<p>A method of printing paper or textile material comprises directing light through an array of electronically operated light shutter units (5 or 6 or 7 or 8) arranged in a two-dimensional area formed on the surface of a hollow control drum (1 or 2 or 3 or 4) towards a parallel light sensitive printing drum (9 or 10 or 11 or 12) rotatable in contact with material (13) to be printed, printing medium capable of adhering to the portions of the drum on which light has fallen being applied to the printing drum before said portions of the drum come into contact with the material to be printed. Selected light shutter units are set open and shut according to the pattern to be printed so that light passing through the open shutter units will affect the light sensitive printing drum whereby printing medium applied to the printing drum will adhere to the drum in the pattern to be printed for transfer during rotation of the drum to the material to be printed.</p> |
