ABSTRACT:
A color printing system which deposits colors on a separation by separation basis provides trapping to correct misregistration between printer output colors due to imperfect placement of the separation colors. The system includes a trapping calculation processor, determining trapping requirements based on visibility, measured in a color space in which equivalent color differences in human color perception are approximately equivalent values.
