Title:
特殊潜像模様形成体
Document Type and Number:
Japanese Patent JP7398638
Kind Code:
B2
Abstract:
To provide a specific latent image pattern formation body which allows visual confirmation of a latent image pattern without requiring high accuracy, on a relative position of a printing streak and an irregularity streak.SOLUTION: A specific latent image pattern formation body comprises: a substrate comprising thereon, an A area of a latent image pattern, and a B area of a background pattern; irregularity streaks which are arranged on the surface of the substrate with a same color to the substrate and at a prescribed pitch; and printing streaks which are arranged on the surface of the substrate with a color different from that of the substrate and at a prescribed pitch. The irregularity streaks have first irregularity streaks on the A area and second irregularity streaks on the B area, phases of the first irregularity streak and the second irregularity streak are different each other, the irregularity streaks further include, third irregularity streaks which are line symmetric to the first irregularity streaks, with center lines of the second irregularity streaks as a boundary, or fourth irregularity streaks which are line symmetric to the second irregularity streaks, with center lines of the first irregularity streaks as a boundary.SELECTED DRAWING: Figure 12
