Adhering and transferring as a pattern ink having the shape of the image area on the lower peripheral surface. Subsequently, after moving the tampo to which the pattern ink has been transferred above the three-dimensional curved surface of the printing medium, the tampo is moved down to the three-dimensional curved surface and transferred to the lower peripheral surface of the tampo. After the shape pattern ink of the image area is pressed against the three-dimensional curved surface of the printing medium surface, the tampo is moved up to be transferred to the three-dimensional curved surface of the printing medium surface for printing.

  As described above, in the tampo printing method, a flat intaglio printing plate and a tampo having a lower curved surface such as an elliptical surface or a hemispherical surface are used for transfer printing on a three-dimensional curved surface of a printing medium surface. . Therefore, when making a flat intaglio printing plate, the shape of the pattern transferred and printed from the image line portion of the intaglio printing plate to the three-dimensional curved surface of the printing material surface is not distorted with respect to the pattern to be printed. In addition, it is necessary to design and make a plate by taking into account the curvature of the curved surface of the tampo and the printed material, etc., so it takes a lot of time to make an intaglio printing plate for tampo printing. Skill was required.
