Problems solved by technology

[0002] In the existing banknote printing process, gravure printing is mostly used when printing the main pattern. The pattern printed by this printing technology is composed of dots and lines, and is higher or lower than the paper surface, with a three-dimensional effect. It is very easy to identify (Southwest Finance, Issue 4, 2004), and the numbers are printed with double numbers horizontally and vertically. The horizontal numbers are black and the vertical numbers are blue, and the horizontal and vertical numbers are the same. Although technology has a certain anti-counterfeiting effect, with the continuous advancement of science and technology, the ability of criminals to counterfeit banknotes and other securities is also strengthening. How to further change the printing method, increase the content of printing, and increase the difficulty of printing has become a problem for scientific researchers. one of the directions

Abstract

The multifunctional number printing machine for safety printing includes one number relief printing unit, which includes at least one number cylinder with several colors in the same plate. The one-plate-several-color number cylinder is used in the one-plate-several-color printing of at least one of the transverse number and the vertical number in bank note or securities. Introducing the said multifunctional number printing with one-plate-several-color number cylinder can enrich the printing content in the number and other anti-fake pattern in bank note and securities, raise printing difficulty and raise the anti-fake level.
