Abstract
An electrophotographic reproduction apparatus and method are provided for reproducing an original document sheet that includes a continuous tone pictorial information area and a line-type information area. Rather than reproducing the entire document sheet with screening of both types of information, means are provided for selectively screening only the pictorial information area on the reproduction. The means of one preferred embodiment comprises a programmable illumination source that is programmed through inputs by the operator using a digitizing tablet to selectively image portions of a screen onto a charged photoconductive web prior to development of the electrostatic image formed on the web so that only the area on the web receiving the pictorial image is exposed to the screen. In another embodiment the programmable illumination source, such as LED's, modulates the portion of the image frame receiving an optical exposure of the pictorial information with the screen type exposure so that the pictorial information only is reproduced with a screen pattern. In still another embodiment a sensor automatically senses and determines the image portions to be selectively screened.
