Paper with a clay or polymer coating applied to one or both sides is coated paper. The coating can be dull, gloss, matte or high-gloss (cast coated). Commercial printers typically offer a selection of coated and uncoated papers for use on printing projects. The coated paper produces sharper, brighter images when used in printing and has better reflectivity than uncoated paper. Even the dull and matte coated papers, which are not very shiny, provide a much superior surface for printing than uncoated papers. These coated papers are usually coated on both sides of the sheet, but the coating can be applied to only one side, such as for use with labels.
Coated papers are manufactured at paper mills and should not be confused with paper that is coated at a commercial printing company during the printing process with UV coating or flood varnish, which is applied in-line on a printing press as a job print or afterwards.
Coated Paper Types
Gloss-coated paper is shiny and supports high contrast and a wider colour gamut than other types of paper. It is often used for marketing materials and magazines with a lot of colour images. Gloss paper lends a “pop” to colour images printed on it that doesn’t occur on uncoated papers. It can, however, exhibit glare, which makes any text harder to read.
Dull-coated paper is a better choice when images and text are both important in a print job. The reduction of glare on the dull-coated paper makes the text easy to read, while the coated surface delivers a smooth, high-quality base for image reproduction.
Matte-coated paper is similar to dull coated. It is a little lighter to the touch and less shiny than matte paper. From a quality standpoint, it is the least premium of the coated stocks, and it is usually the least expensive as a result.
Cast-coated paper is super-shiny paper. The surface is superior for the reproduction of images and is ideal for die-cutting. However, the heavy coating tends to crack, so it isn’t recommended for any printed piece that must fold. The paper is harder to work with and is considerably more expensive than other coated papers.
When Is Coated Paper Preferred?
The coated papers add a glossy, professional touch to magazines and similar publications. Paper resists dirt and moisture and requires less ink to print because it is not absorbent. Because the ink tends to sit on top of the paper rather than soak into it, the images are sharp. Coated papers are usually heavier than uncoated papers, which adds heft to a print job.
Because coated papers are smoother and have better ink holdout — is less absorbent — than uncoated papers, it is more suitable for certain types of finishing techniques such as flood or spot varnish or other finish coatings.
