A sheet of multi-layer seal film is cut along desired boundary lines for coloring, and is adhered on a silk screen. Printing is effected by repeating a series of procedure as follows. When seal film sections which have been cut into patterns to be printed in a common color are removed from the screen, ink permeable holes are formed to carry out printing, and the ink permeable holes after printing are closed with resin. A section with at least one gradational pattern is printed by forming a large number of screen-mesh apertures through a covering film of the resin. For additional printing, a piece of already-cut seal film is adhered on the screen prior to applying the resin liquid to the screen.
