ANTI-PHOTOGRAPHIC/PHOTOCOPY IMAGING PROCESS AND PRODUCT MADE BY SAME

摘要

2075063 9111331 PCTABS00006 Several techniques for producing nonreplicable images. Images on mattes (M), particularly those of face value documents, and mattes are produced so as to acquire nonreplicable documents (10). Rendering of images as arrays of lineations (20) made of lines (12), dots (14) and swirls (16) in a predetermined pitch (d) format that varies minutely from the scanning pitch of a photocopier is detailed. The further rendition of these images as lineations, preferably of just dots and short hooked lines, surrounded by photographic disturbance medium such as lighter dyes/paints/inks/resins or print stuff arrayed in omnidirectional format frustrates photography copying as well.
