If you print fine art on matte or cotton rag papers, you have probably chosen them for their look and feel: a velvety surface, deep but soft blacks, and a texture that reads as a traditional print rather than a photograph. Any decision to coat them has to be weighed against that. A coating protects, but it also changes the character of the paper.
Why these papers are different
Matte fine art papers have a thick, absorbent receiving layer, and cotton rag papers have a fibrous base with natural texture. Ink sits close to the surface of a delicate coating that marks easily. Matte blacks in particular can be scuffed by a fingernail or a slip sheet, and the surface is sensitive to moisture.
The same absorbency makes them the most likely media to react to a solvent coating. Some uncoated or lightly coated papers, and some swellable surfaces, can darken, mottle, cockle or change tone when coated. Results vary a great deal from one paper to another, even between papers that look similar.
When coating makes sense
- Work that will be displayed unglazed, such as prints mounted to panels or hung in busy public spaces.
- Reproductions that will be handled often, such as portfolio pieces, menus or presentation prints.
- Prints in bright locations, where Colourjet’s integrated UV inhibitors add an extra layer of defence against premature fading.
For limited editions that will be framed behind glass and sold to collectors, many printmakers prefer to leave the paper uncoated and rely on glazing. That is a perfectly reasonable choice.
How to test safely
- Print a test image that includes deep blacks, skin tones or subtle greys, and plain paper margin.
- Let it dry thoroughly. Matte papers hold a lot of ink.
- Apply a light coat to half the sheet and leave the other half uncoated.
- Once fully dry, compare tone, black density, surface texture and paper white. Check whether the paper has cockled.
If you are using a semi-gloss or gloss coating on a matte paper, expect the result to look noticeably different from the original surface. ClearJet aerosols are a convenient way to try a light coat on a small sample; see ClearJet.
Ink type still matters
Most fine art printing on these papers uses pigment inks, which is the best starting point. If your printer uses dye inks, take extra care, as dyes on absorbent papers are especially vulnerable to bleeding and fading. Our compatibility hub covers both ink types.
