PRINTING INTAGLIO FOR PRINTING FUNCTIONAL INK AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method which can form a printing intaglio in the fine shape having a vertical groove.;SOLUTION: A manufacturing method of a printing intaglio includes: a step B of forming a resist layer 4 on a stainless steel substrate 2; a step C of forming the resist 4 subjected to patterning on the substrate 2 by removing the resist that is not exposed after performing exposure by using a mask 6 having a region formed with a metal layer; and a step D of forming a NiW layer 8 in a region where the mask does not exist by immersing the substrate in alloy plating liquid of nickel-phosphor-boron-tungsten. The printing intaglio is completed by removing the resist 4. The width and depth of the groove is almost 10 mm.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
