Abstract

PURPOSE:To print a high grade character of image of sublimable ink even on that a medium receiving a transfer which is low in surface smoothness and compatibility, by transferring the ink of a heat-sublimable ink medium activated by heat energy to an intermediate transfer medium and subsequently fixing said transfer medium to the medium receiving a transfer. CONSTITUTION:In such a state that an ink medium 12 and an intermediate transfer medium 15 are laminated, the coloring matter in an ink layer is diffused in the developer layer of e intermediate transfer medium by heat energy from a thermal head 11 to form an image. In such a state that the ink medium, the intermediate transfer medium and a medium 18 receiving a transfer are laminated, the ink medium is separated from the intermediate transfer medium and, at the same time, the intermediate transfer medium is adhered to the medium 18 receiving a transfer by heat or pressure from a roller 19 (S-part) and fixed thereto. At a finish time, since the running of the ink medium and the intermediate transfer medium on a supply side is stopped and only the medium receiving a transfer runs, the intermediate transfer medium is cut at a P-part. The ink layer consists of a sublimable coloring matter, a binder and an additive and, as the sublimable coloring matter, an anthraquinone dye and a printing dye can be used.

However, in one conventional technique, it was necessary to use special paper as the transfer medium in order to improve the color development and fixing properties of the sublimable dye. In other words, printing paper such as gravure paper or art paper, which has a very smooth surface, is used, and in order to further improve color development and fixing properties, it is necessary to use printing paper coated with a polymer that is highly compatible with dyes (for example, polyester resin). (synthetic paper with a coating layer) had to be used. In this way, since the transfer medium is limited, there is a drawback that the fields to which the printing method can be applied are limited.

Therefore, the present invention aims to improve the above-mentioned drawbacks of the prior art, and its purpose is not to limit the transfer medium, but to use paper with poor surface smoothness and plain paper with low compatibility with dyes. Another objective is to provide a printing method that can print characters and images using high-quality sublimation ink.

According to the above configuration of the present invention, the color developing layer (coat layer provided on the transfer surface of the transfer medium) of the transfer medium in the conventional system is supplied independently from the transfer medium. . That is, the sublimation ink is transferred to an intermediate transfer medium that is supplied separately from the medium to be transferred, and the formation of scratches on the medium to be transferred is performed by fixing the intermediate transfer medium to which the ink has been transferred to the medium to be transferred. It is carried out by In this way, the intermediate transfer medium plays the role of the color developing layer provided on the transfer medium in the conventional method, so the color development and fixing properties of the ink are very excellent. Since this is possible for the transfer medium, there is no need to use special paper for the transfer medium.

As described above, in the printing method according to the present invention, scratches are formed under conditions with very high transfer reproducibility, that is, on an intermediate transfer medium, and even on a transfer medium with a relatively poor surface smoothness. Because a large area of intermediate transfer medium is transferred all at once, the transfer efficiency is extremely high, making it possible to form high-resolution characters and images with high quality. Furthermore, the fixability of characters and images to the transfer medium is extremely poor due to the intermediate transfer medium.
