Abstract
The invention relates to a near-infrared invisible anti-fake printing method. Invisible infrared up-conversion red, invisible infrared up-conversion green and invisible infrared up-conversion blue are used as RGB printing ink. An ordinary offset printing device, an ordinary gravure device and the like are used for overprinting to achieve the effect that a printed pattern cannot be seen by naked eyes. Under near-infrared light, a colorful pattern achieving conversion luminescence of red, green, blue, cyan, magenta, yellow and white is formed. The near-infrared invisible anti-fake printing method can be used for anti-fake printing of labels.
Description
Technical field
The present invention relates to the printing process of a kind of near-infrared concealed anti-false, belong to anti-counterfeit printing field.
Background technology
Hide information and hidden pattern are category features of anti-counterfeiting technology, it utilizes the invisibility of printing element, under some light source, show pigment simultaneously, thus reach the effect of concealed anti-false, what current application was more is colorless fluorescent printing, be everlasting in the marketable securities such as bill and use, but usually use comparatively dull, at present some bills also occur realizing color fluorescence effect by the colorless fluorescent chromatography of multiple emission spectrum, as invisible by using colorless fluorescent combined printing to obtain naked eyes, visible multicolour pattern under ultraviolet fluorescent lamp.The anti-counterfeit printed of multicolour pattern is presented there are no under IR.
Summary of the invention
It is invisible that the technical problem to be solved in the present invention is to provide a kind of naked eyes, presents the method for multicolour pattern true to nature under near-infrared light source.The application of expanding anti-fake technology.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: it be adopt that stealthy infrared up conversion is red, infrared up conversion is green, the blue three sections of ink of infrared up conversion are as the ink of RGB tri-look, adopt common offset printing, the printing equipment chromatographys such as gravure, it is invisible that printed matter reaches naked eyes, have under near infrared light and send redness simultaneously, green, blue, cyan, magenta, the multicolour pattern of yellow and white transition luminescence.
Adopt common offset press or gravure equipment, adopt colourless infrared up conversion ink, according to printing equipment, upper ink of changing can be offset ink, gravure ink system.Main pigments in ink is colourless infrared up conversion pigment, and its utilizing emitted light is respectively red, green, blue.
Utilize three sections of specific ink of the present invention, through the printed matter that chromatography obtains, there are naked eyes invisible, multicolour pattern true to nature as seen under near-infrared lamp, the pattern that will realize as required is decomposed into RGB tri-pieces of versions, by red for the infrared up conversion of stealth, infrared up conversion is green, the blue three sections of ink of infrared up conversion are printed on base material successively, namely obtains anti-counterfeiting printing product.
Detailed description of the invention
Further illustrate below in conjunction with embodiment.By red for the infrared up conversion of stealth offset ink, the green offset ink of infrared up conversion, the blue offset ink of infrared up conversion on Heidelberg four colour offset press successively chromatography realize the pattern that sets, namely naked eyes are obtained invisible, under near infrared light, the false proof specimen page of visible color pattern, can be used for the anti-counterfeit printing of trade mark.
By red for the infrared up conversion of stealth gravure ink, the green gravure ink of infrared up conversion, the blue gravure ink of infrared up conversion on loose moral ten look intaglio printing press successively chromatography realize the pattern that sets, namely naked eyes are obtained invisible, under near infrared light, the false proof specimen page of visible multicolour pattern, can be used for the anti-counterfeit printing of trade mark.
Claims (3)
1. near-infrared concealed anti-false printing process, it be adopt that stealthy infrared up conversion is red, infrared up conversion is green, the blue three sections of ink of infrared up conversion are as the trichromatic ink of RGB, adopt common offset printing, the printing equipment chromatographys such as gravure, reach naked eyes invisible, have under near infrared light and send redness simultaneously, green, blue, cyan, magenta, the multicolour pattern of yellow and white transition luminescence.
2. printing process according to claim 1, is characterized by: ink used is colourless infrared up conversion ink.
3. ink according to claim 1, is characterized in that: according to printing equipment, and upper ink of changing can be offset ink, gravure ink system; Main pigments in ink is colourless infrared up conversion pigment, and its utilizing emitted light is respectively red, green, blue.
