ABSTRACT:
An ink transfer device comprising an ink transfer surface layer which may be connected to a porous ink storage body, such as used in a printing device or apparatus, having a porous structure with continuous pores therein and 8 to 30% porosity, and a surface ruggedness of less than 20 microns and ink mobilizable and storable porous ink storage body. The structure of the ink transfer surface layer and the ink storage body are produced respectively and successively by heat compression in a mold, thermoplastic powder of less than 50 microns diameter and of a little larger than the former ones. The inventive ink transfer surface layer enables uniform and efficient transfer of ink from the device even after repeated impressions of the device.
