Description

TECHNICAL FIELD The present invention relates to a combination of a print manufacturing method and a thermal transfer sheet.

2. Description of the Related Art Conventionally, there has been known a method for producing a sublimation transfer printed matter using a thermal transfer sheet provided with a dye layer containing a sublimation dye. The sublimation transfer method has the advantage of smooth gradation expression, and the dye layers constituting the thermal transfer sheet used are three colors of Y (yellow), M (magenta), and C (cyan). In many cases (see, for example, Patent Document 1), a full-color image is formed with these three colors, which sometimes results in poor color reproducibility.

In order to improve the color reproducibility in the sublimation transfer method, it is conceivable to use a thermal transfer sheet having dye layers of other colors in addition to YMC. As a result, thermal damage is accumulated, and there is a concern that fusion between the thermal transfer sheet and the receiving layer may occur, or density may decrease. In addition, when the number of dye layers increases, a new problem arises that image formation takes a correspondingly longer time.

1. Printed Matter Manufacturing Method A printed matter manufacturing method according to an embodiment of the present invention will be described in detail below.

FIG. 1 is a configuration diagram of an apparatus for carrying out a print manufacturing method according to an embodiment of the present invention. Note that the apparatus shown in FIG. 1 is an example of an apparatus for carrying out the print manufacturing method according to the embodiment of the present invention, and the present invention is not limited to this apparatus.

1-1. Preparatory Process As shown in the configuration diagram of the apparatus 100 shown in FIG. A step of preparing a thermal transfer sheet 40 for intermediate transfer medium is performed.

There are no particular limitations on the specific configurations of the transfer target 10, the transfer target thermal transfer sheet 20, the intermediate transfer medium 30, and the intermediate transfer medium thermal transfer sheet 40, which are prepared in this step. An example of each specific configuration will be described later.

1-2. First Image Forming Step Next, as shown in the configuration diagram of the apparatus 100 shown in FIG. Then, a step of forming a first image P1 is carried out using the thermal head H1 and the thermal transfer sheet 20 for transfer material.

FIG. 2 is a graph showing an example of spectral density for each wavelength of the first image P1.

For example, the thermal transfer sheet 20 for transfer material is provided with a yellow dye layer containing yellow dye Y1, a magenta dye layer containing magenta dye M1, and a cyan dye layer containing cyan dye C1. FIG. 2 shows an example of the spectral densities of the first image P1 for each wavelength when the solid black first image P1 is formed. In order to make the explanation easier to understand, an example in which the first image P1 is solid black is taken as an example, but the first image P1 is not limited to this, and the final image to be manufactured is not limited to this. 1 is an image formed by using a yellow dye Y1, a magenta dye M1, and a cyan dye C1 in the thermal transfer sheet 20 for a transfer body based on a preset color table.

The measurement of the spectral density for each wavelength of the first image P1 is not particularly limited, and can be measured using a commercially available spectral densitometer. The spectral densities of FIG. 2 and FIGS. 3 and 4 shown below were measured using an i1i02 (X-rite spectrodensitometer).

1-3. Second Image Forming Step On the other hand, as shown in the configuration diagram of the apparatus 100 shown in FIG. 30, a step of forming a second image P2 by inverting the first image P1 using the thermal head H2 and the thermal transfer sheet 40 for intermediate transfer medium.

FIG. 3 is a graph showing an example of spectral density for each wavelength of the second image P2.

Here, for example, the thermal transfer sheet 40 for intermediate transfer medium is provided with a yellow dye layer containing yellow dye Y2, a magenta dye layer containing magenta dye M2, and a cyan dye layer containing cyan dye C2. FIG. 3 shows an example of the spectral densities of the second image P2 for each wavelength when the solid black second image P2 is formed using layers. Note that, like the first image P1, the second image P2 is also black solid to make the explanation easier to understand, but the second image P2 is limited to this. is a reverse image of the printed matter P to be finally manufactured, and based on a preset color table, the yellow dye Y2, the magenta dye M2, and the cyan dye C2 in the intermediate transfer medium thermal transfer sheet 40 It is an image formed by

1-4. Transfer (Superposition) Step Next, as shown in the configuration diagram of the apparatus 100 shown in FIG. A step of transferring the upper second image P2 onto the first image P1 on the transferred body 10 is performed, and a desired printed material P is formed.

FIG. 4 is a graph showing an example of spectral density for each wavelength of a print P formed by superimposing the first image P1 and the second image.

FIG. 4 shows an example of spectral densities for each wavelength of a printed matter formed by the printed matter manufacturing method according to the present embodiment. As shown in FIG. 4, according to the printed matter manufacturing method of the present embodiment, the first image P1 formed on the transfer-receiving body 10 by the thermal transfer sheet 20 for the transfer-receiving body and the thermal transfer image for the intermediate transfer medium. Since the printed matter P is formed by superimposing the second image P2 formed on the intermediate transfer medium 30 by the sheet 40, the spectral density for each wavelength of the printed matter P is naturally the same as that of the first image P1. 2) and the spectral density of the second image P2 (FIG. 3). Therefore, as shown in FIGS. 2 and 3, the Y1 dye, M1 dye, and C1 dye contained in the dye layers of the respective colors (Y, M, and C) in the thermal transfer sheet 20 for the transfer medium and the thermal transfer dye for the intermediate transfer medium By varying the maximum absorption wavelengths of the Y2 dye, M2 dye, and C2 dye contained in the dye layers of the respective colors (Y, M, C) in the sheet 40, the thermal transfer sheet 20 for the transferred body only or the intermediate transfer medium The troughs in the spectral densities of the respective colors, which would otherwise occur if only the thermal transfer sheet 40 was used, can be filled, and the reproducibility of colors can be remarkably improved.

According to the above example, the finally formed print P contains six dyes: yellow dyes Y1 and Y2, magenta dyes M1 and M2, and cyan dyes C1 and C2. . In transferring the six colors, it is also possible to form six dye layers each containing the six color dyes on a thermal transfer sheet for transfer material, and to form a print using this thermal transfer sheet for transfer material. However, in this case, the material to be transferred is subjected to heat damage from the thermal head six times, which may cause problems such as fusion. It is also possible to provide the six-color dye layers on a thermal transfer sheet for an intermediate transfer medium, and use the intermediate transfer medium to perform transfer onto a transfer-receiving material. As a result of the re-transfer to the transfer-receiving material, the finished print has a 6-layer structure, and a large gap is generated between the 1st and 6th layers, which may blur the image. In order to avoid blurring of the image, it is conceivable to transfer six colors to the receiving layer of one intermediate transfer medium, but in this case the problem of catalyst fading may occur. Further, the thermal transfer sheet for a transfer material is provided with a yellow dye layer containing both yellow dyes Y1 and Y2, a magenta dye layer containing both magenta dyes M1 and M2, and a cyan dye layer containing both cyan dyes C1 and C2. It is also possible to form a printed material using this thermal transfer sheet for a transferred material. Since it cannot be adjusted, even if the valley between the maximum absorption wavelengths of each dye can be filled, the color reproducibility will not be good. On the other hand, according to the method of forming a printed matter according to the present embodiment, in forming a desired printed matter P, as described above, the first image P1 formed directly on the transfer-receiving body 10 and the intermediate transfer medium 30 are interposed between the first image P1 and the intermediate transfer medium 30. and the second image P2 to be formed by the second image P2, which minimizes thermal damage to the transfer medium and minimizes the number of times of retransfer from the intermediate transfer medium, while also having different spectral densities. can be used, the amount of each dye can be adjusted independently according to the amount of heat during transfer, thereby improving color reproducibility.

Here, in the above example, the dyes (Y1, M1, and C1) contained in the respective color dye layers provided on the thermal transfer sheet 20 for transfer medium and the dyes provided on the thermal transfer sheet 40 for intermediate transfer medium Although the dyes (Y2, M2, and C2) contained in each color dye layer are different from each other, in the method of forming a printed matter according to the present embodiment, they do not necessarily have to be different, and the same Dyes may be used, ie Y1=Y2, M1=M2 and C1=C2.

Even in this case, the first image P1 formed on the transfer-receiving body 10 by the transfer-receiving thermal transfer sheet 20 and the intermediate transfer medium thermal transfer sheet 40 can be By superimposing the second image P2 formed on the intermediate transfer medium 30, the print P is formed.

FIG. 5 is a graph showing an example of spectral density for each wavelength of a print P formed by superimposing the first image P1 and the second image.

Here, since the first image P1 and the second image P2 are images formed by dye layers containing the same dye, the spectral densities of both are as shown in FIG. As shown in FIG. 5, the print P completed in step 3 has a higher density.

As described above with specific examples, according to the method for manufacturing a printed matter according to the present embodiment, the first image is formed directly on the transfer-receiving body, and the first image is transferred via the intermediate transfer medium. In order to form a final print with a second image superimposed on the image, the dye contained in the dye layer in the thermal transfer sheet for the transfer material used to form the first image, and the second The combination of dyes contained in the dye layers in the thermal transfer sheet for intermediate transfer medium used for forming an image can be freely selected, and the amount of dye contained in each dye layer can be independently adjusted. Therefore, it is possible to improve the color reproducibility and density of the finally completed printed matter by the method of selection, so to speak, the combination, and further by adjusting the density of the image formed using each dye layer. becomes.
