Finish / Smoothness

Finish is the smoothness or roughness of a paper's surface. Paper is processed to have a specific
type of finish, ranging from very smooth to highly textured.
Finish can significantly impact image quality. If paper is too rough, light patches and graininess
appear in solid areas. Halftone images also appear grainy. Dry ink does not fuse properly to
extremely rough paper, which causes deletions where the ink rubs or flakes off.
Smooth and coated papers produce sharp images because they reflect light more directly than
rougher papers. Use smooth or coated papers for proper dry ink transfer, to ensure the best
density and image detail, and to increase the appearance of glossiness. Using a highly
calendered / very smooth paper is especially important when printing fine lines and detailed
images.
A solid black on a cast coated sheet appears as though it has been coated or varnished.

method T 480. Gloss ranges are not rigidly fixed, which accounts for the slight overlap in values.

describe stock coatings.
