ABSTRACT:
A visible representation of a colored image is created on a print-receiving area by resolving the colored image into p raster lines and resolving each raster line into q pixels, and creating a succession of sequences of digital words such that each word is associated with a pixel of the image and has one of n possible values, representing the color of the pixel. Consecutive words in each sequence of digital words are associated with adjacent pixels in a raster line of the image and consecutive sequences in the succession of sequences are associated with adjacent raster lines. First, for each of the n possible values of each digital word, a measure of the number of words that have that value is determined. Second, a set of the n possible values is selected, such that the number yielded in the first step for each value is not zero. Third, a subset of the selected set is identified such that pixels having the colors represented by the values in the subset do not appear adjacent each other in the image. One of m color levels (where m is an integer less than n) is assigned to at the values in the subset. A printing device creates a representation on the print-receiving area of the colored image such that all the pixels of the image having the colors represented by the values in the subset are rendered by a single one of the m color levels.
