  There is a problem that the fixed colorant is peeled off by rubbing in the colorant when the article on which the screen printing is applied is picked up by a person, placed on a table, or overlapped with another article. there were. For these reasons, there is a demand for a structure on which screen-printed articles are hard to peel off the fixed colorant.

  The method disclosed in Patent Document 1 is a method in which a screen printing plate 108 is arranged opposite to a character-shaped convex portion 101 a of a printed material 101 and a colorant 109 is applied with a squeegee 110. An opening 108 a is provided in a portion of the screen printing plate 108 that faces the character-shaped convex portion 101 a, and the colorant 109 transmits the screen printing plate 108. The transmitted colorant 109 is applied at a position protruding from the printed material 101, and the boundary with the hot stamp foil layer 103 provided on the surface of the character-shaped convex portion 101a is exposed on the side surface of the convex portion 101a. Therefore, when rubbing occurs in the colorant 109 from the side surface direction of the convex portion 101a, there is a problem that the colorant 109 is easily peeled off from the boundary.

  Further, when fixing the colorant 109, it is necessary to move the squeegee 110 in the F direction while pressing the squeegee 110 against the screen printing plate 108, and the pressed screen printing plate 108 is bent with respect to the surface to be fixed. There is a concern that the positions of the opening portion 108a and the character-shaped convex portion 101a are shifted and are fixed to a range different from the target printing range. For this reason, it is necessary to accurately set the pressing force of the squeegee 110 and the pre-printing arrangement of the screen printing plate 108, and there is a problem that it is not easy to perform screen printing.
