Abstract

In order to permit a printing form to be produced by laser-induced thermotransfer in a simple manner that can be integrated into the printing machine, without the gases which arise during laser imaging detectably disturbing the transfer of material from the transfer foil, i.e., the image quality, a strip-type transfer foil with a strip width that is small relative to the printing form width is used. During imaging, this transfer foil is conveyed continually between the printing form and the laser beam, close to the printing form surface, and is thereby moved simultaneously and synchronously with the movement of the laser beam across the printing form width.
