Method and device for imaging of a printing form

A method for imaging a printing form, in which a laser ( 140 ) generates a sequence of pulses ( 172, 220 ) of electromagnetic radiation corresponding to the image information of an image area ( 200, 202, 204, 206 ) to be generated on the printing form ( 118 ), and the image area ( 200, 202, 204, 206...

Zusammenfassung:	A method for imaging a printing form, in which a laser ( 140 ) generates a sequence of pulses ( 172, 220 ) of electromagnetic radiation corresponding to the image information of an image area ( 200, 202, 204, 206 ) to be generated on the printing form ( 118 ), and the image area ( 200, 202, 204, 206 ) to be generated on the printing form ( 118 ) is patterned according to the image information by interaction with the electromagnetic radiation, has the feature that the sequence of pulses ( 172, 220 ) of electromagnetic radiation is amplified by an amplifier ( 160 ); the amplifier ( 160 ) being discharged in a controlled manner by additional pulses ( 176, 222 ) corresponding to a non-image area ( 132, 208, 210, 212 ) of the printing form ( 118 ) in such a way that interference pulses of the amplifier ( 160 ) are prevented.
