Abstract

PURPOSE:To form the printing film thickness thicker than what is formed heretofore in the gravure transfer printing. CONSTITUTION:Ink or a bonding agent is placed on a gravure and scraped by a doctor blade. Ink remains in patterns engraved on the gravure. When a pad 5 is pressed to the ink, the pattern-shaped ink is transferred to the pad 5. When the transferred pad 5 is pressed to a work, the pattern-shaped ink is transferred onto the work to complete the printing. The surface of the pad 5 is covered with a mesh 9 and fixed thereon to improve the transferability when the ink or the bonding agent is transferred and thicken the printing film thickness.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an intaglio transfer printing machine, and more particularly to an intaglio transfer printing machine using a pad so that a printing film can be printed thicker than before.

[0002]

2. Description of the Related Art In general, a plate (block) is a generic term for what is printed with ink on a printing paper. Broadly speaking, it is divided into four types: letterpress, intaglio, planographic and stencil. The area on the plate where the ink can be applied is called the image area, and the area where the ink does not (or should not) be called the non-image area. The convex portion means that ink is applied to the convex portion on the plate. Anciently made of stone, there are plates of wood, metal, synthetic resin, etc. Contrary to letterpress, intaglio is filled with ink in the depressions of the plate, and strong pressure is applied to transfer the ink to the paper. Gravure and engraved intaglio belong to this category. It used to be printed on intaglio printing presses (power plate presses) in the past, but recently more efficient intaglio ring transfer printing machines have been used. Gravure is intaglio printing that uses photographs. Special seal (abbreviation of special printing) is widely used for printing materials other than paper. In addition, the above is "Basic knowledge of printing terms 2
00 "(published by the Printing Society of Japan, 1982-11-20).

Conventionally, a pad for pad printing uses a smooth surface such as silicon rubber. In an intaglio transfer printing machine (pad printing machine), the ink or adhesive applied to the intaglio is first transferred to a pad and then transferred to a work for printing. The printed film thickness is determined by the depth of the intaglio, the properties of the ink and the adhesive. If you want to print a thick film, you can make the depth of the intaglio deeper, but even if you make it deeper, you cannot transfer to the pad, so the result is a thin print.

[0004]

The present invention has been made in view of the above circumstances, and an object thereof is to provide an intaglio transfer printing machine capable of printing a thicker printing film thickness in intaglio transfer printing. It is a thing.

[0005]

In order to achieve the above object, the present invention provides (1)
Put the ink or adhesive on the intaglio plate and scrape it off with a doctor blade, the ink will remain in the pattern engraved on the intaglio plate, and if you press the pad against the intaglio plate, the pattern-shaped ink will be transferred to the pad and transferred. In the intaglio transfer printing machine, in which the patterned ink is transferred onto the work by pressing the formed pad onto the work, the surface of the pad is covered with a mesh, and further, (2) the mesh is a stainless wire. In addition, (3) the mesh is a tetron wire or nylon wire, or (4) when ink or adhesive is placed on the intaglio plate and scraped off with a doctor blade, a pattern engraved on the intaglio plate is obtained. Ink remains inside, and when the pad is pressed against the intaglio, the pattern-shaped ink is transferred to the pad, and the transferred pad is removed. When pressed against the click, the intaglio transfer printing machine ink pattern is transferred onto the work, in which is characterized in that roughened surface of the pad by processing (embossing). Hereinafter, description will be given based on examples of the present invention.

First, the principle of intaglio transfer printing will be described with reference to FIGS. 3 (a) to 3 (c). In the figure, 1 is a doctor blade, 2 is an intaglio, 3 is ink or adhesive, 4 is a pattern, 5 is a pad, 6 is a pad holder, 7 is ink,
8 is a work. Ink or adhesive 3 is placed on the intaglio 2 and scraped off with a doctor blade 1. The ink 3 remains in the pattern 4 engraved on the intaglio. When the pad 5 is pressed against this, the pattern-shaped ink 7 is transferred to the pad 5. When the transferred pad 5 is pressed against the work 8, the pattern-shaped ink 7 is transferred onto the work 8 and the printing is completed. Generally, the intaglio 2 is made of metal, glass,
A pattern is engraved on a resin plate by etching or the like. The pad 5 is hemispherical and is made of silicon rubber.

FIG. 1 is a block diagram for explaining an embodiment of an intaglio transfer printing machine according to the present invention. In the figure, 9 is a mesh, and other parts having the same functions as those in FIG. It is attached. The surface of the pad 5 provided at the tip of the pad holder 6 is covered and fixed with a mesh 9. Thereby, the transfer rate when transferring the ink or the adhesive from the plate to the pad can be increased, and the printed film thickness can be increased. The mesh 9 may be made of a stainless wire, or may be made of a tetron wire or a nylon wire.

FIG. 2 is a diagram showing another embodiment of the intaglio transfer printing machine according to the present invention. In the figure, 10 is a rough surface, and other parts having the same functions as those in FIG. It is attached. The surface of the pad 5 provided at the tip of the pad holder 6 is roughened by a method such as graining. As a result, the printed film thickness can be increased as compared with the conventional pad printing.

[0009]

As is apparent from the above description, the present invention has the following effects. (1) Effect corresponding to claim 1: Since the surface of the pad in intaglio printing is covered with a mesh, the transfer rate when transferring ink or adhesive from the plate to the pad can be increased, and the printing film thickness Can be thickened. (2) Effect corresponding to claim 2: In claim 1, since the mesh covering the surface of the pad is a stainless wire mesh, the print film thickness can be made thicker than the conventional pad printing, and the film can be formed. Printing can be performed with good thickness uniformity. (3) Effect corresponding to claim 3: In claim 1, since the mesh covered on the surface of the pad is made of tetron or nylon, the print film thickness can be increased as compared with the conventional pad printing. Since the mesh has high flexibility, it is possible to perform work on a flat plate to a three-dimensional object in the same manner as conventional pad printing. (4) Effect corresponding to claim 4: In claim 1, since the surface of the pad is roughened in a textured manner, the printing film thickness can be made thicker than in the conventional pad printing, and the work is flat. It is possible to perform from the three-dimensional object to the three-dimensional object in the same manner as the conventional pad printing.
