Description
Technical field
The present invention relates to a kind of method for anti-counterfeit, relate in particular to a kind of method of in the block of information of CD, making anti-counterfei waterprint.
Background technology
At present, CD is as the most widely used distribution media, because its convenience and cheap cost, at music CD, VCD, DVD, BD video disc all play very enormous function, according to incompletely statistics in the interchange of CD-ROM, DVD-ROM program rom and various digital informations, the optical disc production in China every year, sales volume this shows that all at tens the use of CD is very universal.Because the cost of CD itself is very low, but often the content of its carrying is very expensive, the economic interests that contain are very huge, so often the lawless person also utilizes CD to carry out piracy as media.Because the optical disc product outward appearance is single, pirate molecule is easy to copy, and the Mould Code of present domestic implementation identifies that product place of production system ratio is easier to be imitated by the people, and ordinary consumer can't be distinguished the CD of pirate molecule making and the difference of copyrighted product at all, and pirate molecule is had an opportunity to take advantage of.So, be badly in need of a kind of technology that makes ordinary consumer distinguish true and false product easily on the CD market at present.
At this situation, we have invented the method for making anti-counterfeiting mark in the optical disc information district (patent of invention number: 200610078411.8) in 2006, this method, in the block of information of prerecorded optical disc, make macroscopic anti-counterfei waterprint, play the effect that can allow consumers in general distinguish authentic discs and pirated CDs easily.This anti-counterfei waterprint is positioned at the block of information, can't copy to duplicate, and does not influence the information reserves of CD, does not influence the quality of CD, and anti-counterfei waterprint can be made according to the shape of customer requirement.
Summary of the invention
It is simpler that the technical problem to be solved in the present invention provides a kind of technology, the method for making the anti-counterfei waterprint that can't duplicate in the block of information of CD that cost of manufacture is lower.
A kind of method of making the anti-counterfei waterprint that can't duplicate in the block of information of CD provided by the invention comprises the steps:
Step 1 forms one deck patterned layer in the block of information of stamper to be processed, and this patterned layer has shaded portions and blank parts;
Step 2 is carried out nickel plating to form figuratum zone on stamper, plates the thick metallic nickel of 10～30 μ m with the zone that is exposed to described blank parts at stamper;
Step 3 washes the shaded portions of patterned layer, thereby forms the stamper with predetermined anti-counterfei waterprint.
Preferably, described patterned layer is printed by the ink-jet flat-panel printer.
Preferably, described metallic nickel carries out evaporation by evaporator or the sputter machine carries out sputter.
Preferably, adopt organic solution with described typographic patterned layer flush away, described organic solvent is acetone or ether.
Preferably, described stamper to be processed is the stamper of handling without transpassivation.
The another kind that the present invention also provides is made the method for the anti-counterfei waterprint that can't duplicate in the block of information of CD, comprise the steps:
Step 1 forms one deck patterned layer in the block of information of stamper to be processed, and this patterned layer has shaded portions and blank parts;
Step 2 makes the metallic nickel oxidation stain on the stamper that is exposed to blank parts with acid solution;
Step 3 washes the shaded portions of patterned layer, thereby forms the stamper with predetermined anti-counterfei waterprint.
Preferably, described patterned layer is printed by the ink-jet flat-panel printer.
Preferably, described acid solution is for containing nitric acid 3～16%, ethylene glycol 5～30%, and surplus is the solution of water, and described number percent is percent by volume.
Preferably, adopt organic solution with described typographic patterned layer flush away, described organic solvent is acetone or ether.
Preferably, described stamper to be processed is the stamper of handling without transpassivation.
The present invention is by adopting plating nickel behind the printed patterns, or make the stamper variable color of the white space of pattern, flush away printed patterns again, thereby form the nickel dam that has suitable height and do not influence the optical disc information record in the block of information, or the oxidation pattern of formation and other regional different colours, formed the anti-counterfei waterprint that can be convenient to user's identification at last.Because the present invention has broken away from complicated coding and to the dependence of stamper litho machine, the technology of making watermark is simple, cost is low, qualification rate also than before method improve greatly, be fit to very much large-scale promotion application.
Embodiment
In the block of information of CD, make watermark, can't influence canned data in the CD, have suitable difficulty.We know, the watermark in the CD is that the difference by light reflects to form, as long as it is different to have light and other light that do not have watermark region to reflect that the regional reflex of watermark returns, just can observe with the naked eye the existence of watermark.
In addition, the information in the CD is that the pitting with the different length of zigzag shape shows, and is example with the DVD CD, the hole type groove of DVD CD is spaced apart 0.74 μ m, the about 0.35 μ m of DVD hole molded breadth degree, degree of depth 160-300 μ m, the about 0.400 μ m of the shortest hole type.Because the gradient on the hole molded breadth degree on every CD and the degree of depth and edge, hole is consistent substantially, so usual CD our reflected light seen is just the same, whole block of information just presents same color.If it is different to control the gradient and other regional pits types on the width, the degree of depth of the pits type of specific region or edge, hole, the reflected light of these specific regions just and other regional reflected light with different, human naked eyes seem just to have formed watermark, certainly, this difference must not influence reading of information, the variation that is to say this hole type is can not ether big, can not surpass the scope that compact disk standards allows.
Therefore, the method for the present invention's employing is specific as follows:
(CD, DVD all can normally to make the CD master-disc that needs the making anti-counterfei waterprint, stamper is made of metallic nickel), but what ASY (symmetry) parameter request was made is low for (CD can be produced on-13～-6 scopes well, DVD can be produced on-3～+ 6 scopes), after stamper is made, can normal wash also beat the rushed back hole, but cannot Passivation Treatment.The security pattern that will make is printed on the ink-jet flat-panel printer in the block of information of CD master-disc then, forms predetermined patterned layer.Patterned layer comprises the blank parts that comes out in shaded portions that covers in the stamper subregion and the other subregion that makes stamper.For example, print the literal of " false proof " two words, the font part promptly is to hide part, and the part beyond the font promptly is a blank parts.
The stamper of having printed pictograph can adopt following two kinds of methods to handle separately respectively: one, use evaporator or the sputter machine metallic nickel to stamper information faces evaporation or sputter 10～30 μ m thickness; Two, use chemical acid solution to make the nickel oxidation stain, for example, can use nitric acid (40% concentration) 20ml, ethylene glycol 20ml, pure water 60ml soaks stamper 20s.
Stamper after the processing is used the acetone soaking and washing again, washes fully until the figure with printing of inkjet printer, and so far, a CD master-disc and a making that has anti-counterfei waterprint finishes.The CD that duplicates in enormous quantities with this stamper has also just had anti-counterfei waterprint.Certainly, the organic solvent that also can adopt other cleans the pattern of ink-jet, for example, and ether.So long as can wash ink logo off, and it is just passable not destroy stamper.
No matter the present invention is the watermark which kind of method is made, can with the naked eye see at an easy rate, with the method for evaporation or sputter nickel is to have changed the printer prints figure the hole of shield portions is not dark, cause catoptrical difference, and the method for chemistry has changed the color on stamper surface, two kinds of methods all do not reach the stage that influences the CD parameter to the influence of physics hole type, so can not influence reading of optical disc information, do not influence the memory capacity of CD yet, because anti-counterfei waterprint and coding are irrelevant, the bootlegger also can't duplicate out with watermark, thereby reaches false proof purpose.
The method for making of CD anti-counterfei waterprint of the present invention has been broken away from complicated coding and to the dependence of stamper litho machine, the technology of making watermark is simple, and cost is low, qualification rate also than before method improve greatly, can carry out large-scale promotion and application.
