PRINTED MATTER WITH LATENT IMAGE, INTAGLIO FOR MAKING THE SAME, AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A latent image-printed matter capable of preventing the forgery, an intaglio for producing thereof, and a producing method of the latent image-printed matter are provided to offer a latent image effect to a printed product using the intaglio including asymmetric image line structures. CONSTITUTION: A latent image-printed matter(500) includes first protrusions(44) and second protrusions(42). The direction of edges on the second protrusions is different from the direction of edges on the first protrusions. The first and second protrusions are produced by an intaglio with asymmetric image line structures to express a latent image.
