PURPOSE:To form a high molecular film for electronic parts having a desired pattern in a uniform film thickness, by transferring a resin-containing ink filling an intaglio printing provided with plural small pores to an object to be printed through a dry offset plate by using a roller. CONSTITUTION:A small orifice group 1 wherein the depth is 3-50mum, the average diameter of the opening part is 1-500mum, the area of the opening part is 1-80%, the sum recessed part volume of small orifices per 1m<2> is 0.05-5mm.<3> and average shortest distance between the small orifices is 10-2,000mum is provided to an intaglio printing 2. This intaglio printing 2 is filled with an ink consisting of resin with viscosity of 2,000-10cp (e.g., phenolic resin, polystyrene) and a solvent and this ink is transferred to the pattern part of a dry offset plate 5 preliminarily provided with a pattern by a roller. In the next step, said ink 3 is transferred to the surface of an object 7 to be printed by a blanket roller 6 to form an objective high molecular film 8. |
