Abstract

PROBLEM TO BE SOLVED: To increase the processing speed by coating the surface of a porous resin having continuous bubbles for allowing permeation of ink with a solvent according to a print pattern and fusing the pores to form a thin film layer permeating no ink thereby forming a print face comprising the thin film layer and a print part permeating the ink. SOLUTION: Outer circumferential fringe 4 is pressed to protrude the upper surface part 2 of porous resin and pores in the side face 3, outer circumferential fringe 4, and the side face 5 at the protrusion are fused and solidified to provide an ink unpermeating part. Consequently, only the upper surface part 2 becomes an ink permeating area for forming a print face. A porous resin plate subjected to this pretreatment is employed as a print member 7. The outer circumferential fringe 4 and the side face 5 are then thermally fused to protrude the upper surface part 2 thus preventing the ink from oozing out from other than the print face. The upper surface 2 is subjected to surface treatment depending on a print pattern before an ink permeating part 21 and an ink unpermeating part 22 are formed thereon.
