This invention relates to latent image printed matter which uses a combination of projecting image lines of a color identical with or similar to that of a printing material and image lines of a color different from that of the projecting image lines to prevent the forging and altering of the printed matter and discriminate between genuine printed matter and forged printed matter easily; and a printing method for such printed matter. When colored regularly spaced linear image lines the color of which is different from that of projecting image lines, such as a multi-line pattern the color of which is identical with that of a printing material are printed on these projecting image lines, printed matter the characters and pattern on which can be recognized only when they are observed from a predetermined direction is obtained. <IMAGE>
