Description

Method of transfer printing for solidity plate

According to the present invention, various graphic images including pictures, photographs, texts, film images, and the like may be applied to metal sheets such as steel sheets and stainless plates, and copper plates, aluminum sheets, porcelains, plates glass, plastic sheets, magnetic soft sheets or wood, and the like. The present invention relates to a transfer printing method for printing on a solid plate of the same nonmetals.

In general, as a method of printing on solid plate materials such as metals and non-metals, a transfer printing method using a transfer paper such as a silk screen printing method and a transfer printing method using the actual output of recently published No. 2000-61767 is known. .

The transfer printing methods using the various transfer papers can express various color expressions and colors of the original image in the same way as the silk screen printing method, and thus, non-metals such as metals, magnetics, glass, plastic, magnetic soft sheets or wood, etc. Is widely used for printing graphic images onto non-solid objects such as various fibers as well as printing graphic images onto solid objects.

However, most transfer printing methods using transfer papers known to date have problems such as poor workability due to the problem of the selection of the transfer paper and the complexity of the processing steps, the printing part being weak to ultraviolet rays, and the texture and adhesion of the printing surface being low.

For example, a method of transferring a graphic image onto a solid sheet using a transfer sheet is generally performed in the following essential steps, although there are some differences at each stage.

That is, the actual graphic image to be printed is printed on a rigid transfer paper using a printing machine or a copying machine, and a solid plate material for printing various glazes such as a varnish or enamel for adhesion of the transferred image. Coating the surface of the substrate, treating the transfer paper printed on the surface of the glaze-coated solid plate material, and applying a predetermined pressure and heat to the upper surface of the transfer paper, which is subjected to the solid plate material, by a thermal transfer machine for a predetermined time. Fusing the graphic image output to the surface of the solid plate material, removing the backing paper of the transfer paper from the surface of the solid plate material on which the transfer image is fused, and coating the surface of the graphic image fused to the surface of the solid plate material. Transfer printing is performed through the steps.

As described above, the method of transferring a graphic image onto a solid sheet material is a flexible and rigid material provided as a ready-made product, except in the case of using a transfer sheet having a special characteristic developed for a solid sheet material or a mass transfer printing method using a roller or the like. Among the transfer papers, the transfer paper manufacturers use hard transfer papers with specific characteristics for use on solid objects or plates, and the quality of the transfer prints made by the ready-made hard transfer papers so far is determined by the strength of the printing surface. It is low in quality due to its low scratching and peeling off, and in particular, pretreatment for coating glaze (glossy, acrylic, enamel, etc.) that enables the fusion of the transfer output on the surface of the solid plate, which is the transfer target. Transfer printing was possible only when the steps were essential. It will ever be required as a drawback was slow print speed low productivity and economy.

The present invention is provided to solve the problems of methods for transferring and printing a graphic image on a solid plate such as metals, magnetics, and non-metals, which are known so far, and the transfer printing method in a transfer printing method using a ready-made transfer paper.
