DIRECT PRINTING METHOD USING LASER BEAM

摘要

PURPOSE:To form a printed picture of high quality at high speed without using any apecific printing plate, by selectively applying a laser beam to an undried printing paper subjected to solid printing. CONSTITUTION:A printing paper 1 fed through a paper feeder part 2 is subjected to solid printing at a printer part 3 and then selectively irradiated with a laser beam from a laser device 4 controlled by a controller 5 in order to fuse, evaporate and sublimate the ink printed on the part where no line is to be drawn in the solid print, thereby to form a necessary record picture on the paper 1 (a reference numeral 6 designates a processing part for the paper).
