ABSTRACT:
An original image including a line area and image areas separated from each other across the line area is subjected to a thinning process, whereby an iamge (10a) including a thinned line area (1a) and enlarged image areas (2a, 3a, 4a) is obtained. The enlarged image areas are sequentially expanded by a width of the thinned line area to form respective tint areas, and tint pattern data expressing respective shapes of the tint areas with prescribed colors are obtained.
