Abstract
Apparatus and method for producing selectively edited reproductions of an original documents with high productivity. Selected areas of information on the originals are bounded by a loop of a first or second type of highlighting material to indicate the area for reproduction in one or more treatment modes such as color-accenting. Alphanumeric character codes, written using the highlighting means, designate the treatment(s) to be applied. The two types of highlighting material respectively indicate that the selected area is located within or outside the boundary. By scanning the highlighted originals, the boundaries are distinguished and the character codes are detected. The resulting output signals are processed using boundary detection and character recognition algorithms and the resulting information is stored in a bit map. The information is used to adjust a charged image version of the original on an image-bearing member using an LED or other light source. The appropriate image frames, exposed in accordance with the highlighting, are then developed and transferred.
