Abstract
A quick and efficient method of testing the color registration on a multi-color electronic reprographic system includes the generation a latent image of a repeated basic test pattern across and down an photoconductive surface. Several images of this repeated test pattern are generated, one for each color in the reprographic system. Each test pattern is shifted a fixed amount so that the final output page displays a set of output figures. A figure of one color will be surrounded by at least one figure of each of the remaining colors of the reprographic system. Using this system a field technician can determine the level of misregistration between all of the colors.
