Abstract:

PROBLEM TO BE SOLVED: To limit document copy by a pattern of removable color-subtracting microdots when an image is recorded on a medium, the medium is chemically processed, and a document is formed. SOLUTION: The pattern of removable microdots 16 positioned in the depth direction are formed on any place within the transparent protecting film of an original copy 10 and a supporting layer supporting at least one image forming layer, and image copy inside the medium is limited. The dot 16 cannot be detected by naked-eyes, but the dot can be detected by a copying machine programmed so that copying is stopped when the micro-dot is detected.
