Color Separation, Continued
The benday process involves photographing negatives through percentage
screens to filter the intensity of the image. Shading sheets are similar to the
benday process except, the artist uses a light-tack adhesive-backed pre-
printed percentage screen in the creation of the master artwork.
percentage of the screen represents the solidity of the image.
For example, a
20-percent screen is light, whereas an 80-percent screen is dark. Screens are
available as dots, lines, and patterns.
