Abstract

PURPOSE: To make a letterpress or a copperplate pertinent to an image reproducibility and easy in handling by a method wherein foamed portions and nonfoamed portions are formed on an original plate in accordance with intensities of light beams coinciding with densities of a copy.
CONSTITUTION: A side of a pigmented film 2 of an original plate 1 is put on a copy 5 and a transparent acrylic sheet 6 is laminated on a transparent film side of the original plate 1, thereafter, all of them are fixed to a base 7. When light beams of a lamp 8 comprising a plenty of ultrared rays are projected thereonto, the light beams penetrate the red pigmented film 2 through the original plate 1 and are arrived at the copy 5, then, are absorbed into protions of black letters 4 on the copy 5 and these portions are heated. A foaming agent in the pigmented film 2 contacting with these letters 4 is foamed at this moment and is protruded to make recessed and protruded portions, thus, a letterpress may be formed.
