Specific embodiment
In order to illustrate the embodiments of the present invention more clearly, Detailed description of the invention a specific embodiment of the invention will be compareed below.
It should be evident that drawings in the following description are only some embodiments of the invention, those of ordinary skill in the art are come
It says, without creative efforts, is also possible to obtain other drawings based on these drawings, and obtain other real
Apply mode.
Embodiment one:
The production method of the mark of the present embodiment, is applied on substrate, for the convenience of description, the substrate of the present embodiment is selected
Printed matter, printed matter can be the materials such as paper wood, film, metal, and the present embodiment selects operplate printing product as substrate, substrate 1
There is no printed patterns for blank substrates.
Specifically, the production method of the mark of the present embodiment, comprising the following steps:
Judge whether substrate reflects infrared ray；
Since the substrate 1 of film printing product cannot reflect infrared ray, one layer of reflection infrared ray is first first applied on the surface of substrate 1
Material, after solidification formed infrared reflecting layer 2, then infrared reflecting layer 2 surface coating or printing infrared transmitting material, Gu
Infrared not absorbed layer 3 are formed after change, specific infrared reflective material can select colourless infrared reflection oil at present on the market
Ink, paint；Infrared transmission material can be selected at present on the market with coloured infrared ray transmitting ink, paint, according to printing
Pattern requirement selects color coating, for example selects red and green infrared transmission ink and colourless infrared transmission ink coating
A colored pattern out, coating processes can be by the way of even applications, can also be by the way of roller coating；Cured mode
Colored infrared ray transmitting ink shape can be seen after solidification under visible light using modes such as hot setting, UV solidifications
At printed patterns.
In order to protect infrared not absorbed layer 3, transparent material layer, such as non-colored light are coated on infrared 3 surface of not absorbed layer
Oil forms transparent protective layer 4, when substrate punch forming or surface can be made to carry out the techniques such as high temperature sterilization or chemical reagent processing
Infrared not absorbed layer is protected not to be destroyed.
On 1 surface of substrate, outermost transparent protective layer 4 carves dent, forms mark.In the infrared light supply of specific band
Under irradiation, using reflective imaging method, mark such as infrared camera under infrared photosensitive image-forming component does not have at dent
Clear zone is formed by infrared reflecting layer reflection infrared ray, since material for carving on it becomes at dent, scattering occurs for light or absorbs to be formed secretly
Area, this just constitutes the mark for being easy to distinguish, and engraving mode can select Laser Jet.
As shown in Figure 1-3, infrared not absorbed layer 3 shows exquisite multicolour pattern under visible light, after Laser Jet, due to
The interference of pattern, mark are not easy to be read.Under infrared thread environment, with infrared light supply irradiation using infrared camera as image
Collector, by reflective imaging mode, infrared light is anti-to infrared reflecting layer 2 by transparent protective layer 4, infrared not absorbed layer 3
Clear zone is formed after penetrating infrared ray, by Laser Jet partially due to the scattering or absorption of infrared ray form dark space, so mark is just
It highlights, is easy to distinguish.
The information that mark can be distinguished for text, number, one-dimensional bar code, two dimensional code, pattern etc..Specifically, this reality
That applies example is identified as two dimensional code
The production method of the mark of the present embodiment, production process is simple, and the recognition rate of the mark of production is high.
The present embodiment also provides a kind of mark, is made by the production method of the mark of the present embodiment.The mark will not influence
The visual effect of picture and text background on substrate, meanwhile, the picture and text background on substrate will not influence the recognition of mark.
The present embodiment also provides a kind of reading method of mark, comprising the following steps:

The surface of material 1；Wherein, the wave-length coverage of the infrared light of infrared light supply transmitting is 800~1200nm；
By the way that the mark at infrared 3 dent of not absorbed layer is imaged in the sensitive image acquisition device of infrared light supply
Recognition；Specifically using infrared camera as image acquisition device, by reflective imaging mode, infrared light passes through transparent protective layer
4, infrared not absorbed layer 3 forms clear zone after reflecting infrared ray to infrared reflecting layer 2, forms dark space, institute by the part of Laser Jet
It is just highlighted with mark, infrared camera imaging recognition.
The reading method of the mark of the present embodiment, is irradiated by infrared light supply, is clear zone without pitted region, pitted
