Description

  The present invention relates to a special printed matter obtained by performing a special printing process on the surface of a base sheet, and in particular, configured to display hidden information by rubbing the surface using a metal piece such as a coin. The present invention relates to a scratch printed material and a manufacturing method thereof.

  Conventionally, scratch printing technology has been applied to instant lotteries (certificates with a prize), media for product sales promotion, and the like. A general scratch print first prints all information including characters (or designs) to be concealed on the surface of a base sheet made of paper or synthetic resin, and then conceals the printed information. It is manufactured by a method in which a masking layer having peelability is partially formed on a printing surface so as to cover a portion to be covered.

  The conventional general scratch printed matter has a problem that when the scratching is performed, the concealing layer is scraped off from the surface of the base sheet, resulting in “scraping”. There are also scratch printed materials that are devised so as not to cause such shavings, but the use of special paper often leads to high manufacturing costs, and in this case, it is necessary to be able to manufacture at low cost. It is very difficult to apply to instant lotteries and merchandise promotion cards, which is not practical, and the density of characters and numbers expressed by scratches is low, making it difficult to read is there.

  The present invention has been made to solve such problems in the prior art, and can be scratched without causing shavings and manufactured at a lower cost than conventional general scratch prints. An object of the present invention is to provide a scratch printed material that can be printed and a method for manufacturing the same.

  In the method for producing a scratch print of the present invention, information to be concealed is printed on the surface of the base sheet using an ink containing titanium oxide as a pigment, and two or more colors (more preferably, three or more colors) are printed thereon. The color camouflage design is printed. In addition, it is preferable to print concealment information, print a transparent camouflage pattern with a varnish on it, and print a color camouflage pattern of two or more colors on it. The color of the ink is preferably white, and further, confirmation means (for example, a solid band) using white ink is formed along any edge of the base sheet or partially in the vicinity of any edge. ) Is preferably printed.

  In addition, the scratch printed matter of the present invention has two or more (more preferably three or more) color camouflage patterns or a transparent camouflage with a varnish agent on a printing surface formed using an ink containing titanium oxide as a pigment. It is characterized by printing a design and two or more color camouflage designs.

  The scratch printed matter of the present invention can be expected to have an effect that no shaving is generated when scratching. Further, according to the method for producing a scratch printed material of the present invention, the work time required for the production can be greatly shortened (one fifth of the work time in the conventional general scratch printed material). Therefore, the present invention can be applied to an extremely short delivery date (for example, a flyer advertisement).

  Furthermore, according to the manufacturing method of the present invention, the manufacturing cost of the scratch print can be suppressed. More specifically, in order to form a concealing layer having peelability, it is necessary to transport a semi-finished product printed in a printing factory to a silk screen factory in order to form a conventional scratch print. However, since the scratch printed matter of the present invention can be completed in the printing factory, no extra transportation cost is generated. Therefore, it can be manufactured at a lower cost than a conventional general scratch print.

  In addition, the scratch printed matter of the present invention can naturally conceal specific information before scratching, and can clearly display the concealed information after scratching. It has the necessary functions as a scratch print.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory diagram of a “scratch printed matter manufacturing method” according to the first embodiment of the present invention. First, as shown in (1), printing is performed on the surface of a white base sheet 2 (made of paper or synthetic resin) by an offset printing machine. For the portion other than the information to be concealed (display portion A), any color ink may be used, and the background color can be any color scheme, but the information to be concealed (concealment) For part B), printing is performed using a white ink containing titanium oxide as a pigment, and in principle, printing is not performed on the background.

  In this state, it is obvious that the print information can be clearly seen for the display portion A, but for the concealment portion B, the background (ground color of the base material sheet 2) and the color of the ink used. Are coincident (both are white) and cannot be easily visually recognized. However, even if they are the same color, the light reflection is slightly different between where printing is performed and where printing is not performed, so concealment can be achieved by changing the line-of-sight angle or light incident angle. The print information in the part B may be visible.

  Therefore, in order to avoid such inconvenience, a color camouflage pattern C is printed on the upper layer of the concealed portion B as shown in FIG. As shown in the figure, the color camouflage pattern C includes two or more kinds of colors (or line drawings, other patterns) such as circles, triangles, and quadrilaterals generated by ink not containing titanium oxide (note that , Red and blue colors are preferred), and those obtained by randomly superimposing them in a collage style are used. However, it is not limited to this, such as a mysterious camouflage pattern, a pattern that can expect the effect of separating the viewer's attention and observation power from concealed letters and numbers by hue perspective, etc. Color camouflage patterns other than those described above may be used as long as the print information in the concealment portion B can be in a state that is difficult to visually recognize.

  The printed matter produced in this way is scratched (rubbed on the surface of the concealed portion B) with a small piece made of metal such as coins (metal softer than titanium), as shown in FIG. Thus, the concealed print information D can be clearly seen, and scratching can be performed without causing shavings.

  This point will be described more specifically. Since the concealed portion B is printed using an ink containing titanium oxide, fine particles of titanium oxide adhere to the surface of the substrate sheet 2 on which the printing has been performed. When scratching with a small piece of metal softer than titanium, the metal piece is partly scraped off by fine particles of titanium oxide, which remains on the printed surface and is colored. Will be. As a result, the concealment information appears and becomes visible. And since this printed matter does not have a structure that forms a peelable concealing layer as in the prior art, no scratches are generated at the time of scratching.

  In addition, as the base material sheet 2, it is preferable to use high-quality paper (non-coated paper), coated paper, mat coated paper, and the like. For the concealment portion B, when using high quality paper as the base sheet 2, the dot percentage is in the range of 30 to 40%, and when using coated paper or matte coated paper, it is in the range of 20 to 30%. It is preferable to print by setting. For the color camouflage pattern C, printing is performed by setting the dot percentage in the range of 5 to 20% in the case of fine paper and in the range of 3 to 15% in the case of coated paper or matte coated paper. It is preferable. If it is out of these ranges, the concealing effect before scratching may not be obtained sufficiently.

  Further, as the ink (white ink containing titanium oxide as a pigment) used for printing the concealment part B, it is preferable to use a titanium oxide content of 35 to 80% by weight (general ones) By using such ink, the concealment information after scratching can be clearly expressed. In addition, when an ink having a titanium oxide content of 55 to 65% by weight is used, the concealment information can be displayed more effectively.

  Moreover, it is preferable that the white ink used for printing the concealed portion B is mixed with a film reinforcing agent in the range of 1 to 3% by weight in advance and kneaded. In this case, since the fixability of the ink (printing layer) with respect to the base sheet 2 can be improved, choking can be suitably avoided, and even if the surface is rubbed with a metal piece, a printing layer with white ink is formed. As a result, it does not easily fall off from the base sheet 2, and as a result, even after the concealment information has been exposed by scratching, the surface is rubbed with an eraser or the like and remains on the printing surface. By removing the metal powder that is present, it is possible to return to the original concealed state (scratchable state). Then, the “expression of concealment information by scratch” and “return to concealment” can be repeatedly executed about 3 to 4 times.

  The ink used for printing the color camouflage pattern C is preferably mixed with a film reinforcing agent in the range of 1 to 3% by weight and kneaded in advance. The concealment portion B usually has a matte finish due to the fact that the white ink used contains a large amount of titanium oxide as a pigment, but the portion printed with an ink other than the white ink is basically In this case, the gloss gap causes the printing information in the concealed portion B to be visually recognized due to the gloss gap. However, when a film reinforcing agent is mixed in the ink used for printing the color camouflage pattern C, The finish of the color camouflage pattern C is somewhat matte, and the gloss cap with the concealed portion B is reduced, so that a more favorable concealing effect is obtained.

  Next, a second embodiment of the present invention will be described. FIG. 2 is an explanatory diagram of a “scratch printed matter manufacturing method” according to the second embodiment of the present invention. First, as shown in (1), printing is performed on the surface of a white base sheet 2 (made of paper or synthetic resin) by an offset printing machine. This point is the same as in the first embodiment. That is, the display portion A has an arbitrary color scheme, and the concealed portion B is printed using white ink containing titanium oxide as a pigment, and printing is not performed on the background in principle.

  Next, as shown in FIG. 2 (2), a transparent camouflage pattern E is printed on the concealed portion B with a varnish. As the transparent camouflage pattern E, as shown in the figure, a kanji character having a large number of strokes (preferably 20 strokes or more), a line drawing, other symbols, or a combination thereof is used. Moreover, as a varnish used for printing, it is preferable to use what mixed "mat varnish" and "gloss varnish" in the ratio of 1: 1, and also to those mixtures (6 (+/- 1) weight part). On the other hand, it is preferable to use one added with white ink (1 part by weight) having a titanium oxide content of 50% by weight.

  Then, as shown in FIG. 2 (3), a color camouflage pattern C is printed on the upper layer of the transparent camouflage pattern E. As the color camouflage pattern C, as in the first embodiment, two or more kinds of colors generated by using an ink that does not contain titanium oxide as a geometric figure (or a line drawing or other pattern) such as a circle, triangle, or quadrangle. Use the ones that are randomly layered in a collage style.

  The printed matter produced in this manner can be made into a state where the concealed print information D can be clearly seen as shown in FIG. 2 (4) by scratching with a small piece of metal. In addition, scratching can be performed without causing shavings. Moreover, by printing the transparent camouflage pattern E by the varnish agent, the light reflection condition on the surface becomes more complicated than the printed matter of the first embodiment, and the printing information of the concealed portion B is changed due to the difference in the light reflection condition. It is possible to suitably avoid the demerit of exposing. As a result, even when a sheet other than high-quality paper (non-coated paper), coated paper, and mat coated paper is used as the base sheet 2, a sufficient concealing effect can be expected.

  In both the first embodiment and the second embodiment described above, the information of the concealment portion B is printed with characters having a size within a height of 18 mm × a width of 18 mm and a thickness of 0.8 mm or less. It is preferable. This is because, when a character exceeding this size or thickness is used, there is a high possibility that the print information of the concealed portion B will be exposed in advance.

  In addition, as described above, the white ink used for printing the concealment portion B contains a large amount of titanium oxide, and therefore has sufficient printability in terms of fluidity, transferability, and the like. It is difficult to say, and unevenness of the print finish occurs, and there is a concern that the print suitability may be lowered. For this reason, after printing, inspection work for excluding products that are not properly printed becomes important. However, since the finished state of the concealment portion B matches the background color (the color of the base sheet 2), there is a problem that it is difficult to visually recognize.

  Therefore, as shown in FIG. 3, a solid having a width of 20 mm or more with white ink along any edge (for example, the holding side) of the base sheet 2 (or partially in the vicinity of any edge). If the band 3 (confirming means) is printed, as shown in FIG. 4, the prints that have been printed with the white ink are overlapped with their directions aligned, shifted slightly in an oblique direction, and then the solid band 3 Inspection can be easily performed by rubbing the end 3a of the metal plate with a metal piece and visually checking the coloring state.
