ENGRAVING METHOD OF RESIN PRINTING PLATE

摘要

PURPOSE:To make the simultaneous formation of a mount part and base part possible by forming a main pattern which has a slightly large contour and energy ray transmittance and a pattern for the base part having the larger contour and energy ray semi-transmittance as a masking film and providing an effect of shielding the energy rays to the extent of prohibiting curing of a resin liquid to the outside part. CONSTITUTION:A negative film 3 is placed on a transparent base plate 5 and a transparent film 6 is put thereon. A photosetting liquid resin is poured into a frame body 7 to form a photosetting liquid resin layer 2 on the film 6. a transparent base film 11 is placed atop the layer 2 and the masking film 4 is put thereon. The resin layer is exposed to the light from a light source 51 from the outside of the base plate 5 and the film 4. The lower part of the resin layer is cured in the part corresponding to the main pattern 3 of the film 3 by the exposing to form a relief part 21. The resin layer cures thickly in the part corresponding to the overlapped parts of the patterns 44, 46, by which a mount part 22 united integrally with a relief part 21 is formed.
