How can we help?


Paper types and equivalence

Depending on the product, we offer different paper types as well as the possibility to add protection (on some paper types) for a more durable product. Also, different paper standards are used worldwide with North America using lb to define paperweight vs. the rest of the world using gsm instead.

Paper types

Depending on the product category you choose, we can offer different paper types, weights and the option to add protection. There are 2 different paper types available:

Matte (uncoated)

Matte paper is uncoated. It is generally more expensive than coated paper, less consistent in different countries and is also not available as widely around the world. Matte paper should be avoided with heavy ink coverage, as it can look mottled. Heavy ink coverage is better suited to coated stocks with protection to stop rub and scratching (read more on protection below).

Silk (coated)

Silk paper is a coated paper with a slight sheen. It should be used for documents with heavy ink coverage. You can apply both a matte or glossy protection to silk paper (more on this below). Silk paper should not be used for pages intended to write on.



Protection is a good way to protect against scratches and against colour rubbing off, especially on heavily coloured documents. We recommend always selecting protection for heavily coloured cover pages on saddle-stitched or perfect bind documents in order to avoid cracks in the spine. We offer both glossy and matte protection.


Important notes

  • Protection can be added only on silk paper (matte paper cannot be laminated due to its physical characteristics)
  • To ensure the best quality, protection options are available with 250gsm/100lb cover or thicker silk paper
  • Protection can be added only to cover pages (front and back) of the brochures
  • Protection can be added to a single side or to both sides of flyers and business cards
