Abstract
Disclosed herein is a method wherein each pixel is tagged with a special VI (Variable Information) flag, which indicates the color of the pixel is variable or fixed. When the document gets created during raster image processing ('ripping'), the output CMYK of the VI and non-VI pixels are constrained to be odd and even numbers, respectively. In the meantime, a special TRC is created, and the VI colors are obtained through this special TRC at the odd indices, while the non-VI colors are obtained through the even indices. To enable the variable colorization printing, the job needs to be ripped once and saved. The saved job then can be reprinted multiple times with different TRCs that have the same values at the even indices, but different values at the odd indices.
