Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing an intaglio plate (including cases referred to as tampo printing or blanket printing) for pad printing.

<Prior Art> For curved surface printing such as transfer printing applied to the inner surface or outer surface of a bowl, a pad made of a flexible material is used so that it can be adhered to the inner surface or outer surface of the bowl. In the case of transfer printing applied to the outer surface of the bowl, the pad has a smooth flat surface on the ink transfer surface, and in the case of transfer printing applied to the inner surface of the bowl, the ink transfer surface is smooth and on the inner surface of the bowl. It has a corresponding convex curved surface so as to be in close contact. Then, the curved surface printing with the pad has a thickness of 5 mm to 10 mm.
The intaglio plate is made on the hard metal plate of, and the ink is put on the cell by spreading the ink with a doctor or a roll and scraping it off, and then the pad is pressed against this to transfer the ink, and the pad on which the ink is placed. When is pressed against the outer surface or inner surface of the bowl, the ink is transferred to the bowl again, and curved surface printing is performed.

Such pad printing is performed not only for curved surface printing but also for printing on a large flat area.

However, in the conventional intaglio printing in pad printing, as mentioned above, a hard metal plate with a thickness of 5 mm to 10 mm was used, and one sheet was produced, so the plate material and the plate making cost were high. ing.

<Object of the Invention> The present invention can dramatically reduce the thickness of the plate material,
It is another object of the present invention to provide a method for manufacturing an intaglio plate for pad printing, which enables multi-product plate making at one time and eliminates the conventional defects.

<Structure of the Invention> The method for producing an intaglio plate for pad printing of the present invention is to make an intaglio plate as a plate material by applying copper plating and polishing to an original roll from which copper plating can be easily peeled off so as not to damage printing information. Peel off the copper plating layer while appropriately tearing,
Subsequently, it is characterized in that cutting into an appropriate size according to the print information and development into a plane are performed in an arbitrary order.

As the original roll from which the copper plating can be easily peeled off, a stainless roll or a roll obtained by plating an iron roll with a base copper and polishing it, followed by silver plating or an aselenic acid treatment can be used. Further, it is possible to use a roll having an oxide film formed on the surface after the iron roll is plated with nickel and polished.

Hereinafter, the details will be described with reference to examples.

First, an iron roll is plated with copper as a base and polished, and then silver-plated or treated with aselenic acid to prepare an original roll from which the copper plating can be easily peeled off.

Next, the original roll is plated with copper to a thickness of 150 to 200 μm and precisely cylindrically polished to form a plate material having a copper plating layer. And
After printing various types of printing information on the copper plating layer, developing, etching, resist peeling, and then chrome plating of about 5-10 microns to give printing durability, a mesh with various types of printing information The intaglio is completed.

Then, the printed information is peeled off so as not to damage it. In this peeling, first, a chisel is used to make a turning bar on both ends of the roll. Then, while tearing up this point with radio pliers, make a tear in the circumferential direction. After making a notch in the circumferential direction on both ends of the roll, make a notch in the lengthwise direction of the roll. At this time, the print information should not be cut. Then, when the cut edges in the length direction of the roll surface are uniformly turned up over the entire length, a large square mesh intaglio plate can be peeled off in a rolled state.

Then, roll the halftone intaglio plate into a flat shape by passing it between the rolls and cut it to the required size with scissors or a cutter according to the print information, and the production of the intaglio plate for pad printing is completed. .

The peeled halftone plate may be cut into an appropriate size according to the printing information, and then passed through the rolls to be spread in a flat shape.

Ink is dropped on the intaglio plate for pad printing that has been developed in a flat shape in this way, and the ink is drawn into a cell by stretching it with a doctor or a roll and scraping it into the cell. When the pad is pressed against the outer surface or the inner surface of the bowl, the ink is transferred to the bowl again, and curved surface printing can be performed.

<Effects of the Invention> As can be seen from the above description, the method for producing an intaglio plate for pad printing of the present invention is a method of producing an intaglio plate by subjecting an original roll to copper plating and polishing to produce the intaglio plate, and appropriately slicing The copper plating layer is peeled off, further cut into an appropriate size according to the print information, and developed in a plane shape.

Therefore, according to the method for manufacturing an intaglio plate for pad printing of the present invention, the thickness of the plate material can be dramatically reduced, and the cost of the plate material is extremely low.

Further, according to the method for producing an intaglio plate for pad printing of the present invention, since rolls are used, it is possible to perform multi-product plate making at one time, and plate making costs are low.
