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> |
