From the latent image information printing section that prints the selected latent image information, and the micro characters that mean the date that is always invisible when printed at the corners of the paper sheet and is visible by enlargement by the enlargement means It is effective for prevention of counterfeiting and falsification of printed paper sheets because it has both a function to guarantee the originality of printed paper sheets and a function to specify the time of existence. It is possible to realize and provide a counterfeit-proof printing paper sheet.

  According to the invention described in claim 3, in the invention described in claim 1 or 2, the latent image information of the latent image information printing unit is capable of visualizing character information such as copying and copying. By visualization of character information such as copying and copying, it is possible to realize and provide a forgery-preventing printing paper sheet that can exhibit the function of ensuring the originality of the printing paper sheet.

  According to the invention described in claim 4, in the device described in any one of claims 1 to 3, the original collaterality of the various forms such as contracts, estimates, invoices, receipts, etc. It is possible to realize and provide forgery-preventing printing paper sheets that have the above functions and are extremely useful for preventing counterfeiting / tampering of forms.

FIG. 1 is a plan view of an anti-counterfeit printing paper sheet according to an embodiment of the present invention. FIG. 2 is an explanatory diagram showing the existence area of the latent image information printing unit on which the latent image information is printed on the forgery-preventing printing paper sheet according to the present embodiment by a dotted line rectangle. FIG. 3 is an explanatory diagram showing the visible image information based on the latent image information that is expressed by the copying process of the anti-counterfeit printing paper sheet according to the present embodiment. FIG. 4 is an explanatory diagram showing an enlarged visual state of minute characters printed on the forgery-preventing printing paper sheet according to the present embodiment.

  The present invention has a printing function for preventing counterfeiting, which has both a function of guaranteeing originality and a function for specifying the time of existence (in other words, a function for guaranteeing the existence certificate), which is effective for preventing counterfeiting / tampering of printing paper. The purpose is to provide a latent image selected from any character, symbol, pattern, or image that is not visible at all times and printed by a copier. A latent image information printing section on which image information is printed, and a minute character composed of a micro character indicating a date that is not visible at all times and is visible by enlargement by a magnifying means, which is printed at the corner of the paper sheet. This is realized by a configuration having a printed minute character printing unit.

  Hereinafter, a forgery-preventing printing paper sheet according to an embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 4, the forgery-preventing printing paper sheet 1 according to this embodiment includes a paper sheet 1 a having a predetermined size (for example, A4 size, B5 size, etc.) and most of the paper surface of the paper sheet 1 a. For example, the character information printing section 2 and the paper sheet 1a, for example, the upper right corner and the lower left corner of the paper sheet 1a, which are not always visible and can be visually recognized by the enlargement process by a magnifying means such as a magnifying glass H30-8-1, etc.) The micro character printing unit 4 in which micro characters 4a made of micro characters are printed by publicly known means, and printed at any place on the paper sheet 1a is always invisible and not shown. Latent image information printing in which latent image information (for example, “copy” characters as shown in FIG. 3) 5a selected from arbitrary characters, symbols, patterns, and images to be visualized by copying by a copying machine is printed by known means. And having part 5 That.

  The dotted line rectangle shown in FIG. 2 indicates the existence area 5b of the latent image information printing unit 5 on the paper sheet 1a.

  The minute characters 4a of the minute character printing unit 4 are printed with micro characters in the upper right corner, the lower left corner, etc. for each production lot of the paper sheets 1a and so as not to disturb the printing contents for the printing unit 2 such as character information. Thus, the date of manufacture of the anti-counterfeit printing paper sheet 1, that is, the start date of existence can be specified, and at least the previous anti-counterfeit printing paper sheet 1 has not been proved to exist ( In other words, a function that guarantees the existence certificate is possible, and as a result, when the forged counterfeit printing paper 1 is used as a contract, it is useful for preventing counterfeiting / tampering of the contract, etc. is there.

  The micro characters 4a are ultra-fine characters and are therefore printed with characters that are difficult to read with the naked eye. In the original anti-counterfeit printing paper 1, the micro characters can be clearly read by magnifying the micro characters with a magnifying glass (loupe). Even if copied by a copying machine, it cannot be reproduced clearly.

  As the minute characters 4a, for example, “H30-8-1 (meaning August 1, 2018)” is repeatedly printed several times in accordance with the date of manufacture of the anti-counterfeit printing paper 1. An example can be given, but the printed content is not particularly limited.

  The minute character printing unit 4 is used in an image such as a common food traceability code (manufacturing date, manufacturing factory, etc.).

  The printing of the latent image information 5a of the latent image information printing unit 5 is a technique for embedding a latent image by printing a combination of fine points exceeding the resolution of the scanner function of the copying machine and rough points that appear to have the same density, Here, since a thin point cannot be read as a point, it disappears in the middle of image processing, and as a result, a technique is used in which only a rough point remains and an embedded latent image appears.

  That is, as the characters of the latent image information 5a, for example, if characters such as “copy” and “copy” are embedded, the characters are visible as a visible image when copied by a copying machine. In the case where a contract is created using a plurality of sheets of anti-counterfeit printing paper 1 and a part of the contract is replaced with a paper that does not include the latent image information printing unit 5 and has been counterfeited / tampered Can quickly determine that it is a fake contract including a paper sheet that does not include the latent image information printing unit 5, whereby the forgery-preventing printing paper sheet 1 is effective as a guarantee of originality, It has a certain effect as a deterrent against fraud and tampering.

  As the latent image information 5a of the latent image information printing section 5, a symbol, a pattern, a desired image, etc. can be selected in addition to characters, and is not particularly limited.

The anti-counterfeit printing paper sheet 1 effectively demonstrates the function of specifying the existence period of contracts, estimates, invoices, receipts, etc., and the originality guarantee function, and is extremely useful for preventing these counterfeits and tampering. It is beneficial.
In any case, according to the forgery-preventing printing paper sheet 1 according to the present invention, as described above, the latent image information printing unit that prints the latent image information, and the minute characters that are printed with the minute characters that are the micro characters. With the printing unit, the function of ensuring the originality can be exhibited, and furthermore, the manufacturing date of the anti-counterfeit printing paper leaf 1 with the micro character printing unit that prints the micro characters composed of the micro characters, that is, The existence start time can be specified, and the non-existence proof function (in other words, the function to ensure the existence proof) that the forgery prevention printing paper sheet 1 did not exist at least before that can be exhibited.

  The anti-counterfeit printing paper sheet of the present invention has functions to secure the originality of various forms such as contracts, estimates, invoices, receipts, etc., and functions to specify the time of existence, and to prevent forgery and tampering of various forms. Can be suitably used.
