Coatings

Surface texture and coatings on card stock significantly affect toner adhesion (fuse grade), print quality, and feed
reliability. We recommend a vellum finish for the best printing performance. We do not recommend glossy coatings
and slick surfaces or surfaces that mimic laid finishes (glossy paper, not glossy card stock, is acceptable for some
printers). Paper smoothness also affects print quality. If the paper is too rough, the toner does not fuse to the paper
properly; if the paper is too smooth, it can affect feed reliability. We recommend smoothness to be between 100 and
400 Sheffield points (150–250 is optimal). Using media higher than 300 Sheffield could result in printing degradation.
