Abstract
A printed matter such as an advertisement material is provided. The printed matter includes a printing layer provided on a base plate and having various colors printed thereon such that half-tone dots of the respective colors are printed and overlap at a predetermined portion. A projection layer made of transparent epoxy resin or ultraviolet resin for covering only a particular portion of the printing layer intended to be emphasized, is formed on the printing layer. Also, a plurality of hemispherical protrusions made of transparent ultraviolet resin is formed on the projection layer using a screen printing method. The respective colors of the printing layer disposed beneath the hemispherical protrusions are refracted at different refraction angles to then be visually perceived. Thus, the colors, which are not visually perceived by naked eye, are made visible, thereby providing a three-dimensional effect to the printing layer.
