Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intaglio transfer printing jig which flattens the printing surface of a printing material and enables distortion-free printing in intaglio transfer printing.

In general, one of the characteristics of intaglio transfer printing is that when printing on a substrate with an uneven shape, an elastic transfer body deforms along the shape of the substrate and transfers ink. Since the transfer body is deformed along unnecessary concave surfaces, there is a drawback that distortion occurs in character patterns, etc.
That is, as shown in FIG. 1, the intaglio 1 is usually flat,
It is made of hard steel or glass, etc., and as shown in Fig. 2, a character pattern is engraved on the printing position A, opening, C corresponding to the printing position A, opening, C of the printing substrate 2. Ink 3 is filled in positions A, C, and C.

Therefore, in FIG. 1, when the transfer body 4 first picks up the ink 3 from the intaglio plate 1, since the intaglio plate 1 is flat as described above, the transfer body 4 does not deform.
In the transfer body 4, the distance between the aperture and the aperture is a, and the distance between the aperture and the aperture is , but in FIG. Since the printing material 2 is deformed along the uneven shape of the printing material 2, the printing position A and the opening length of the printing material 2 on the transfer body 4 are A, and the length between the printing position opening and C is B, and this A of the intaglio 1, the difference between the opening distance a and the length A of the transfer body 4, and the opening of the intaglio 1,
The difference between the distance between C and the length B of the transfer body 4 causes distortion of character patterns, etc.

Therefore, in order to remove the distortion of the character pattern etc. mentioned above,
Conventionally, the positions between A, opening, and C of the intaglio 1 are determined according to the amount of deformation of the transfer body 4, that is, the lengths A and B after deformation. If the amount of deformation of the transfer member 4 is not always constant, distortion will occur in the character pattern, etc., making it difficult to design the transfer member 4.

This invention has been made in consideration of the above-mentioned problems, and its purpose is to make the printed surface of the printed material a flat surface in the recessed portions of the printed material having uneven portions in intaglio transfer printing. By removably fitting a fitting piece that is approximately the same height as the convex portion of the printing material, transfer printing can be performed on the printing material in the same pattern as when picking up ink from the intaglio plate with an extremely simple structure. The purpose of this invention is to provide a jig for intaglio transfer printing that can be used.

The present invention will be explained below with reference to embodiments shown in the drawings.

In FIG. 3, the same components and functions as those in FIG.
A jig 1 in which the upper surface 11a of the convex portion 11 of a and the upper surface 22a are flush with each other is removably fitted.

The jig 11 has a series of convex portions corresponding to the shape of the concave portions 1■ of the substrate 2 to be printed, and is covered with a plate-like thing for fitting, which has a concave portion corresponding to the shape of the convex portions 1± of the substrate 2 to be printed. It may also be fitted to the printed matter 2.

Further, within the concave portion 1 of the printing substrate 2, a certain shape is provided, and
A plurality of fitting pieces (not shown) having a certain length may be fitted along the recess 11 at certain intervals. Now, as shown in FIG. 1, it is assumed that the ink 3 is picked up by the transfer member 4 from the positions A, C, and C of the intaglio plate 1, and is transferred onto the printing surface 2a of the printing material 2.

In this case, since the jig tin is fitted into the concave portion of the printing surface 2a of the printing material 2, the printing surface 2a is connected to the top surface 22a of the jig 11 and the convex portion of the printing surface 2a. The upper surface 21a of the intaglio plate 1 forms a flat surface that is substantially similar in appearance to the upper surface of the intaglio plate 1.

Therefore, when the transfer body 4 is pressed against the printing material 2 and the ink 3 is transferred to the printing surface 2a of the printing material 2, the transfer material 4 deforms in the same manner as when the ink 3 is picked up from the intaglio plate 1. Therefore, the pick-up position of the ink 3 on the intaglio plate 1 corresponds to the pick-up position A, the opening, and the knob position C of the picker 5, that is, the distance a1 between the pick-up position A and the opening of the ink 3 on the intaglio plate 1. The ink 3 is transferred from the transfer body 4 to the positions of the convex portions 11 on the printing surface 2a corresponding to the pick-up positions A, C, and C of the ink 3 separated by a distance b, and the ink 3 is transferred from the transfer body 4 to the printing surface 2a of the printing material 2. In addition, the same character patterns and the like as those of the intaglio plate 1 are printed without distortion.

As described above, according to the present invention, in intaglio transfer printing, the concave portion of the printing material having the uneven portion is almost the same as the convex portion of the printing material so that the printing surface of the printing material is a flat surface. Since the fitting pieces of the same height are removably fitted, it is possible to transfer the transfer body to the printing material with an extremely simple structure in the same deformed state as when picking up ink from the intaglio plate. Therefore, character patterns and the like corresponding to intaglio printing can be printed on the printing material without distortion.
