Abstract

Frequently in electrophotographic printing machines, the original document is formed from a composite. The composite comprises portions from different original documents which are pasted together to form a new original document. In repro-ducing this new original, it is highly desirable not to copy the lines between different portions of the composite This may be achieved by diffracting the light. Thus, the light, which is reflected from the original document, is scattered sufficiently so as to disrupt any lines outlining the pasted regions. This is achieved by using a series of sanded trans-parencies which are positioned beneath the image to diffract the light of the original document. The transparencies are sanded in two directions until the surfaces have a frosted texture.
