Printing on specialty substrates such as synthetic paper, PVC, kraft, and metallic stock.
Most print jobs use coated or uncoated paper, but some products require tougher, waterproof, or visually distinctive materials. Synthetic paper can withstand washing, while PVC and polypropylene can shrug off moisture. Kraft paper offers an unbleached, natural look, and metallic stock provides a shimmer that no CMYK ink can replicate.
Why the substrate changes everything
Ink was designed for paper, which absorbs it. Non-porous materials such as PVC, polypropylene, and synthetic paper do not absorb ink in the same way, so they require either UV-curable inks that set instantly under a lamp or latex and eco-solvent inks that bond to plastic. Sending a plastic substrate to a press set up for paper can result in ink smearing or peeling. This is why specialty substrate printing is a materials-and-method decision, not just a stock swap, and why it pays to confirm both before committing to a run.
The texture and color of the stock also influence the final result. Uncoated natural stocks, like kraft paper, absorb ink and mute colors. Therefore, designs meant for kraft paper should emphasize the paper's inherent warmth rather than using bright, saturated colors.
The specialty substrates worth knowing
Synthetic paper
Synthetic paper, typically made from polypropylene or polyester film, resembles paper in appearance and feel. However, synthetic paper is waterproof, tear-resistant, and durable. It is ideal for use in menus, field guides, maps, plant tags, and any other materials that may encounter moisture or frequent handling. Synthetic paper accepts full-colour printing well with the appropriate inks and can be folded cleanly without cracking.
PVC and polypropylene
Rigid PVC and flexible polypropylene are the preferred plastics for durable cards, tags, outdoor signage, and reusable items. PVC prints crisp, full-color images and is the standard for membership and loyalty cards. Polypropylene, on the other hand, is lighter and popular for folders and document covers. Both materials require UV or solvent inks to bond reliably.
Kraft and recycled stock
Kraft board and recycled uncoated stocks feature an unbleached, natural appearance that conveys a handmade or eco-conscious brand. These materials are ideal for packaging, swing tags, and rustic labels. However, the brown base can alter printed colors, so it is worth ordering a printed proof on the actual stock.
Metallic and textured stock
Metallic pearlescent papers and textured stocks like linen or felt enhance the tactile premium feel of invitations, certificates, and luxury packaging. Colors printed over the metallic base provide a soft sheen, while textured stocks scatter light to minimize fingerprints.
| Substrate | Key property | Typical use |
|---|---|---|
| Synthetic paper | Waterproof, tear-resistant | Menus, tags, field guides |
| PVC and polypropylene | Rigid or flexible plastic | Cards, folders, outdoor signage |
| Kraft and recycled | Natural uncoated look | Eco packaging, swing tags |
| Metallic and textured | Sheen and tactile finish | Invitations, luxury packaging |
Cost, durability, and selecting the right material
Specialty stocks cost more than plain paper, both in the material itself and often in the ink and setup, so the upgrade should be tied to a real need rather than novelty. The honest question is how the piece will be used. A menu that gets wiped down every service, a plant tag left outdoors for a season, or a card that lives in a wallet all justify a waterproof or plastic substrate because ordinary paper would fail early and get reprinted. A single-use flyer does not.
Durability and appearance often conflict. Plastic substrates last the longest but can look clinical, while kraft and textured stocks have a characterful appearance but are less rugged. Matching the material to the job usually involves prioritizing what matters most for that piece. This could be water resistance, a premium feel, an eco-friendly message, or the lowest cost that still withstands handling.
When a coated paper is enough
Not every demanding job requires a synthetic substrate. A good silk or matte coated paper with a protective laminate can handle plenty of moisture and wear at a lower cost than film. Additionally, it folds and glues more easily. It is worth considering whether laminated paper meets the durability requirements before opting for plastic, since the cheaper option often suffices. Reserve true synthetic and plastic stocks for pieces that will be genuinely wet, bent repeatedly, or kept for years. Let a printed sample settle any doubts before placing a full order.
Preparing artwork for non-standard stock sizes
Specialty materials require a bit of extra file preparation, as the stock contributes significantly to the design.
- Ask the printer which ink system is required for the material, as UV, latex, and eco-solvent inks each suit different substrates.
- Order a printed proof on the actual stock, as colors on kraft or metallic paper look nothing like the same file on white paper.
- Mark any area that requires a white underprint on clear, kraft, or metallic stock to ensure colors remain true.
- Avoid using heavy solid coverage on textured stock, as ink can sit unevenly across the grain.
- Confirm the folding and die-cutting behavior, as plastics and heavy board crease and cut differently from paper.
Adhesive-backed specialty materials follow the same logic as label stock, so our notes on durable label materials and on vinyl decals and adhesives are a useful companion when the substrate has to stick to something.
Disc-Print offers printing on specialty substrates.
Disc-Print runs synthetic paper, PVC, polypropylene, kraft, and metallic and textured stocks with the correct UV and eco-solvent ink systems, so a waterproof menu, a batch of PVC cards, or a kraft packaging run all bond properly and hold up in use. We can proof colour on the exact stock before the full run, advise which substrate fits the durability and look you need, and handle the die-cutting and finishing that specialty materials often require. If you are unsure whether synthetic paper or coated stock is right for a wet or heavily handled job, we will send samples so you can feel the difference.
You can explore the range in our printing services category and the print quality and materials section, or see how substrate choice plays into folding carton packaging. To scope a specialty job, send your artwork, the material you have in mind, and the quantity through our contact page and ask for a proof on the real stock.
