<< Printed matter of the first embodiment >>
The printed matter according to the first embodiment of the present invention includes a base material, a first print dot on the base material, and a second print dot on the first print dot, and the first print dot is a pattern. And is not erased by rubbing the plastic eraser, and the second printed dot overlaps the first printed dot, thereby concealing the pattern formed by the first printed dot. And can be erased by rubbing a plastic eraser.

  By rubbing the printed matter of the first embodiment of the present invention with a plastic eraser, only the second printed dots are erased, and therefore the pattern by the first printed dots can be easily expressed.

  The plastic eraser used in the present invention contains a plasticizer such as vinyl chloride and a phthalic acid plasticizer, and may conform to the standard of JIS S 6050. Typically, a MONO eraser manufactured by Dragonfly Pencil Co., Ltd. can be used as such a plastic eraser, and in particular, this means one manufactured and sold as of January 1, 2016.

  In addition, rubbing with an eraser may be performed using a paperboard friction tester (manufactured by Kumagaya Rika Kogyo Co., Ltd.) in accordance with JIS P8136. Here, the above eraser (length 10 mm, width 20 mm, thickness 5 mm) is fixed to a friction piece of a testing machine with double-sided tape, and a test sample (a heat-sensitive substrate having a concealing portion) is fixed to a test stand, and a load of 1800 gf. The pressure can be reciprocated until the pattern can be recognized.

  In the printed material according to the first embodiment of the present invention, the printing unit constituting the pattern is configured with dots. Temporarily, both the 1st printing dot and the 2nd printing dot which are used by this invention are continuous 1st printing parts and 2nd printing parts, and a picture is continuous by the 1st printing part. In the case of a pattern having an outline, even if the second printing unit overlaps the first printing unit, the outline of the pattern formed by the first printing unit can be visually confirmed. There is.

  On the other hand, in the printed matter of the first embodiment of the present invention, since the pattern is composed of printing dots, the contour of the pattern is discontinuous, and the second printing dots overlap. It is very difficult to visually observe the outline of the pattern. Therefore, in the printed matter according to the first embodiment of the present invention, it is difficult to observe the pattern until the second print dot is erased.

  In the printed matter of the first embodiment of the present invention, the colors of the first print dots and the second print dots are not particularly limited as long as the outline of the design can be made unclear and the design can be concealed.

  For example, the second print dot may have a color that is a complementary color to the color of the first print dot at a position overlapping the first print dot. In such a printed matter, it is particularly difficult to observe the pattern because the overlapping portion of the printed dots is substantially black until the second printed dots are erased.

  For example, the outline of the pattern may be obscured by making the overlapping portion of the print dots substantially the same color at least near the outline of the pattern constituted by the first print dots.

  In the printed matter according to the first embodiment of the present invention, the area of each dot of the second print dot that overlaps the first print dot is 0.5 times the area of each dot of the first print dot. The above may be 0.6 times or more, 0.8 times or more, 1.0 times or more, 1.2 times or more, 1.5 times or more, 2.0 times or more, and 10.0 times or less. It may be 0 times or less, 3.0 times or less, 1.0 times or less, or 1.5 times or less.

  As long as the advantageous effects of the printed matter according to the first embodiment of the present invention are obtained, the second printed dots may be present on a substrate on which the first printed dots are not present. Only a part of one printing dot may overlap.

  FIG. 1 illustrates a printed matter according to the first embodiment of the present invention. Fig.1 (a) has shown the printed matter of the state which has not erase | eliminated the 2nd printing dot with the eraser. FIG. 1B shows a state in which a part of the second print dots of the printed matter of FIG. 1A is erased with an eraser, and is constituted by the first print dots by erasing the second print dots. The orange pattern is expressed.

  In the printed matter of FIG. 1A, the second print dots are arranged so as to be complementary to the color of each dot of the first print dots at the position where the first print dots and the second print dots overlap. The color is adjusted and printed. As a result, the printed portion of the printed material is a black dot at the position where the first print dot and the second print dot overlap, and the outline of the pattern constituted by the first print dot is very distinguishable. It has become difficult.

  FIG.1 (c) shows the comparative printed matter which has the 1st printing part containing an orange pattern, and the 2nd printing part for concealing the orange pattern which exists on the 1st printing part. Yes. Even in the printed matter of FIG. 1C, the color of the second print unit is adjusted so that it is complementary to the color of the first print unit. However, these print units are dotted. Therefore, the outline of the orange pattern is continuous, and the outline of the pattern can be recognized visually.

  FIG. 2 illustrates the layer structure of the printed material according to the first embodiment of the present invention. This printed material (10) is formed on the ink barrier layer (5) on the substrate (2) and the second printed material. A topcoat layer (4) located on the dots (2) and an ink barrier layer (5) located between the first printed dots and the substrate (3) are provided.

  When the topcoat layer (4) is present in the printed matter (10) of the present invention, the unevenness on the surface of the printed matter (10) can be flattened. By providing the topcoat layer (4) in the printed matter (10) of the present invention, it is possible to make the pattern to be developed after the eraser is abraded more difficult to see in the state before the eraser is abraded.

  When the ink barrier layer (5) is present in the printed matter (10) of the present invention, it is possible to prevent the base material (3) from absorbing the ink used in forming the first printed dots (1). .

  In the printed material according to the second embodiment of the present invention, the printing unit constituting the pattern is configured with dots. Temporarily, both the 1st printing dot and the 2nd printing dot which are used by this invention are continuous 1st printing parts and 2nd printing parts, and a picture is continuous by the 1st printing part. In the case of a pattern having an outline, in order to conceal the continuous outline, it is necessary to print the second print section by completely matching the outline of the portion where the first print section does not exist. Arise. Actually, since it is very difficult to print the second print part by completely matching the outline of the part where the first print part does not exist, the outline of the pattern formed by the first print part May be confirmed visually.

  On the other hand, in the printed matter according to the second embodiment of the present invention, since the pattern is composed of printing dots, the outline of the pattern is discontinuous, thereby completely matching the outline of the first printing dot. In addition, it is not necessary to print the second printing dot. What is necessary is just to print a 2nd printing dot so that a 1st printing dot and a 2nd printing dot cannot be identified substantially in the position where a 1st printing dot does not exist. In such a printed matter according to the second embodiment of the present invention, it is difficult to observe the pattern until the second print dot is erased.

  For example, the second print dot is substantially the same color as the first print dot, so that the first print dot and the second print dot cannot be substantially distinguished from each other. This printing dot can conceal the pattern of the first printing dot. In the case where the first print dot is configured with a plurality of different colors, the second print dot is also configured with a plurality of different colors in accordance with the color scheme of the first print dot, whereby the first print dot The dots and the second print dots cannot be substantially distinguished, and the second print dots can mask the pattern formed by the first print dots.

  The second print dots are preferably printed in a portion where the first print dots do not exist at substantially the same interval as the interval between the first print dots. Thereby, the outline of the pattern by the 1st printing dot can be substantially concealed.

  As long as the advantageous effects of the printed matter according to the second embodiment of the present invention are obtained, the second print dots may be present on the first print dots, and the first print dots You may exist in only a part on a base material in the part which does not exist.

  FIG. 3 illustrates a printed matter according to the second embodiment of the present invention. FIG. 3A shows the printed matter in a state where the second printed dots are not erased by the eraser. FIG. 3B is a state in which a part of the second print dots of the printed matter of FIG. 3A is erased with an eraser, and is constituted by the first print dots by erasing the second print dots. The design of the written characters is manifested.

  In the printed matter of FIG. 3, the second print dots are printed at positions where the first print dots do not exist at substantially the same interval as the interval between the first print dots. Thereby, the outline of the character pattern by the first printing dots is substantially concealed.

  FIG. 4 illustrates the layer structure of the printed material according to the second embodiment of the present invention. The printed material (10) is formed on the first printed dot (1) and the second printed dot (2). A top coat layer (4) positioned, and an ink barrier layer (5) positioned between the first and second printed dots and the substrate (3) are provided.

  When the topcoat layer (4) is present in the printed matter (10) of the present invention, the surface of the printed matter (10) resulting from the thickness of the first printed dots (1) and the second printed dots (2) Can be flattened. By providing the topcoat layer (4) in the printed matter (10) of the present invention, it is possible to make the pattern to be developed after the eraser is abraded more difficult to see in the state before the eraser is abraded.
