ABSTRACT:
A system and methods for color matching overprinted graphic documents is described. Graphic elements in a document are examined to determine overlapping regions. The overlapping graphic elements in each region are examined to determine which graphic elements contribute color to the region. If two or more graphic elements contribute color, the region is an overprint region and information about the contributing graphic elements is used to create an overprint graphic element having contributed color. The original graphic elements and the overprint graphic elements are saved in a modified document, which is then processed to adjust the color of each graphic element to produce expected color on a target device that will display the modified document.
