ABSTRACT:
A method of printing on a sheet member a realistic image of an original, uses two different superimposed impressions with two different coloring media. A first printing plate is created by interposing at least two filters between the original and the film or photoconductive surface, and a second printing plate is created by interposing at least one filter between the original and the film or photoconductive surface. Then, the two printing plates are used to print the different impressions with two different coloring media.
