<p>PURPOSE:To achieve high accuracy by curing only a portion of ink applied to a picture element section of an intaglio plate and in contact with the recesses of said plate, and applying thereafter printing to a base board. CONSTITUTION:A planar intaglio plate 8 is composed of resin which transmits light and comprises picture sections 1 and non-picture sections 2, whereby ink 5, which is cured by application of light, is applied to the sections 1 by means of a roller 9. When light is applied to the ink 5 by means of an ultraviolet lamp 10 from the side of the plate where picture sections are not formed, the ink in contact with the wall of the sections begins to be cured, whereupon volumetric contraction of ink occurs, so that forces act on the ink so as to separate it from the wall, while curing of the surface of the ink, not in contact with the plate, is still in process. When a glass board 6 is engaged with the plate 8 to perform printing by moving a pressure roller 11, the surface of the ink is attached to the board 6. When the plate 8 is separated from the board 6, the ink is easily separated from the plate 8, so that the configurations of the recesses of the picture sections are precisely formed on the board 6.</p> |
