Zusammenfassung:	To provide a printed matter incorporated with an invisible copy-restraining letter by variation of high color tones without using particular color inks by using four process colors of CMYK.SOLUTION: A printed matter of an embodiment includes a first region remaining when copied, and a second region disappearing when copied. Dots are arranged in a random manner in the first region and the second region concurrently, sizes and color constitutions of the dots are different as for the first region and the second region, the dots are large in size so as to easily remain when copied in the first region, for example, K color is used plenty, and the dots are small in size so as to disappear when copied in the second region, for example, K color is not used.SELECTED DRAWING: Figure 1 【課題】ＣＭＹＫのプロセスカラーの４色を用いることによって、特色インキを用いることなく、高い色調のバリエーションで、視認されないコピー牽制文字を組み込んだ印刷物を提供すること。【解決手段】実施形態の印刷物は、複写された場合に残る第１領域と、複写された場合に消失する第２領域とを備える。第１領域および第２領域にはともに、網点がランダムに配置されるが、第１領域と第２領域とでは網点のサイズおよび色構成が異なり、第１領域では、複写された場合に残りやすいように、網点は、サイズが大きく、例えばＫ色が多く使用され、第２領域では、複写された場合に消失するように、網点は、サイズが小さく、例えばＫ色は使用されない。【選択図】図１
