Abstract
Method and apparatus are provided for reproducing information on a document sheet so that copies are provided with such information, yet also include additional information that may vary from copy to copy. An electrophotographic reproduction apparatus is provided to optically reproduce the information on the document sheet. The document sheet is provided with a black patch (or placed in a transparent folder having such patch) that is located in the area corresponding to where the variable information is to be written. The document sheet is then placed on a digitizing tablet to provide signals indicative of the area of the black patch. The document sheet is then placed on the exposure platen and optically copied. In response to the signals an LED printhead writes the variable information on the same image frame used to optically copy the original to provide full machine speed copying. The document sheet with black patch may be produced by the apparatus.
