Middletone Placement

In halftone reproduction, a means of determining the sizes of the middletone dots, accomplished during scanner set up by indicating the points on the input set up grayscale where shadows, diffuse highlights, and middletones are to lie, to ensure proper contrast in the final reproduced image. This controls the ultimate sizes of the middletone dots which, if not done properly, results in poor color reproduction. Other factors that must be taken into account during middletone placement are the anticipated dot gain from the printing process and the type of paper to be utilized. Also of importance is the screen ruling that will be used to generate the halftone itself.
