Choosing print substrates and stock, and what certified paper claims mean right now

The working taxonomy

Substrate talk sorts into a few working families, and knowing which family a job belongs in settles most of the decision before any brand name comes up.

• Coated stocks carry a mineral coating that holds ink on the surface: gloss for saturated colour and photographic work, silk/satin for colour with less glare, matt for a flatter, bookish finish. The coating is why brochures and catalogues print sharp.
• Uncoated stocks absorb more ink and read as warmer and more tactile: letterheads, text-heavy documents, anything meant to be written on. Colour sits softer than the proof unless the profile accounts for it (see our artwork prep guide on profiles).
• Boards are the heavy end, measured like all stock in gsm (grams per square metre); business cards, covers, packaging cartons. Stiffness, not just weight, is what the hand notices.
• Recycled and speciality: recycled content grades, textured and coloured stocks, and synthetic substrates for jobs that must survive weather or handling.

Weight and coating interact with process: heavy solids behave differently on coated and uncoated stock, and finishes like foil or spot UV have their own substrate preferences (covered in the finishes guide). Your printer's stock book is the real decision tool; this page is the map.

Fibre packaging is where the growth is

If the job is a box rather than a brochure, you are in the fastest-growing part of the substrate market. APCO's 2023-24 national packaging data puts paper and paperboard at 54 per cent of all packaging placed on the Australian market by weight, growing at 4.1 per cent a year since 2017-18 against 2.5 per cent for packaging overall, helped along by substitution away from plastics and foam. Post-consumer recycled content in fibre packaging reached 55 per cent. The same report lists the capacity being built to feed that demand: Opal's Maryvale recycled-containerboard conversion (2022), Opal's Wodonga corrugator (2023) and Visy's Coolaroo drum pulper (2023).

The certification layer: two schemes, two registers, both moving

Two chain-of-custody schemes stand behind "certified stock" claims in Australia, and they are different organisations with different registers:

Both are moving right now, which is why this reference page opens as news:

• FSC: the trademark standard FSC-STD-50-001 V3-0, the rule set for how the FSC mark goes on a printed job, became effective on 1 July 2026. Certificate holders, which includes printers and merchants who put the label on work, have until 31 December 2028 to transition, and FSC has released e-training covering the new requirements. If your shop approves FSC labels, someone needs to do that training before your next audit cycle.
• Responsible Wood: the Australian and New Zealand Sustainable Forest Management Standard (AS/NZS 4708), the standard underneath Responsible Wood certification, is being revised to align with the updated PEFC international benchmark, and public comment is open until 7 August 2026; the draft and submission form are on Responsible Wood's site. PEFC's own update was made to align with the EU Deforestation Regulation, so Australian certified-stock rules are being pulled into step with European due-diligence law.

Neither notice publishes a clause-by-clause change list on the page, so we are not summarising specifics beyond the dates, drivers and who must act; read the draft or the standard itself before relying on details.

What to actually do

• Selling certified stock: check your certificate scope and diarise the FSC trademark transition well before 31 December 2028.
• Buying certified stock: verify the supplier's certificate in the relevant register above rather than taking a logo on a spec sheet at face value.
• Have a view on AS/NZS 4708: the comment window closes 7 August 2026, and converters who live downstream of the standard rarely make submissions.
