Description
Technical field
The present invention relates to field of anti-counterfeit technology, and in particular to a kind of embossing production dark line, latent image and unwinds lock and integrally combines
Method for anti-counterfeit.
Background technique
Existing market is more and more extensive to the anti-fake demand of various products, especially cigarette contract for fixed output quotas product anti-counterfeiting technology be even more want
Ask higher and higher.Security pattern mainly has three ways, such as dark line, latent image, unwinds lock, and the prior art mostly uses greatly intaglio printing work
Skill make security pattern, but this intaglio printing anti-counterfeiting technology the problem is that: (1) due to printing ink have diffusivity,
To engraving precision there are large effect, such product cannot accomplish very fine, the most fine degree that printed matter can be accomplished at present
Usually 100 lines/centimetre；(2) printed patterns are 2D planes, do not have 3D three-dimensional sense, (i.e. the 3D shape of site is logical for production latent image
Text or pattern are hidden in shading by the reflection for crossing different angle light with reaching, and only can just be seen by some angle hidden
The pattern of hiding) antifalse effect it is poor；(3) intaglio printing production unwinds lock security pattern (i.e. using site or cable as base
Our unit forms and shows various printed patterns) cannot preferably hide because the mode that unwinds lock will need it is hiding
Text or pattern position are slightly deviated, and the amount that the difficult point printed is deviated at this, if the amount of offset does small, print
Ink diffusion after brush, so that also can't see hiding pattern with solution locking plate after printing product, or hiding pattern does not see Chu,
To which antifalse effect cannot be played；If the amount of offset is done greatly, do not need visually be seen in hiding with locking plate is solved
Hold, is then not achieved to unwind and locks anti-fake purpose.
Summary of the invention
It is an object of the invention to aiming at the shortcomings in the prior art, and provide that a kind of three-dimensional sense is strong, fineness is high, anti-fake
The good embossing of effect makes dark line, latent image and unwinds the method for anti-counterfeit that lock integrally combines.
A kind of embossing production dark line, latent image are provided and unwind the method for anti-counterfeit that integrally combines of lock, comprising the following steps:
Step 1: first producing evenly arranged grid using image processing software, all sites in the grid are formed
Shape be hemispherical；
Step 2: hiding pattern will be needed, the offset of certain distance is made in corresponding hemispherical site within a grid,
Offset is 0.02-0.04mm, is directly carved machine using laser after carrying out offset and is carved on copper roller, to obtain and unlocking film
The implicit pattern shown after piece cooperation；
Step 3: choosing the part-spherical site in grid using image processing software and designing required cutting
Angle, then half-and-half the surface of spherical site is cut from the angle of different cuttings respectively, so that light passes through by cutting net
Different latent image patterns is showed by different reflection angles after point 4, and machine is directly then carved using laser and is carved on copper roller
It carves；
Step 4: using image processing software, the part-spherical site in grid is chosen and by its entire reduced profile,
Hemispheric diminution site is formed, these hemispheric diminution sites form the identifiable dark line pattern of naked eyes, then using sharp
Light is directly carved machine and is carved on copper roller；
Step 5: carrying out electrobrightening to the pattern residue carved on copper roller, keep the surface of its all site smooth, nothing
Burr；
Step 6: carrying out chromium plating on copper roller after electrobrightening, reaches and increase hardness and corrosion resistant performance；
Step 7: the copper roller handled well is assembled on embossing machine, stock is embossed to get dark line, latent image is arrived
And unwind the security pattern that lock integrally combines.
In above-mentioned technical proposal, in step 2, machine engraving, spot size 0.005mm, carving depth are directly carved using laser
For 0.06mm, engraving resolution ratio is 5080dpi.
In above-mentioned technical proposal, in step 2, the offset is that site deviates to the left or to the right, and offset is
0.03mm。
In above-mentioned technical proposal, in step 3, the angle of the cutting is ± 45 degree and/or ± 135 degree.
The solution have the advantages that:
Compared with prior art, the invention has the following advantages that
(1) engraving site of the invention is that hemispherical is compared with printing net-point, the anti-fake figure of three dimensional hemispherical site production
The three-dimensional sense of case is stronger, and when especially making latent image pattern, the 3D shape of site is formed by the reflection of different angle light
The latent image pattern of 3 D stereo, antifalse effect are more preferable；
(2) present invention can accomplish finer that engraving cable fineness can reach 200 using the site that laser directly carves machine engraving
Line/centimetre, and the fineness of printed matter can only achieve 100 lines/centimetre；
(3) present invention directly carves machine using laser and carves obtained copperplate, and embossing technique is recycled to imprint on the substrate,
The rate of transform is up to 95% or more, can be good above stock required for being transferred to the pattern of engraving, and entirely make
It is more environmentally-friendly without using printing ink during making；
(4) security pattern that makes of the present invention by dark line, latent image and unwinds three kinds of anti-counterfeiting technologies of lock and is combined into one, thus
Realize preferably antifalse effect.
