Abstract
The invention discloses a kind of method that offset printing process makes latent image pattern, adopt offset printing four-color process, described four looks are with the first look of full version site form printing, print with average line strips, blank parts forms second look of pattern A, with the 3rd look of site form printed patterns B, with the printing of average line strips, blank parts forms the 4th look of pattern B.What the present invention was designed with figure line by ink coordinates, and adopts traditional offset plate making technique can realize latent image pattern, with low cost, is convenient to apply at low denomination nominal value and common security, certificate.
Description
Technical field:
The present invention relates to anti-counterfeiting technology, particularly a kind of method adopting offset printing technique to make latent image pattern or hidden pattern.
Background technology:
Latent image is widely used in all kinds of money and marketable securities as an anti-counterfeiting technology.Latent image without the need to by particular instrument, be easy to popular and identify that there is desirable antifalse effect.At present, the preparation method of latent image mainly contain following several in:
1, carved gravure technique is adopted.Form raised line clearly on printed article surface, concave-convex sense is strong, and in the gravure figure line of complexity, be also concealed with hidden pattern or word, utilize the high low-resistance photosensitiveness of raised line, frontlighting can see hidden pattern clearly.Because carved gravure is the distinctive technique of print paper money industry, plate cost is high, and ink consumption is large, produces large amount of sewage, need drop into expensive environmental protection treatment expense.
2, special plate-making is adopted.By latent image pattern and non-latent image pattern with identical density, equidirectional but after the different line design of angle overlap scan, make a plate after the process of image modification software by electronic technology synthetic method, strengthening site, produces sharpened effect, and this edition suggestion is set to the first look yellow version.Its excess-three look is respectively by identical density, equidirectional but the different line design of angle.Observe under different light rays angle, latent image pattern can be seen.These class methods mainly rely on plate-making design technology, and its lithography process is complicated, there are certain requirements non-latent image pattern global design tool.
Summary of the invention
Carved gravure technique for current main flow realizes latent image pattern, its cost is high, be unfavorable for applying and need special mask-making technology to realize latent image pattern, the shortcoming of its lithography process complexity, the object of the present invention is to provide a kind of easy, general offset printing process to make the method for latent image pattern.
Goal of the invention of the present invention is achieved through the following technical solutions:
Offset printing process makes a method for latent image pattern, and adopt offset printing four-color process, the first look prints with full version site form; Second look is with the printing of average line strips, and blank parts forms pattern A; 3rd look prints with site form; 4th look is with the printing of average line strips, and blank parts forms pattern B.
Described first look and the 4th look adopt the printing of metal-to-metal adhesive printing ink, and described second look and the 3rd look adopt common offset ink printing.
Colour-difference in printing of described offset ink and metal ink is apart from be DL≤30 and-12≤DC≤13 and DH≤7, and color data adopts DATACOLOUR SF600 to test, and software is Color QCv1.3.Test condition is D65 light source, comprises bright luster, comprises UV, and 6.6mm tests aperture.This data area can be variant with the difference of tester or test condition.
Dot density >=50% of described first look; 3rd look dot density is in 10%-50% scope.
Width, the interval of the lines of described second look and the 4th look consistent.Line thickness and interval width ratio are in 1/2-3 scopes.
Simultaneously described second look and the 3rd look print in same version, merges into of the same colour, and version line is overlapping.
The latent image pattern obtained by the inventive method, changes visual angle and can observe different patterns, reach false proof object with this.
What this invention was designed with figure line by ink coordinates, and adopts print paper money tradition offset plate making technique can realize latent image pattern.With low cost, be convenient to apply at low denomination nominal value and common security, certificate.

Detailed description of the invention
Embodiment 1
Golden metallic offset ink:
First look: adopt golden metallic offset ink, with the full version printing of 75% dot density.
Second look: average print lines, blank parts forms flying bird pattern A.Adopting common offset ink printing, is DL=23.27, DC=-6.24, DH=4.28 with the color distortion of golden metallic offset ink in printing of the first look.
3rd look: 20% dot density printed patterns B, ink is with the second look.
4th look: average print lines, blank parts forms pattern B i.e. " print " word mark.Ink is with the first look.
Change visual angle and can observe different patterns to reach false proof object.Observe in the vertical direction, the bird circled in the air can be seen, observe in 45 ° of directions, " print " word mark can be seen.Effect is as Fig. 1,2.
Embodiment 2
Red metal-to-metal adhesive printing ink:
First look: adopt red metal-to-metal adhesive printing ink, with the full version printing of 70% dot density.
Second look: average print lines, blank parts forms bouquet pattern C.Common offset ink printing is DL=8.23, DC=4.84, DH=2.03 with the color distortion of red metal-to-metal adhesive printing ink in printing of the first look.
3rd look: 15% dot density printing Sunny D, ink is with the second look.
4th look: average print lines, blank parts forms Sunny pattern D.Ink is with the first look.
Change visual angle and can observe different patterns to reach false proof object.Observe in the vertical direction, bouquet pattern can be seen, observe in 45 ° of directions, Sunny pattern can be seen.Effect is as Fig. 3,4.
