, mirrors, lenses – fragile but irreplaceable)
- Sheet metal and plastic housings (raw material)
Organisation: Cannibalized parts should be tagged by model compatibility and stored in a central parts depot at each regional printing site. An inventory list mapped to printer models in the active fleet ensures parts are matched to machines that need them.
5. PAPER STOCK MANAGEMENT
5.1 Storage
Paper storage conditions directly determine how long the national paper stock remains usable. See Doc #5 (Section 4.4) for detailed specifications. Summary:
- Temperature: 18–24 degrees C. Avoid temperature cycling (condensation damages paper).
- Humidity: 40–60% relative humidity. NZ’s North Island humidity, particularly in summer, exceeds this range in uncontrolled environments – paper stored in sheds, garages, or shipping containers will degrade.
- Protection: Keep paper sealed in original ream wrappers until use. The moisture barrier in standard ream packaging extends shelf life significantly.13
- Pests: Silverfish and rodents consume paper. Storage areas require pest management.
- Best locations: Climate-controlled buildings: government offices, libraries, school buildings with heating. Avoid ground-floor storage in flood-prone areas.
5.2 Paper type allocation
If the national stock includes multiple paper grades, allocate them by purpose:
| Paper type | Weight | Best use | Avoid |
|---|---|---|---|
| White bond (standard A4, 80 g/m2) | 80 g/m2 | Tier 1 and Tier 2 duplex documents | N/A – primary stock |
| Lightweight copy paper (70 g/m2) | 70 g/m2 | Tier 3 single-sided documents; drafts | Duplex (show-through) |
| Card stock (160–250 g/m2) | 160+ g/m2 | Covers for bound documents; field cards for lamination | High-volume production (jams on many printers) |
| Coloured paper | 80 g/m2 | Section dividers; quick visual coding of document categories | Body text (reduces contrast) |
| Newsprint / lower grades | Variable | Stencil/screen printing in post-toner era; wrapping | Laser printers (dust and fibre shedding damages drums) |
6. BINDING AND PHYSICAL DURABILITY
Printed documents are only useful if they stay together and remain readable over years of handling. Binding method should match expected use.
6.1 Binding methods
Saddle-stitch (stapled spine): Two or three staples through the fold. Suitable for documents up to approximately 60 pages (15 sheets folded). Simple, fast, requires only a long-arm stapler. Adequate for most Recovery Library documents under 60 pages.
Side-staple: Staples through the left margin of stacked sheets. Suitable for any page count up to staple penetration limit (approximately 50–80 sheets depending on stapler). Does not lie flat when open. Functional for reference documents stored on shelves.
Comb or wire binding: Plastic comb binding and wire binding equipment exists in many NZ offices and print shops. Produces documents that lie flat when open – useful for workshop manuals, cooking references, and any document consulted while hands are occupied. Binding supplies (combs, wire spines) are finite but low-consumption.
Hand-stitched (pamphlet or Coptic stitch): Thread-sewn binding using awl, needle, and linen or cotton thread. Produces durable bindings that outlast staples. Requires minimal equipment. NZ produces wool in large quantities and has harakeke (NZ flax) fibre as an alternative thread source; cotton and linen are less abundant domestically but present in existing textile stocks.14 Training time for basic pamphlet stitching: 20–45 minutes depending on the complexity of the stitch pattern and the trainee’s manual dexterity.15 This becomes the primary binding method as staple supplies deplete.
Perfect binding (glued spine): Requires adhesive and a flat clamping jig. Suitable adhesives include PVA glue (produced from polyvinyl acetate, which requires acetic acid and acetylene – dependent on chemical industry development and not available in Phase 1 from local production), hide glue (produced by boiling animal hides, hooves, or bones – NZ’s livestock industry provides ample feedstock, and production requires only heat and water), or starch paste (produced from wheat or potato starch by cooking with water – readily available from NZ agriculture).16 Hide glue and starch paste are the practical options in early phases; PVA depends on industrial chemistry that may not be available until Phase 3 or later. Produces paperback-style books. Suitable for thicker documents. Less durable than stitched binding under heavy use – spines crack with repeated opening, and pages detach under humidity cycling – but faster to produce.
6.2 Covers
Documents intended for repeated use over years should have card stock covers. Where card stock is limited, use doubled standard paper (two sheets glued together) or repurposed lightweight cardboard (cereal boxes, packaging board trimmed to size). Label covers clearly with document number, title, and version.
7. LAMINATION FOR FIELD CARDS
Critical single-sheet or two-sheet references intended for use in workshops, fields, boats, or kitchens should be laminated. Lamination protects against water, grease, dirt, and physical wear.
NZ lamination stocks: Thermal laminating pouches (A4 and A3 sizes) are held in NZ office supply stocks. These are a finite, imported consumable. Allocate lamination only to documents that genuinely need environmental protection:
- Drug dosing quick-reference cards
- Emergency triage protocols
- Botanical identification sheets (edible vs. toxic plants)
- Knot and rigging reference cards (maritime use)
- Chemical hazard identification cards
- Basic first-aid procedure cards
- Engine and generator troubleshooting flowcharts
Alternatives when laminating pouches are exhausted:
- Clear packing tape: Covering both sides of a card with overlapping strips of wide clear packing tape provides moderate water resistance. Tape protection is significantly inferior to thermal lamination: seams between strips admit moisture, adhesive degrades in heat and UV exposure, and tape yellows over 1–2 years reducing contrast. Useful lifespan in field conditions is months rather than the years achievable with thermal pouches. NZ has significant packing tape stocks in warehouse and logistics inventories.
- Wax coating: Dipping or brushing with melted beeswax or paraffin wax provides water resistance. Beeswax is renewable from NZ’s apiculture industry (NZ has approximately 900,000 managed hives); paraffin wax is petroleum-derived and limited to existing stocks (candle supplies, industrial wax) with no domestic production pathway.17 The document becomes noticeably translucent and the wax surface attracts dust and scratches easily – legibility is reduced by approximately 10–20% compared to lamination, and wax-coated cards cannot be written on with standard pens.
- Linseed oil treatment: A light coat of boiled linseed oil, allowed to cure, produces a water-resistant surface. NZ grows limited linseed (flax seed), so supply depends primarily on existing stocks of boiled linseed oil in hardware and paint inventories. The paper darkens substantially and becomes translucent. Legibility is reduced by 20–30% compared to lamination – acceptable only for bold, high-contrast printing at 12 pt or above. Curing requires 24–72 hours depending on temperature and humidity, during which the document cannot be handled.18
8. QUANTITATIVE SUMMARY
The following table estimates cumulative toner and paper savings from each measure. Savings are not strictly additive – they interact (e.g., efficient font on toner-save mode saves less additional toner than efficient font on standard mode, because both reduce the same toner deposit).
| Measure | Toner saving (approx.) | Paper saving (approx.) | Implementation cost |
|---|---|---|---|

What this means for production: Doc #5 estimates the national toner stock at 80,000–350,000 cartridges. At an average yield of 5,000–15,000 pages per cartridge, this produces 400 million to 5.25 billion pages at standard settings. Applying Tier 2 optimization across the production run increases effective output by a factor of approximately 2–2.5. This is the difference between producing 1,000 complete Recovery Library sets and producing 2,000–2,500 sets from the same toner stock.

- Doc #5 (Printing Supply Requisition and Management): Supply stocks, fleet management, and strategic framework. This document provides the operational detail that Doc #5 summarises.
- Doc #156 (Skills Census): Establishes actual fleet composition, toner stocks, and paper stocks – all of which affect optimization strategy.
- Doc #29 (National Printing Plan): Production scheduling and distribution. Tier classifications from this document feed into Doc #29’s production planning.
- Doc #31 (Manual Printing Methods): Post-toner printing. Some optimization principles (font selection, margin reduction, paper management) carry forward to manual printing methods.
- Doc #130 (Device Life Extension): Overlapping concern with printer fleet longevity.
- Doc #160 (Heritage Skills Preservation): Partnership-based integration of Māori knowledge systems. Governs content decisions for mātauranga-derived documents and te reo Māori bilingual formatting. Te reo typography requirements (Section 1.2), bilingual layout guidance (Section 2.5), and tier classifications for specific document types (Section 3) apply the print-specific implications of Doc #160’s mātauranga Māori partnership framework.
Combined savings estimate based on the individual measures described in this document. The 40–60% toner figure assumes toner-save mode (30–50%), efficient font (15–25% additional on the remaining toner deposit), and darkness reduction (10–20% additional). These are not strictly additive – the second and third measures act on the already-reduced toner deposit from the first. The 50–70% paper figure assumes duplex (50%) plus margin reduction (15–25% of remaining page count). See Section 8 for detailed breakdown.↩︎
HP states that EconoMode “can use up to 50% less toner” than standard mode. HP LaserJet product documentation. https://support.hp.com/ – Other manufacturers report similar figures. Brother states Toner Save Mode “reduces toner consumption by up to 40%.” Actual savings depend on document content (text-heavy documents save more than graphics-heavy documents).↩︎
Printer settings can be centrally managed on networked printers using printer management software (HP Web Jetadmin, Ricoh @Remote, Canon MEAP). On standalone printers, the settings must be changed on each machine’s control panel or through the print driver on each connected computer. Centralised management is strongly preferred.↩︎
The most widely cited source is a Printer.com analysis (2014) comparing toner/ink consumption by font at equivalent sizes. Similar results were reported by a University of Wisconsin-Green Bay study. These analyses have limitations – they test specific texts on specific printers – but the relative rankings are consistent across studies. See also: Ecofont (a Dutch company that developed a font with micro-holes to reduce ink consumption, claiming 50% savings – however, Ecofont requires proprietary software and is not available on most NZ systems).↩︎
EB Garamond is an open-source revival of the Garamond typeface distributed under the SIL Open Font License. It is available from Google Fonts and the EB Garamond project (https://github.com/georgd/EB-Garamond) and includes full Unicode coverage including precomposed macronised vowels (U+0100–U+017E Latin Extended-A block). This is the recommended production font for Recovery Library documents requiring te reo Māori text. Older proprietary Garamond variants (e.g., ITC Garamond, Garamond Premier Pro) should be tested for macron support before use. The Unicode Latin Extended-A block includes: Ā (U+0100), ā (U+0101), Ē (U+0112), ē (U+0113), Ī (U+012A), ī (U+012B), Ō (U+014C), ō (U+014D), Ū (U+016A), ū (U+016B).↩︎
NZ’s installed fleet is estimated at 30,000–60,000 commercial MFCs (Doc #5, footnote 17) and 200,000–500,000 desktop laser printers. A significant majority of desktop laser printers in NZ are monochrome. Colour laser printers and colour MFCs are present but represent a smaller fraction of the fleet, and their colour toner stocks are proportionally smaller.↩︎
Print darkness adjustment (sometimes called “print density” or “toner density”) is available on most laser printers. HP offers a 1–5 scale on many models. Reducing from 3 (default) to 2 produces a noticeable lightening of text but remains legible in good lighting. Source: HP product documentation; operational experience in managed print environments.↩︎
Automatic duplex printing has been standard on commercial MFCs for over 15 years and has become common on desktop laser printers since approximately 2010–2012. HP LaserJet Pro models from approximately 2012 onward, Brother HL-L series, and most Ricoh and Canon office MFCs include automatic duplexing. Source: manufacturer product specifications.↩︎
Show-through (the visibility of printing on the reverse side) depends on paper weight (heavier paper has less show-through), paper opacity (which depends on filler content), and toner density. At 80 g/m2 with standard toner density, show-through is minimal. At 70 g/m2 with standard density, it is noticeable but usually acceptable. At 70 g/m2 with toner-save mode, it is less visible because less toner is deposited. Source: general paper and print industry knowledge.↩︎
Non-printable margin (the area at each edge where the printer mechanism cannot deposit toner) is typically 4–5 mm for most laser printers and 5–6 mm for some MFCs. Exact figures vary by model. Source: manufacturer product specifications.↩︎
The distinction between documents that support an ongoing teaching relationship and documents that substitute for one is fundamental in knowledge documentation practice. See Doc #160, Section 4.5 for discussion of embodied knowledge and the limits of written documentation. For mātauranga Māori specifically, the appropriate role of printed documents is as reference support for learners in active teaching relationships — not as self-contained instruction manuals. This affects format decisions: a document that assumes contextual knowledge can use terminology without extensive definition, use diagrams without step-by-step labelling of every element, and focus on the steps where judgment is exercised rather than the steps that are automatic for someone with basic training.↩︎
Drum cleaning should be performed carefully and infrequently. The drum surface (typically organic photoconductor, OPC) is easily scratched. Use only lint-free, non-abrasive cloth. Isopropyl alcohol can be used sparingly on some drums – consult model-specific service documentation. On some models, the printer’s built-in drum cleaning cycle (accessible through the maintenance menu) is sufficient.↩︎
Standard ream wrappers for office paper include a moisture barrier (typically a polyethylene-coated or waxed paper wrapper). This barrier maintains the paper at its manufactured moisture content (typically 4–5% for office paper). Once the wrapper is opened, the paper begins equilibrating with ambient humidity. In NZ’s humid climate, this means moisture absorption, which causes curl and jam-prone behaviour. Open reams only when needed for immediate use.

NZ’s wool production (approximately 120,000–140,000 tonnes per year pre-event; Statistics NZ) provides an abundant source of strong thread suitable for bookbinding. Harakeke fibre (muka), extracted from NZ flax (Phormium tenax), is an indigenous alternative with high tensile strength, widely available throughout NZ. Cotton and linen are not grown commercially in NZ and depend on existing textile stocks.↩︎
Training time estimate based on bookbinding workshop practice. A basic three-hole pamphlet stitch can be taught in 15–20 minutes to someone with reasonable manual dexterity; a five-hole pamphlet stitch or basic Coptic stitch requires 30–45 minutes.

Hide glue production requires boiling collagen-rich animal tissue (hides, hooves, sinew, bones) in water for several hours, then reducing the liquid to a concentrated gel. The process is low-technology and has been practised for millennia. NZ’s sheep and cattle industries provide ample feedstock. Starch paste is produced by cooking wheat or potato starch in water – a low-skill process requiring only a heat source and cooking vessel. PVA (polyvinyl acetate) requires acetic acid (from vinegar production or chemical synthesis), acetylene (from calcium carbide, which requires a lime kiln and an electric arc furnace), and a polymerisation process. This dependency chain places PVA production well into Phase 3 or later. Source: general bookbinding and adhesive chemistry references; see also Doc #116 for the acetic acid and calcium carbide pathways.↩︎
NZ managed approximately 918,000 beehives as of 2023 (Ministry for Primary Industries, Apiculture Monitoring Report 2023). Beeswax is a byproduct of honey harvesting and is produced at roughly 1–2 kg per hive per year under active management. Paraffin wax is a petroleum distillation product; NZ has no crude oil refining capacity post-Marsden Point refinery closure (2022) and existing paraffin stocks are limited to candle and industrial wax inventories.↩︎
Linseed oil treatment for paper waterproofing has a long history – oiled paper was used for windows, wrapping, and waterproofing before glass and plastic became ubiquitous. The oil penetrates the paper fibres and, upon curing (oxidative polymerisation), creates a water-resistant film. Legibility is reduced because the paper becomes translucent, so this is suitable only for bold, high-contrast printing. Source: historical materials science literature; conservation references.↩︎
