Abstract
The invention discloses a novel secure file, which comprises two layers or three layers of patterns. When the secure file comprises two layers of patterns, the bottom layer is subjected to offset printing, and the surface layer is subjected to letterpress printing; the bottom layer of the secure file gives out monochromatic light with the same color as that of the bottom layer under the excitation of infrared laser, while the surface layer gives out light visible to human eyes under the excitation of the infrared laser. When the secure file comprises three layers of patterns, both the bottom layer and the surface layer are subjected to offset printing, and the middle layer is subjected to letterpress printing; and the bottom layer or the surface layer of the secure file gives out monochromatic light with the same color as that of the bottom layer or the surface layer correspondingly under the excitation of the infrared laser. The novel secure file implements an infrared up-conversion fluorescent material by combining the offset printing and letterpress printing ways with the light-emitting characteristics of infrared up-conversion composite white light, gives out two kinds of different visible lights recognizable by human eyes under the excitation of the infrared light, and is difficult to imitate, strongly elusive and easy to distinguish anti-counterfeiting effects.
Description
Technical field
The present invention relates to field of anti-counterfeit technology, be specifically related to a kind of secure file.
Background technology
Chinese patent CN102205761A disclosed in 2011 relates to a kind of secure file with optic response feature, described secure file contains the combination anti-fake material of one or more rare earth compounds, this secure file is by after ultraviolet excitation, can infrared light be launched, and disclose detection and whether there is this anti-counterfeiting characteristic method hereof.This invention has the strong feature of false proof disguise, but anti-counterfeiting characteristic needs specific detecting instrument to identify.
The application in 2008 of German federal printing Co., Ltd, Chinese patent CN101678696A disclosed in 2011 relates to a kind of secure file with safety element and/or value document, and its safety element comprises at least two different being selected from and comprises following set of security features as hologram, laser engraving, printing floral designs, fluorescence floral designs, luminous flower-pattern pattern, diffraction floral designs and photochromatic printing ink floral designs.Each security feature of secure file and/or value document has graphic structure accordingly, wherein different security feature graphic structure connects in the mode be arranged in the different layers of secure file and/or value document or identical layer each other on figure, or superimposed in mode in the different layers being arranged in secure file and/or value document each other, and wherein different security feature graphic structures forms the overall expression of figure.This technology is only the simple superposition of different security feature, and at least comprises two kinds of security features due to it, therefore it realizes needing higher cost.
The Chinese patent CN102164752A of Delalu International Co., Ltd of Britain relates to improvement in secure file and a kind of method for making this secure file.The secure file be made up of cellulosic security substrate comprises at least one watermark and background wire mark pattern.Its at least one watermark comprise at least one can machine detect pattern, and described at least one can the element that repeats with comprising series of rules of pattern that detects of machine, wherein the pitch of the element of pattern is chosen as different from the pitch of the background wire mark pattern be formed in substrate and for every centimetre (5) in the scope of (100) individual element.The antifalse effect of this technology is not easy to be identified by human eye, needs a set of specific associated detector and software.
The Chinese patent CN1993714A of Giesecke & Devrient GmbH relates to a kind of data medium, particularly value document is as banknote, identification card etc., it has safe unit, and this safe unit shows printing images and laser-marking overlapping with printing images at least in part.Safe unit also shows the laser overlapped with printing images at least in part and revises district, and its recording laser identifies, and in laser amendment district and printing images overlapping region, the visual appearance of printing images is revised by laser beam effect.The costs rather expensive of the realization of this technology.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of secure file, this secure file have not easily be imitated, the feature that disguised strong and antifalse effect easily identifies, cost is low.
The technical scheme realizing objects of the present invention is as follows:
A kind of secure file, this secure file is made up of two-layer or three layer patterns: (1) is if be made up of two-layer pattern, then bottom is offset printing, surface layer is the printing of convex print, this secure file bottom one side is under infrared laser excites, send the monochromatic light identical with primary colour, surface layer one side then under infrared laser excites, then sends the visible white light of human eye; (2) if be made up of three layer patterns, then bottom and surface layer are offset printing, and intermediate layer is the printing of convex print, under the bottom of this secure file or surface layer infrared laser shooting condition, correspondingly respectively send the monochromatic light identical with bottom or surface layer color.
Wherein, convex print printed layers color in secure file is white or colourless, convex print printed layers printing area is not less than 1 square millimeter, be preferably more than 0.25 square centimeter, convex print printed layers is at least containing a kind of fluorescent material, under the infrared laser shooting condition that this fluorescent material (is preferably 980nm) within the scope of 700-1500nm, send macroscopic CIE-X and the CIE-Y value of people between 0.3-0.4, preferred CIE-X and CIE-Y value is the white light of 0.35.Fluorescent material described in secure file is fluoride, one or more in sulfide, oxyhalide and composite oxides, and above-claimed cpd is at least containing two or more rare earth element, is preferably Ho, Er, Pr, Tm, Ce, Eu, Nd and Yb.
Offset printing layer in described secure file can be the arbitrary color except black, is preferably red, blue, green and yellow.
Secure file of the present invention, prints two-layer or three layers of pattern formed by by offset printing and convex print, and its bottom and surface layer, under infrared laser excites, send monochromatic light respectively with recombined white light or send the monochromatic light identical with surface layer color with bottom respectively.Compared with the prior art, present invention achieves a kind of infrared up conversion fluorescent material, under infrared ray excited, send two kinds of people's naked eyes identifiable design different visible light, have more not easily be imitated, disguised stronger feature, meanwhile, detector of the present invention adopts general infrared laser, available identifying by naked eye, anti-counterfeit recognition effect is apparent.
