Description

The method for anti-counterfeit that a kind of light disturbs

Technical field

The present invention relates to a kind of method for anti-counterfeit; Particularly relate to a kind of method for anti-counterfeit that utilizes light to disturb.

Background technology

The film is separated to be locked on the anti-counterfeiting technology market and has been occurred for many years, film release is that the superfine striped that utilizes meticulous printshop to reach is made picture and text, after being reflected on the printed matter, naked eyes and duplicating are amplified all can't differentiate its content, the principle that utilization is interfered has only the identification diaphragm with coupling to superpose high-visible with translation-angle observation ability with it.Using this technology has monochromatic single angle free hand drawing literary composition false proof, and Fig. 1 a is monochromatic single angle shading schematic diagram; Fig. 1 b is that diaphragm is placed on the schematic diagram on monochromatic single angle picture and text.Shown in Fig. 1 a and Fig. 1 b, shading is an individual layer shading single color printing, directly perusal can't identification icon, after observing, its top can know demonstration " very " word when being placed on identification card, its principle is that top diaphragm is actually the slanted bar line pattern by one group of rule, and following shading also is one group of striped of same width and arrangement, and different is that wherein a part is not corresponding with position on every side, produce wrong row, the part of wrong row forms " very " word.See that separately shading " very " can't distinguish, but can produce the light interference principle when putting diaphragm in the above, can be clearly seen that " very " word; This technology is widely used on the packing and label of commodity, as Chinese toothpaste, SmithKline medicine box, the anti-fake label of drinks etc.Along with the part antiforge function that has for a long time of service time is leaked, lost its antifalse effect, there has been the anti-counterfeiting mark of double-colored pair of angle digraph literary composition in market now, its false proof degree increases thereupon, but because double-colored pair of angle digraph literary composition two dark stacks, false proof part approaches dark purple or black, can influence the overall color effect.In addition, no matter be that the monochromatic single angle free hand drawing literary composition or the making of double-colored pair of angle digraph literary composition all need false proof software cooperation to finish, therefore, its cost of manufacture is higher.

Summary of the invention

Technical problem to be solved by this invention is, overcomes the prior art shortcoming, provides a kind of cost low, and antifalse effect is good, the method for anti-counterfeit that the light of overall appearance disturbs.

The technical solution adopted in the present invention is: the method for anti-counterfeit that a kind of light disturbs may further comprise the steps:

A. make the layering shading;

B. make the layering pattern;

C. the layering pattern superposes;

D. printing.

The shading of described steps A is the monochromatic color lump alternate with white, and greater than 0.04mm, described monochrome is a solid line to the width of described color lump less than 0.1mm.

Described step B makes multilayer pattern by Adobe Illustrator respectively.

Described step C superposes to multilayer pattern by Adobe photoshop, forms the pattern of the many picture and text of monochromatic multi-angle.

The invention has the beneficial effects as follows:, saved production cost because the production of adopting general Adobe Illustrator and Adobe photoshop software can finish anti-counterfeiting mark need not false proof software; In addition, utilize a kind of color to incorporate whole picture and text, its color even can become the part of picture and text, and can realize the variation of three patterns or four patterns, its antifalse effect is better.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

The method for anti-counterfeit that light of the present invention disturbs may further comprise the steps: A. makes the layering shading, and shading is the monochromatic color lump alternate with white, the width of described color lump less than 0.1mm greater than 0.04mm, width is meticulous, and the printing of its rear portion does not reach, and width is crossed thick naked eyes and just can be differentiated and do not reach antifalse effect; Described monochrome can be selected voluntarily according to the needs of product pattern and color, only needs to guarantee that monochrome is a solid line; B. make multilayer pattern by Adobe Illustrator respectively; C. by Adobe photoshop multilayer pattern is superposeed, form the many picture and text of monochromatic multi-angle; D. the pattern after the stack is printed.

Embodiment 1: existing is that example describes to make monochromatic angular three picture and text " genuine piece matter ".

Shown in Fig. 2 a to Fig. 2 d,

A) enter Adobe Illustrator software, make long 2mm, 4 rectangles of wide 0.04mm, color is blue 100,4 rectangle arranged verticals, and the blank of space 0.07mm, forms a rectangle group; Select for use colour table that rectangle group is formed a microgroove colour table;

B) rectangle of a 30mm of establishment is beaten the literal or the letter that need the identification card identification in rectangular window, and as " very " word, font is preferably selected black matrix for use;

C) create profile again, the literal in rectangular window and the window is carried out the filling of microgroove colour table;

D) choose 45 ° of rectangle and " very " word and image rotatings, lines of " very " word and the lines of forming rectangle are staggered fully;

E) optimize picture proof;

F) repeating step b to e makes " product "; Wherein, non-rotating during repeating step d, but upwards skew longitudinally after the choosing " product " is staggered lines of " product " word and the lines of forming rectangle fully;

G) repeating step b to e makes " matter "; The direction of its rotation is opposite with the direction that d is rotated when being repeating step d, and lines of " matter " word and the lines of forming rectangle are staggered fully;
