ABSTRACT:
A printing process for producing a print film whose developed image can be transferred to an offset plate or a screen printing screen or even to a cathodically-charged plate, is made by scanning an original and laser writing under the control of the scanning signals on a light-sensitive layer through a diffusion foil. The latent image is then developed and fixed and the resulting film transferred to the printing carrier such as the offset plate or screen printing screen.
