This invention relates to a printed matter which visualizes a latent image pattern by periodically formed raised image lines when observed in a tilted state, and provides an anti-counterfeit printed matter which allows latent images having different densities to be observed from a plurality of observation angles. In the anti-counterfeit printed matter, a region serving as a shade of a latent image is formed in addition to image lines forming a latent image portion and those forming a background portion, or at least one of the latent image portion, the background portion, and the shade portion is divided into a plurality of regions, and image lines formed in the divided regions are arranged at different angles, thereby forming a three-dimensional latent image observed from a plurality of directions. |
