发明名称 Film and method for forming intaglio printing plates
摘要 A method of making a printing plate for intaglio printing having text characters and/or other indicia recessed therein for receiving printing ink which has a plurality of relatively thin barriers separating the text characters into a plurality of ink wells and defining surfaces for supporting a doctor blade during printing, the support surfaces intersecting the edges of each of the text characters at generally right angles and intersecting other supports at generally right angles to improve the quality of the printing of the text characters by minimizing the non-printing areas within the edges of the text characters and effectively retaining the shape of the edges of the characters, and a film or other photographic product for use in making such plates. The doctor blade supports are also designed to compensate for uneven material removal by chemical etching or the like so that the thickness of the supports are more uniform to minimize the non-printed areas within the edges of the characters.
