Abstract

A technique is described whereby undesirable optical patterns of a printer output are eliminated through computer control on a collective basis. The concept is an improvement over previous techniques, in that it takes into consideration the undesirable attributes of implementing pattern elimination on an independent basis. Four patterns are discussed: Optical Illusion, Siamese Twin, Stutter and Moire patterns. It is quite common in computer printing applications to have justified right margins, with the justification being carried out by the extension of one or more inter-word spaces to fill out a line. In many situations, the optical appearance can be considered satisfactory.
