Manufacturing method for anti-fake printed matter

The invention discloses a manufacturing method for an anti-fake printed matter. The manufacturing method comprises the steps that firstly, a base material is printed with a base pattern, wherein the base pattern is composed of a plurality of sets of parallel lines, and each set of parallel lines include the lines in two or more colors of LAB color space; secondly, the outline of a press concave-convex pattern is smaller than the outline of the base pattern, wherein the press concave-convex pattern comprises a plurality of parallel lines, the line width and the line distance of the press concave-convex pattern correspond to the line width in the overlapping area of the base pattern one to one, and the lines of the press concave-convex pattern are parallel to the lines of the base pattern; thirdly, a concave printing plate and a convex printing plate are manufactured according to the press concave-convex pattern, and press concave-convex machining is finished in the limited area of the base pattern on the base material. Only the colors of the base pattern can be seen when the manufactured printed matter is observed from the front face; the press concave-convex pattern is shown in the base pattern by adjusting the observing view of the base material, and the press concave-convex pattern and the base pattern are different in color; when the printed base material is rotated by 180 degrees in the horizontal direction, the colors of the press concave-convex pattern are exchanged as well.
