Abstract
The invention discloses a hidden readable image and manufacturing method thereof. The said hidden readable image has at least two marks. The bottom mark is an infrared absorbing material absorbed in an infrared light spectral region and the said infrared absorbing material is evidently absorbed at the nm range of 1000 to 2500 and invisible light spectral region and at 800 nm. The upper mark is infrared non-absorbing material which is absorbed at the visible light spectral region and at about 800 nm, and not absorbed at the range of 1000 to 2500 nm. The offset printing for infrared absorbing material sets number, design or code as shade in advance. And then the infrared non-absorbing material is overprinted on the shade using offset printing, silk screen or carving mark technique. The aim to hiding information can be obtained. Finally, the hidden information can be read using infrared radiation overprinting area.
Description
Technical field
The present invention relates to a kind of anti-counterfeiting image and preparation method thereof, relate in particular to a kind of cryptical readable image and preparation method thereof.
Background technology
Cryptical readable image is employed in anti-counterfeit printing, is that filter reads hiding picture and text as what adopt among the Chinese patent application 03153189.X " hiding the method for making of picture and text "; What China Patent No. 99800098.1 " valuable document " adopted is that 2 kinds of rare earth metal luminescent substances reach the purpose of hiding picture and text; The mark substance of Chinese patent application number 02819632.5 " adopting the marketable securities and the anti-fake mark of mark substance " employing is an organic substance, in 1000 to 2500 nanometer range, has obvious absorption, but do not have obvious absorption with 800 nanometers in the visible light district, mark substance adopts organic substance to increase the cost of manufacture of hidden image.
Infrared absorbing material and infrared permeation material have been used to false proof field, but they generally only are taken as infrared pairing use.
Infrared absorbing material and infrared permeation material generally all use mode of printing of the same race to print in the existing false proof field, and infrared absorbing material and infrared permeation material are positioned on same aspect/plane like this, can not satisfy the purpose that hides Info.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of cryptical readable image; Another object of the present invention is to provide the preparation method of hidden image, this method profit finally reaches the purpose that hides Info by using infrared absorbing material and infrared permeation material of the same race or the xenogenesis mode of printing is printed on the different aspects/plane of stock.
The technical scheme that realizes objects of the present invention is as follows:
A kind of cryptical readable image, at least have two kinds of traces, described bottom trace is a kind of systemic infrared absorbing material in the infrared light spectrum district that has, this infrared absorbing material has obvious absorption in 1000 to 2500 nanometer range, and in the visible light district, having obvious absorption equally with 800 nanometers, described infrared absorbing material is the inorganic substances carbon black; Described upper strata trace is infrared non-absorbing material, this infrared non-absorbing material absorbs in visible spectrum and under about 800 nanometers, but do not absorb in 1000 to 2500nm scopes, described infrared non-absorbing material is the Paliogen that BASF AG produces
SCHWARZ S0084; With these 2 kinds of materials respectively by weight percentage composition 0.1%-30% make printing ink, promptly make INFRARED ABSORPTION printing ink and infrared non-absorption printing ink respectively, in printing process, use the certain image of INFRARED ABSORPTION ink printing immediately earlier, this image is and hides Info, adopt infrared non-absorption printing ink that the hiding Info of INFRARED ABSORPTION ink printing of printing just now covered printing immediately, reach the sightless purpose of the naked eyes that hide Info.
Check a kind of method of cryptical readable image:, read this hidden image with the infrared radiation chromatography zone in 1000 to 2500 nanometer wavelength range.
Cryptical readable image mark substance of the present invention adopts inorganic infrared absorbing material, and its advantage is to greatly reduce the production cost that cryptical readable image is made, and it has obvious absorption equally with 800 nanometers in the visible light district in addition.The present invention uses of the same race behind the printing ink or the xenogenesis mode of printing is printed on the different aspects/plane of stock by infrared absorbing material and infrared permeation material are made, and reaches three-dimensional and covers, and finally reaches the purpose that hides Info.
The specific embodiment
How further specify the present invention below in conjunction with accompanying drawing realizes:
Embodiment
1. described infrared absorbing material is contained in the printing-ink, and its weight percentage in printing ink is 0.1%-30%; Described infrared absorbing material is a graininess, and its particle diameter is the 500-600 nanometer, is made into printing ink, i.e. INFRARED ABSORPTION printing ink;
2. described infrared non-absorbing material is contained in the printing-ink, and its weight percentage in printing ink is for O.1%-30%; Described infrared non-absorbing material is a graininess, and its particle diameter is the 500-600 nanometer, is made into printing ink, promptly infrared non-absorption printing ink;
3. the numeral that earlier infrared absorbing material is configured in advance with offset printing, figure or coding are as shading;
4. use then offset printing, silk screen or carved gravure technology on this shading once more chromatography print infrared non-absorbing material;
5. the ink colors that the ink colors that described 4 step application offset printings, silk screen or carved gravure technology print use uses than 3 step offset printings is slightly dark or approximate with its color, and described 4 step printing areas cover numeral, figure or the coding of 3 steps printing;
6. after the large tracts of land of offset printing or silk screen covered, original small size, more shallow first impression shading were capped, so naked eyes are invisible, as seen configured in advance under the INFRARED ABSORPTION light source is observed and hid numeral, figure or coding;
7. after the immense pressure or the covering of large-area figure line of carved gravure, original small size, more shallow first impression shading are capped, so naked eyes are invisible, the hiding numeral, figure or the coding that as seen configure in advance under the INFRARED ABSORPTION light source is observed;
8. the hiding numeral, figure or the coding that configure in advance through covering, under the INFRARED ABSORPTION light source is observed as seen.
