The leaflet of (including either statically or dynamically content) uses common four color inks (including tradition ink, carbon dust and ink) at printer
Carry out on (including conventional presses, digital printer and normal printer) printing and (include traditional printing, digital printing and beating
Print), the watermark effect duration using this technology print is longer than the watermark effect duration printed with fluoresent printing ink, and cost of manufacture is low,
Hide watermark content as can be derived again more application for dynamically changeable.This technology is independent of printing process, the kind of printer
Class, the kind of printing-ink, film setter and the raster processor of direct plate maker and the raster processor of digital printer.
Background technology
Instantly in business activity, how to allow product pack, label, the leaflet such as certificate and business document has antiforge function
Always one of most concerned technology of author.Utilize ultraviolet light to irradiate and identify that the watermark being hidden in leaflet is numerous false proof
One in technology, its using method is: the watermark hidden in leaflet is the most invisible, under ultraviolet light irradiates,
Fluorescence can be sent.Although the application of this technology is long-standing, but this method has several limitation: the first, it must use ultraviolet glimmering
The watermark that ink printing is hidden, because adding visible fluorescence compound in fluoresent printing ink；The second, fluoresent printing ink
Can lose efficacy within certain time limit in the sunlight, at most 1-2, will lose efficacy after few several weeks；3rd, fluoresent printing ink cost
Relatively common four color inks are expensive a lot, add production and application cost；4th, conventional presses employing fluoresent printing ink is all
The watermark of printing immobilized substance, if to accomplish that the content of the watermark hidden is dynamically changeable, is necessary for number to be used
Press printing, and the digital printer kind with fluoresent printing ink support is considerably less, even if supporting, its ultraviolet supported
Fluorescent ink expiration date is shorter, does not have universal practical value.
In sum, for overcoming drawbacks described above, it is necessary to leaflet to be hidden the making side of the discernible watermark of ultraviolet light
Method improves.
Summary of the invention
The technical problem to be solved is not use fluoresent printing ink printing, but uses common four color inks
(including tradition ink, carbon dust and ink) is enterprising at printer (including conventional presses, digital printer and normal printer)
Row printing (including traditional printing, digital printing and printing), reaches the anti-counterfeiting characteristic that fluoresent printing ink printing watermark is similar.
The technical solution used in the present invention is with the similar white base such as ordinary white paper, common chalk and white plastic film
The material at the end, as fluorescence source, adds printing net-point structure and the color combination of our unique design, uses converse thought to reach
Above-mentioned anti-counterfeiting characteristic.Not only effective by the method, and avoid all limitations using fluoresent printing ink to produce, in conjunction with
Digital printing, will be derived by more application.
Ordinary white paper in order to increase its whiteness, can add fluorescein, i.e. fluorescent whitening agent in the fabrication process.So
Ordinary white paper there will be fluorescence under ultraviolet light irradiates.Our technical scheme is exactly that hiding watermarking section is left white,
And background ink is covered, when causing ultraviolet light to irradiate, naked eyes viewing has aberration phenomenon to produce, thus reads out hiding watermark
Content.The material of the similar white substrate such as common chalk and white plastic film also can add fluorescent whitening agent, thus possess with
The application scheme that ordinary white paper is same.
Watermarking section must be left white if the simplest, it is existing that can cause viewing in the sunlight just can produce obvious aberration
As, so we use special net-pont design and color combination, cause watermark in the sunlight and background with the naked eye to watch colourless
The effect of difference.
Because the net-pont design used in our technical scheme and color combination all complete before print, do not rely on photograph
Row's machine, direct plate maker, the raster processor of digital printer.In other words, effect files all completes before print, and rear end can
Make a plate on any platemaking equipment to take, then carry out traditional printing, or directly carry out digital printing.
The present invention contrasts prior art a following beneficial effect:
One, the technical scheme that the present invention provides uses common four color inks (including tradition ink, carbon dust and ink) to reach
The anti-counterfeiting characteristic that fluoresent printing ink is similar.
Two, the hiding watermark anti-counterfeiting feature timeliness of this scheme printing is long.Hide the false proof effect duration of watermark and common four colors
Ink (including tradition ink, carbon dust and ink) is relevant, because the most common four color inks (include tradition ink, carbon dust and ink
Water) there is considerably long effect duration, so this anti-counterfeiting characteristic also will continue the long duration.
Three, occur without extra Ultraluminescence printing-ink cost of manufacture.Common four color ink itself (includes traditional oils
Ink, carbon dust and ink) with low cost, if leaflet own to print with regard to chromatic colour content, then and this hiding watermark can one
Play printing, do not increase any extra cost and operation.
Four, applicable surface is extensive.This technology is independent of printing process, the kind of printer, the kind of printing-ink, film setter
Raster processor and the raster processor of digital printer with direct plate maker.Thus allow the applicable surface of this technology almost cover
The printing covering all employing four color inks (including tradition ink, carbon dust and ink) makes.As long as employing has the most glimmering
The material of the similar white substrate such as the ordinary white paper of light intensity, common chalk and white plastic film, all can obtain effectively effect
Really.
Five, due to this technology kind independent of printing-ink and the raster processor of digital printer, so this technology
Broad category of digital printer can be supported, once support digital printer, then achieve that hiding watermark content dynamically may be used
Become, thus will be derived by more application.Disclosure dynamically changeable not only supports that text is variable, it is possible to support that pattern is variable.
