Next, a method for manufacturing a printed matter will be described with reference to FIGS. 3 to 5.

First, the thermal transfer sheet 10 and the transferred body 20 are prepared. Next, the heat transfer sheet 10 and the transferred body 20 are superposed so that the color material layer 3 and the receiving layer 23 face each other, and the heat transfer sheet 10 is heated from the back surface layer 9 side by a thermal head of a thermal transfer printer or the like. , The coloring material contained in the coloring material layer 3 is thermally transferred to form an image (not shown) on the receiving layer 23. When the receiving layer 23 is omitted, an image is formed on the surface of the transparent substrate 21.

Following the image formation process, a first white layer transfer process is performed. In the first white layer transfer treatment, the thermal transfer sheet 10 and the transferred body 20 are superposed so that the first white layer 5A and the receiving layer 23 (the image forming surface of the transferred body 20) face each other, and the thermal head is used. The thermal transfer sheet 10 is heated from the back surface layer 9 side, and the first white layer 5A is transferred to a desired region as shown in FIG.

Next, the second white layer transfer treatment is performed. In the second white layer transfer treatment, the thermal transfer sheet 10 and the transferred body 20 are superposed so that the second white layer 5B and the receiving layer 23 (the image forming surface of the transferred body 20) face each other, and the thermal head is used. The thermal transfer sheet 10 is heated from the back surface layer 9 side, and the second white layer 5B is transferred to a desired region as shown in FIG.

A part of the second white layer 5B is transferred onto the first white layer 5A, and the rest is transferred onto the receiving layer 23.

Next, the protective layer 7 of the thermal transfer sheet 10 and the image forming surface of the transferred body 20 are opposed to each other, and the thermal transfer sheet 10 is heated from the back surface layer 9 side with a thermal head, and as shown in FIG. 5, the transferred body 20 is heated. The protective layer 7 is transferred to the entire surface of the printing material 30 to prepare the printed matter 30. The first white layer 5A and the second white layer 5B are covered with the protective layer 7.

The printed matter 30 includes a region R1 in which the first white layer 5A and the second white layer 5B are laminated, a region R2 in which only the second white layer 5B is formed, and a region R3 in which only the first white layer 5A is formed. .. In the printed matter 30, the region R1 in which the first white layer 5A and the second white layer 5B are laminated is the region having the highest concealing property. Further, when the first white layer 5A has a higher concealing property than the second white layer 5B, the region R3 becomes a region having a higher concealing property than the region R2.

For example, in the printed matter 30, the total light transmittance in the region R2 where the second white layer 5B is formed is 75%, the total light transmittance in the region R3 where the first white layer 5A is formed is 45%, and the first white. The total light transmittance in the region R1 in which the layer 5A and the second white layer 5B are laminated is 40%. The total light transmittance can be measured by a method compliant with JIS K-7361 using a haze meter (manufactured by Murakami Color Technology Laboratory, product number; HM-150N).

As described above, according to the present embodiment, a plurality of white concealing regions having different concealing properties can be provided on the printed matter.

Further, when trying to realize the concealing property of the region R1 with one white layer, the thick white layer is transferred from the thermal transfer sheet to the transferred body, the foil breakability of the white layer is lowered, and the tail Pulling can occur and degrade the quality of the print. On the other hand, in the present embodiment, since the thickness of the first white layer 5A and the second white layer 5B is not large, the transfer can be performed with good foil breakability, and the quality of the printed matter 30 can be improved.

Information regarding the hiding power of the first white layer 5A and the second white layer 5B of the thermal transfer sheet 10 may be input in advance to the thermal transfer printer in which the thermal transfer sheet 10 is loaded, or an IC attached to the thermal transfer sheet 10. It may be stored in a tag and read from the IC tag by a reading unit provided in the thermal transfer printer when the thermal transfer sheet 10 is loaded.

The thermal transfer printer has a region forming only the first white layer 5A, a region forming only the second white layer 5B, a first white layer 5A, and a second white so as to have a concealing property assigned according to the image processing. The region where the layer 5B is laminated is determined, and the first white layer 5A and the second white layer 5B are sequentially transferred onto the transferred body.

When the region with high concealment and the region with low concealment are adjacent to each other, the boundary line of the region may be zigzag or wavy instead of straight so that the boundary is not conspicuous. In addition, even if the white layer is transferred in a dot shape and the dot density is gradually changed at the end of the highly concealing region so that the white density changes continuously (smoothly) at the boundary portion. good.

A method for manufacturing a printed matter according to another embodiment will be described with reference to FIGS. 6 to 8. As shown in FIG. 6, the first white layer 5A is transferred to a desired region on a non-transparent substrate 25 such as black.

Next, as shown in FIG. 7, the second white layer 5B is transferred to a desired region on the substrate 25. A part of the second white layer 5B is transferred onto the first white layer 5A, and the rest is transferred onto the base material 25.

Subsequently, as shown in FIG. 8, the receiving layer 23 is transferred onto the substrate 25 so as to cover the first white layer 5A and the second white layer 5B. An image is formed on the receiving layer 23 by using a coloring material such as a dye. The receiving layer 23 on which the image is formed in advance may be transferred onto the base material 25. Then, the protective layer 7 is transferred onto the receiving layer 23 to prepare the printed matter 32.

Also by such a method, it is possible to produce a printed matter 32 provided with a plurality of white concealing regions having different concealing properties.

The heat transfer sheet may be provided with a white layer of a plurality of panels having the same concealing property, and the concealing property may be changed for each region depending on the number of layers of the white layer transferred to the transferred object.

For example, as shown in FIG. 9, the white layer of the first panel of the thermal transfer sheet is used, and the white layer 5-1 of the first layer is transferred to a desired region on the transferred body 20. The second panel white layer of the thermal transfer sheet is used to transfer the second white layer 5_2 to a desired region on the transfer subject 20. Similarly, the white layer of the third panel of the thermal transfer sheet is used to transfer the third white layer 5_3 to a desired region on the transfer subject 20.

As a result, the printed matter 34 including a plurality of regions having different numbers of laminated white layers can be produced. Regions with different numbers of white layers have different hiding properties from each other.

When the region to transfer the white layer is small, the white layer may be transferred a plurality of times while changing the heating region of the white layer of one panel of the thermal transfer sheet, and may be laminated on the transferred object. For example, as shown in FIG. 10, in the white layer 5 for one panel, the heating region is shifted along the longitudinal direction of the thermal transfer sheet 10 for each transfer. As a result, the panel can be used efficiently.
