Abstract
A document (10) is scanned to provide a digital image. At least one non-dropout color is selected (32) and transformed to a Luminance-Chrominance space (34). Each pixel of the scanned image is converted to the Luminance-Chrominance space (36) and the distance of each of the image pixels from the non-dropout color is determined (38). Each of the image pixels is converted to black (44) if the distance from the non-dropout color is less than or equal to a threshold value, and converted to white (42) if the distance is greater than the threshold value. The converted black and white pixels are then stored.
