Method of forming a photomask for a printing plate with an ink jet |
摘要 |
A method and apparatus for preparing a printing plate without the need for a photomask formed from a sheet of photographic film bearing the positive or negative of the image to be printed. According to the invention, an ink jet print head deposits ink onto a light-sensitive emulsion in a pattern which corresponds to either the positive or negative of the image to be printed. The printed pattern provides a photomask for subsequent exposure of the emulsion.
