Abstract

The invention is directed to a method of printing using an ink jet printer which jets a first color ink and a second color ink onto a print medium at locations defined by an image area having a plurality of pixels. The method inhibits intercolor bleeding between the first color ink and the second color ink. A first array of pixels in the image area is selected, with the first array being an M.times.N array wherein M and N are integers. A portion of the first array is defined as a second array of pixels, with the second array being an X.times.Y array wherein X and Y are integers. The integers X and Y are smaller than the integers M and N, respectively. The pixels within the second array are examined. The pixels within the first array are altered if the examined pixels within the second array substantially all correspond to the first color ink.
