PRINTED MATTER AND PRINT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a printed matter and a print system that can imbed attached information onto a base pattern in an invisible state and easily visualize the resulting pattern. SOLUTION: The additional information pattern is imbedded to the base pattern in an invisible state such that a step difference causing each stripe of a stripe pattern to be discontinuous is given at a border between a pattern of added information and the base pattern consisting of thin line stripes and a consecutive sequence of the step differences consisting of a plurality of the stripes at the border has a prescribed angle or over with respect to the direction of the stripes.
