Abstract
The invention relates to a method for printing a colored anti-counterfeiting image by colorless fluorescent ink. The method comprises the following steps of: 1, separating colors of the anti-counterfeiting image to be printed by image processing software according to three colors such as red, green and blue; 2, distributing net points according to a photographic negative; 3, making a red, green and blue three-color printing plate; and 4, printing in a printing machine by the red, green and blue colorless fluorescent ink. According to the method, the problem that a printing process of printing the colored anti-counterfeiting image by the colorless fluorescent ink cannot be realized in the conventional colored image printing process is solved. The colored anti-counterfeiting image has the characteristics of bright-colored and colorful images, high concealment, convenience for inspection and high reproducibility.
Description
Technical field
The present invention relates to a kind of anti-counterfeiting printing process that uses colorless fluorescent printing ink.
Background technology
Colorless fluorescent printing ink is also claimed invisible ink usually, is (to send visible light (400～800nm) special ink under the light source irradiation such as 200～400nm) at ultraviolet light.The main component of fluorescent ink is fluorescence face (a dying) material; It is functional luminous pigment, is when ambient light (containing ultraviolet light) shines, to absorb the ability of certain form with the difference of general pigment; Do not change into heat energy; But excitation photon discharges the energy that absorbs with the visible light form, produces the fluorescence phenomenon of different form and aspect.Fluorescent ink forms various colors under the irradiation of ultraviolet light, and after light stopped irradiation, luminescence phenomenon promptly disappeared.Fluorescent particles in the colorless fluorescent printing ink can produce the light of certain limit and clean especially color, like yellow, orange, red, brilliant red, green and green grass or young crops etc.The key that produces this effect is to include extraordinary color pigment in this printing ink, and it can absorb the energy of ultraviolet band, and these power conversion are become long wavelength of visible light.The application of colorless fluorescent printing ink in anti-counterfeit printing is very extensive, have implement simple, cost is low, good concealment, bright in luster, check is convenient, reappearance is strong, variable color is various and can adapt to large-scale production line or characteristics such as packages printing demand.Be generally used for the package anti-counterfeiting printing of banknote, stamp, financial instruments (like check, bond, stock, commercial paper, banker's acceptance bill etc.), name cigarette, famous brand of wine and some high-grade goods etc.If be used in combination, can produce more-good antifalse effect with other anti-counterfeiting technologies.
At present; The printing of colorless fluorescent is to use mode of printings such as lithographic plate, flexible printing forme; Monochromatic light fluorescent inks such as positive forme and Huang, orange, green, red, indigo plant; Print patterns such as simple flower group, lines, icon, LOGO, be utilized under the visible light invisiblely, the characteristic that under ultraviolet light, develops the color reaches the effect of false proof printing.
The printing of conventional color image is to utilize blue or green, pinkish red, yellow, four kinds of color separations of black; Form image through what accumulation of site, use printing machine, four look forme machines, four color inks under the stack of different sites, to be printed as the printing of coloured image with light and shade contrast.
In order to realize that colorless fluorescent printing ink realizes the printing of colored anti-counterfeiting image, the applicant uses traditional printing technology with the forme color separation through repetition test, uses corresponding green grass or young crops, article, Huang, black fluorescent ink but can't form the coloured image consistent with original copy then.Reason is to print through these 4 kinds of primary colors of printing ink; After color separation and using the colorless fluorescent ink printing of same hue; Image that obtains and former figure completely contradict; Because colorless fluorescent printing ink is through luminous behind the UV-irradiation, with printing ink natural daylight carried out the principle that selectivity absorbs back reflection light completely contradict, therefore can't obtain the coloured image consistent with original copy.
Summary of the invention
The object of the invention provides a kind of method of using the colored anti-counterfeiting image of colorless fluorescent ink printing, and it has solved existing coloured image typography can't realize the typography with the colored anti-counterfeiting image of colorless fluorescent ink printing.
Technical solution of the present invention is:
A kind of method of using the colored anti-counterfeiting image of colorless fluorescent ink printing, its special character is: may further comprise the steps:
1] treats the antiforge image with image processing software and carry out color separation processing according to red, green, blue three looks; 2] carrying out network point distribution according to the negative sheet handles;
3] make red, green, blue three look formes;
4] use machine printing on the red, green, blue three look colorless fluorescent printing ink.
Beneficial effect of the present invention:
1, adopts printed matter no image under visible light after the inventive method printing, under ultraviolet light shines, will present coloured image, have that image is bright-coloured, rich color, good concealment, check makes things convenient for, reappearance is strong characteristics.
2, the forme network point distribution in the present invention and the traditional printing is completely contradicted, and only needs to use the negative image to carry out network point distribution and handles, and can be printed as picture, has the advantages that enforcement is simple, cost is low, can adapt to large-scale production line or packages printing demand.
3, light source can be divided into 3 kinds of primitive color lights according to its characteristic, is respectively red, blue and green, and these 3 kinds of light can synthesize the light of all colours through combination.So the present invention does not have specific (special) requirements to fluorescent ink, forme and mode of printing, use very extensive.
The specific embodiment
The present invention uses the method for the colored anti-counterfeiting image of colorless fluorescent ink printing following:
1] treats the antiforge image with image processing software and carry out color separation processing according to red, green, blue three looks;
2] carrying out network point distribution according to the negative sheet handles;
3] make red, green, blue three look formes;
4] use machine printing on the red, green, blue three look colorless fluorescent printing ink.
Print principle of the present invention:
Analyze the coloured image image-forming principle and can know that printing is to use the colorant subtractive process, use blue or green, pinkish red, the yellow mixing to form needed color by different proportion.
Consider that colorless fluorescent printing ink is to use ultraviolet excitation to go out that color comes, the light that it sent is discerned by human eye, therefore can colorless fluorescent printing ink be regarded as light source, uses red, green, blue three looks to form shades of colour according to coloured light additive process principle.
But only rely on the coloured light additive process, still can't realize the colored printing of colorless fluorescent printing ink, also need the forme that printing is used is handled.In the tradition colored printing, the high light of forme does not partly have the site, in the colorless fluorescent ink printing, needs high light partly to be full of the site, therefore, completely contradicts with the forme network point distribution in the traditional printing, needs to use the negative image to be printed as picture.
