Abstract
The invention relates to an anti-counterfeiting printing method, which includes steps: firstly, selecting two types of ink different in infrared up-conversion characteristic and ultraviolet fluorescence characteristic to form paired ink, wherein the ink with the infrared up-conversion characteristic has the infrared up-conversion characteristic at set waveband in an infrared area, the ink with the ultraviolet fluorescence characteristic is ultraviolet fluorescent ink which has the ultraviolet fluorescence characteristic at set waveband in an ultraviolet area or is more than one type of ultraviolet fluorescent pairing ink, and the color of the ultraviolet fluorescent ink forming the paired ink at the waveband in the ultraviolet area is evidently different from that of the ultraviolet fluorescent ink under visible light; and secondly, printing anti-counterfeiting patterns serving as anti-counterfeiting information on a same printing stock carrier. The anti-counterfeiting printing method which is a technical way for implementing composite counterfeiting prevention is provided to meet the high requirements of the prior art on anti-counterfeiting technique, the anti-counterfeiting information has photo-discoloration characteristic under specific light irradiation.
Description
Technical field
The present invention relates to field of anti-counterfeit technology, specifically about utilizing infrared upper conversion ink and fluoresent printing ink combinations of pairs to realize false proof method, to provide anti-counterfeiting technology content higher anti-counterfeit printed.
Background technology
In anti-counterfeit printing fields such as money, marketable securities and trade marks, anti-forgery ink is to apply products similar very widely, in order to improve the anti-counterfeiting technology content of anti-fake product, increase and copy difficulty and cost, research and develop new anti-forgery ink and anti-counterfeiting technology and method very important.At present, fluoresent printing ink (some data is also ultraviolet ink) is in ink, to add corresponding visible fluorescence compound to make, excite and send the special ink of visible ray with UV-irradiation, its anti-counterfeiting characteristic is: printing product be cannot see fluorescence under ordinary ray, under ultraviolet ray, can send glittering fluorescence.Infrared up-conversion material is that a kind of Infrared irradiation excites the lower luminescent material that can send visible ray, is converted into the material of visible ray by infrared light; Ink prepared by application infrared up-conversion material is in infrared upper conversion ink, and its anti-counterfeiting characteristic is: under infrared ray excited, can send visible ray.Fluoresent printing ink and these two kinds of ink of infrared upper conversion ink are applied to false proof field existing bibliographical information both at home and abroad, although also can reach false proof,
But along with the further raising that society requires anti-counterfeiting technology, need to provide in a hurry one can show colourful pattern change, the method can again with composite anti-fake function promotes false proof level.
Summary of the invention
In order to adapt to the high request of prior art to anti-counterfeiting technology, the invention provides a kind of anti-counterfeiting printing method, by utilizing infrared upper conversion anti-counterfeiting characteristic ink and the pairing of Ultraluminescence anti-counterfeiting characteristic ink that a kind of technological means that realizes composite anti-fake is provided, carrying anti-counterfeiting information, under specific irradiation, has phototropic characteristic.
Technical solution of the present invention:
A kind of anti-counterfeiting printing method, its special character is: the method comprises the following steps:
1] select all not identical two class ink composition pairing ink of infrared upper converting characteristic and Ultraluminescence feature;
Described have infrared upper converting characteristic ink be a kind of under the setting wave band of infrared light region, have change on conversion performance infrared on infrared ink or more than one infrared on conversion pairing ink, the color that wherein the infrared upper conversion ink in composition pairing ink manifests under infrared light region wave band is obviously different from the color manifesting under visible ray condition;
Described to have Ultraluminescence feature ink be under a kind of wave band of setting in ultraviolet light region, to have the fluoresent printing ink of Ultraluminescence performance or more than one Ultraluminescence pairing ink, and the color that wherein fluoresent printing ink in composition pairing ink manifests under the wave band of ultraviolet light region is obviously different from the color manifesting under visible ray condition;
2] use respectively step 1] select two class ink on same stock carrier, print the security pattern that can be used as anti-counterfeiting information.
Two class ink are applied to the different piece of same security pattern.
Different types of ink is applied to two or more parts that same security pattern joins; Or be applied to two or more tangent parts of same pattern.
In visible region, visible color is the synthetic patterns of multiple single colour cells to above-mentioned pairing ink.
Also comprise step 3] checking security pattern:
3.1] adopt nature radiation of visible light security pattern, obtain master pattern;
3.2] adopt Infrared irradiation security pattern, obtain the first pattern;
3.3] adopt UV-irradiation security pattern, obtain the second pattern;
3.4] adopt infrared light and ultraviolet light jointly to irradiate security pattern, obtain the 3rd pattern;
3.5] judge the true and false:
If the first pattern, the second pattern and the 3rd pattern are completely different from master pattern, anti-counterfeiting printing product is true;
If the first pattern, the second pattern and the 3rd pattern master pattern exist something in common, anti-counterfeiting printing product is false.
Under the setting wave band of infrared light region:
The ink in pairing ink with infrared upper conversion performance can manifest solid color;
Or the ink with infrared upper conversion performance is that two or more infrared upper conversion ink combinations of pairs is used, under the setting wave band of infrared light region, all there are one or more solid colors;
Under the setting wave band in ultraviolet light region:
The ink in pairing ink with Ultraluminescence performance can manifest solid color;
Or the ink with Ultraluminescence performance be two or more fluoresent printing ink combinations of pairs use, under the setting wave band in ultraviolet light region, all there are one or more solid colors.
Above-mentioned pairing ink is one or more the mixing in gravure ink, letterpress printing ink, offset ink, ink-jet or screen printing ink.
Above-mentioned stock is paper substrate, polymeric material, glass or metal material.
The present invention has advantages of:
The present invention adopts the variation combination of four class patterns (under visible ray, under ultraviolet light, under infrared light, ultraviolet with under infrared associating) to improve simple infrared upper converting characteristic or Ultraluminescence feature anti-fake machine reading level, thereby effectively realize and utilize machine-readable composite anti-fake object, also the combinations of patterns effect that has improved printing product, has improved antifalse effect simultaneously.
