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.
Stock coating categories for Xerox Nuvera
Coatings can be applied to papers to increase smoothness.
When coated media are entered into the Stock Library, the coating type must be set to gloss,
high-gloss, semi-gloss, satin, or matte.
The following table provides descriptions of the coating types.
The gloss ranges in the previous table are measured at a 75 degree angle with the TAPPI test
method T 480. Gloss ranges are not rigidly fixed, which accounts for the slight overlap in values.
You can normally use the name or description of the finish, which is supplied by the
manufacturer, to determine the coating type. Paper mills may not be consistent in how they
describe stock coatings.
