<p>A process for reproducing an original color image on a printing device includes separating each pixel of the original image into a plurality of color components to obtain an image density value for each color component at each pixel. A number of printing elements are selected for each color component, the number of printing elements being more than one for at least one of the color components. The printing density values for each color component having more than one printing element are separated into at least two pixel groups, the first pixel group containing printing density values less than or equal to an assigned maximum printing density value achievable with a single printing element for that color component, and the second pixel group containing printing density values greater than said assigned maximum printing density value for that color component. Printing elements are prepared for each color component having more than one printing element wherein a first printing element produces printing density values equal to the printing density values for each pixel in a first group and also produces printing density values equal to said assigned maximum printing density value for each pixel in a second pixel group, and a second printing element produces printing density values obtained by substracting said assigned maximum printing density value from the printing density value for each pixel in the second pixel group. <IMAGE></p> |
