摘要：A color printing system which deposits colors on a separation by separationbasis is calibrated to determine a printed color responsive to a requested color, based ona mapping of device independent colors to printer output colors. The system providestrapping to correct misregistration between printer output colors due to imperfect
placement of said separation color. Such a system includes calibration data stored in adevice memory mapping a set of device independent colors to printer output colors; atrapping processor (18), using calibration data to determine device independent colorsfor printer colors. Also included is a trapping calculation processor, converting deviceindependent colors to a color space in which equivalent color differences in human colorperception are approximately equivalent values, determining whether to trap, a trapcolor, and a trapping location for the trapping color. An image modification processor isalso provided to alter the image accordance with any determinations of said trappingcalculation processor.
