Abstract: In a process and device for producing screened formes with screens of any angle by means of at least one tracing beam moved over a display medium, which is switched on and off in accordance with the size and position of screen points, whereby a switching signal for the display beam is generated by a signal comparison between the image signal representing the tonal values of a model and stored screen thresholds representing the periodic basic structure of a screen grid, whereby co-ordinate increments corresponding to the progressive display are accumulated according to the screen angle to co-ordinate values and whereby several maximum binary position of the co-ordinate values form the addresses for reading out the stored screen thresholds, random figures are superimposed on the co-ordinate values.

Abstract: The invention pertains to a process and device for the optoelectronic scanning of originals. An original (4) is scanned by pixels and lines with the aid of a photodiode line (7). The picture signal values thus obtained for the individual pixels of the scanned lines are read from the integrated shift register (11) of the photodiode-line (7) and fed sequentially to an analogue-digital converter (17). The analogue-digital converter (17) converts only a proportion of the picture signal values from the original (4) to digital picture values for further processing; that proportion is defined by an original extract whose size and shape can be selected. To increase the scanning speed, the picture signal values which are to be converted to digital picture values are read from the shift register (11) at a speed which corresponds to the permissible operating speed of the analogue-digital converter (17) and fed to the latter. Those picture signal values not subject to conversion to digital picture values are read from the shift register (11) at a considerably higher speed.
