Title: Resin letterpress with excellent film printability or the like
Inventor: KOMURA YUICHI
IPC: B41N1/12
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a resin letterpress for printing a film having a uniform thickness. SOLUTION: Many fine protrusions 11, 12, 13,..., are formed on a surfaces of protrusions 1 of the resin letterpress. Grooves 31, 32, 33,..., for holding coating liquids are formed between the respective fine protrusions. At a central portion of the protrusions, intervals of the adjacent fine protrusions are substantially constant. And, at a periphery of the protrusions, intervals of the adjacent fine protrusions are gradually narrowed toward a peripheral end of the protrusions. When the liquid is printed on such a resin letterpress, a holding amount of the liquid is less at the periphery of the protrusions than the central portion, and hence a thickness of the liquid printed on a material to be printed is thick at the central part and thin at the periphery. However, the liquid is attracted to the periphery by a surface tension of the liquid.  As a result, the liquid having uniform thickness is printed. When this is dried, a film having a uniform thickness is obtained.
