熱昇華転写方法である。A thermal transfer printing method has been widely put into practical use as a small and low-cost printing method. As shown in FIG. 3, the thermal head 31. Ink medium 32. Installed in the order of transfer medium 33,
This is a method in which thermal energy from a thermal head is transmitted from a support layer 34 to an ink layer 35 to melt and transfer the ink to form an image. The ink is a thermoplastic material colored with pigments, dyes, etc., and the method using melting and adhesion is as follows:
A heat melt transfer method, and a method in which the ink contains a heat sublimable dye and the dye is dyed onto the transfer medium to form a pattern,
This is a heat sublimation transfer method.

２はインク媒体である。However, with conventional techniques, when the transfer medium is rough paper with poor surface smoothness, paper or film with poor chemical affinity for heat-melting ink or heat-sublimation dye, the transfer efficiency is poor and the image quality is degraded. I had dropped it. That is, as shown in FIG. 4, when a transfer paper 43 with poor smoothness is used, ink that is not in contact with the transfer paper when heat is applied will be transferred poorly and remain on the ink medium side (AA). , which was a factor in degrading the surface quality. In the figure, 1 is a thermal head, 4 is a thermal head, and 4 is a thermal head.
2 is an ink medium.
またこのような問題点は、転写ドツトの解像度が高くな

トの発生率が高くなる。Moreover, such a problem becomes very noticeable when the resolution of the transferred dots becomes high, and the incidence of dots that are not completely transferred increases.

The objective is to provide a printing method that can form high-resolution, high-quality characters and image quality on film as well.

固着させることを特徴とする。[Means for Solving the Problems] The printing method of the present invention includes a means for applying thermal energy corresponding to an image signal, a thermoplastic ink medium, an intermediate transfer medium, and a transfer medium, After the activated ink of the ink medium is transferred to the intermediate transfer medium, the intermediate transfer medium is fixed to the transfer medium with the ink transfer surface facing upward.
本発明の上記の構成による作用を従来の方法と比較して
説明する。The effect of the above configuration of the present invention will be explained in comparison with a conventional method.

写不良となる。1. In the conventional method, when rough paper with poor surface smoothness is used as the transfer medium, when heat is applied from the thermal head, the activated ink remains in the areas where the ink and the transfer medium are not shaken. Since the ink does not adhere (adhere) to the transfer medium, a transfer failure occurs when the subsequent ink medium is peeled off from the transfer medium.
これに対し、本発明による方法では、非常に平滑度の高

There was a phenomenon where the media side was taken over. This defective transfer phenomenon becomes more pronounced as the surface smoothness of the medium to be transferred is poor and the area of the ink to be transferred is small (such as in high-resolution dot transfer).

C is proportional to the area of the groove, F' A= f A・S,
It is expressed as FC=fC-8. Here, fA and fc are adhesive forces (adhesive forces) per unit area, respectively, and S is the area of the image. Further, FB is proportional to the length of the circumference of the image (provided that the thickness of the ink is constant), and is expressed as FB=fB-1. Here, fB is the cohesive force per unit length, and l is the length of the circumference.

Transferring the ink portion onto the intermediate transfer medium. (IAa in the figure) At the same time, the intermediate transfer medium is transferred to the transfer medium 16 by heat or pressure from the roller 18.

ある。When transferring by pressing, the intermediate transfer medium needs to be a pressure-sensitive adhesive material, and when transferring by softening or melting the intermediate transfer medium by heat, it needs to be a thermoplastic material. In the latter case, the adhesion temperature TA of the ink to the intermediate transfer medium, the temperature of the roller 18, and the temperature of the roller 18 are set so that the ink in the non-recorded area where no thermal image is applied does not adhere to the intermediate transfer medium due to the heat from the roller 18. TB, the adhesion temperature TC of the intermediate transfer medium to the transfer medium is T A>T B>T c
It is necessary to appropriately set the softening point or melting point of the ink and the intermediate transfer medium and the temperature of the roller 18 so as to achieve the following.

The supply side ink medium and intermediate transfer medium stop running,
Since only the medium to be transferred travels (the reverse is also possible), the intermediate transfer medium is cut at portion P in the figure.
以上が本実施例での転写のメカニズムである。The above is the transfer mechanism in this embodiment.

はない。However, in this case, in order to prevent the ink from adhering (blocking) to the intermediate transfer medium during storage and to ensure that the area to which heat is applied by the thermal head adheres firmly, the boundary between the ink and the intermediate recording medium must be It is necessary to provide a very thin silicon layer on the surface or to perform an interfacial treatment. Since the silicone layer and the interface treatment layer are very thin, they melt and diffuse during thermal imaging, and do not prevent the ink from adhering to the intermediate transfer medium.

It is also possible to carry out p2 at the same time. That is, the first
As shown in Figure (C), when a thermal image is applied by a thermal head (
The image is transferred to the upper part of the platen 17 and the intermediate transfer medium is fixed to the transfer medium at the same time. In this case, the fixation of the intermediate transfer medium is caused by suppression from the thermal head, thermal bias below the ink transfer temperature, or by platen 17.
Heating can be performed by any one method or a combination of the following.

たものになる。[Effects of the Invention] As described above, in the printing method according to the present invention, image formation is performed under conditions of extremely high transfer reproducibility, that is, on an intermediate transfer medium, and on a transfer medium with poor surface smoothness. Furthermore, since a relatively large area of intermediate transfer medium is transferred all at once, the transfer efficiency is extremely high, and high-resolution characters and images can be formed with high quality. Furthermore, the intermediate transfer medium provides excellent fixation of characters and images onto the transfer medium.
