Abstract

PURPOSE: To obtain a printing type having excellent ink-impregnability and excellent ink-prervability, etc., by a method in which a soft polyurethane foam having a three-dimensional net work structure without cellular membrane is hot-pressed to give it a permanent deformation and then a rugged surface such as letters is formed on the foam by a special constitutional mode.
CONSTITUTION: A soft polyurethane foam 1, having a three-dimensional net work structure without cellular membrane and 20W60/cm cells, is hot-pressed into a thickness of 0.5W0.1 to give it a permanent deformation. And, the surface 3 in parallel with compressed direction A of the compressed foam 2 so obtained is contacted with a heating mold 5 with rugged surface 4 such as letter, etc. and then compressed in the right-angled direction to the compressed direction A under a condition that no heating is made from the back side 6. Thus, rugged surface 4' corresponding to the rugged surface 4 of the heating mold 5 is formed on the surface 3 of the foam 2 to obtain an objective print type.
EFFECT: Clear-cut printing can be repeatedly obtained without the needs to supply ink for a long period of time.
