Method for producing special latent image pattern structure and special latent image pattern structure

摘要

To provide a special latent image pattern structure high in freedom degree of surface finishing of 2 patterns formed with sandwiching a hiding layer, and capable of exhibiting a continuous gradation pattern of variable information, which is different in each product.SOLUTION: There are related a special latent image pattern structure in which a latent image pattern having continuous gradation is visually recognized under a transmitted light by a synthetic image and a camouflage image formed at same position by sandwiching a hiding layer having light transparency and prescribed concealment property under a reflection light, a special latent image pattern structure in which a latent image pattern having continuous gradation is visually recognized under the transmitted light while it is visually recognized as an image with constant concentration under the reflection light by forming a positive image and a negative image with a latent image pattern on one surface side of the hiding layer, and constituting the camouflage image concealing the negative image on another surface side, and a creation method of data for the special latent image pattern structure.SELECTED DRAWING: Figure 1
