<p><P>PROBLEM TO BE SOLVED: To enable accurately to control a beam shape concerning flexibility, precision and beam positioning by enabling to obtain extremely high powder density and high energy by a cheap system in a method for manufacturing a printing form plate for intaglio printing, and to raise a durable life of a printing form plate by enabling accurately to control a beam output even when laser output is extremely high and by enabling precisely to form a volume of a minute cell of the printing form plate for intaglio printing. <P>SOLUTION: A chrome layer is formed on the printing form plate, at least one laser beam fiber is pumped with at least one laser diode by using at least one laser diode, at least one laser beam generated from the laser fiber is introduced to a surface to be worked via at least one optical system containing at least one modulator, and a recess for receiving printing ink is formed on a surface to be worked with at least the modulated one laser beam. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
