Abstract
A system for digitally trapping color images on a pixel-by-pixel is employed, whereby for each cyan, yellow, magenta and black color separation, an object-oriented trapping process is carried out. After each object is categorized, the original image is separated into a first copy and a second copy. Edge blurring is performed on the edges of the first copy of the original image; masking of a border region is completed on the second copy of the original image according to a laplacian filter, a difference recursive filter or other method. A merged image is created by combining the blurred edge first copy of the image with the mask bordered second copy of the original image; the mask is thereafter removed from the merged image.
