Embodiment 1

[0074] The three major technological processes for making the method of printing iron anti-counterfeiting marks are as described above, and the specific process steps for making the invisible graphic relief printed on the colored anti-counterfeiting marks are:

[0075] (1) First make a flexible glazing plate

[0076] 1> make film (film) according to customer data file; In the present embodiment, customer's data file is " Baosteel printing iron ", and the film specification that makes is 1090 * 900mm format;

[0077] 2> drying out the flexographic plate with concave-convex three-dimensional relief on the flexible plate with the film made above; this flexographic plate is a polyester plate base resistant to ultraviolet varnish, and the thickness of the plate is 1.14 mm. Usually, there are three types of embossing on the flexo plate, one is to use the graphic part to protrude and the blank part to be concave; or to use the graphic part to be concave and the blank part to be protr...

Embodiment 2

[0093] All manufacturing processes are the same as in Example 1. Only in the conditions of the specific process steps of printing invisible graphic relief and printing color anti-counterfeiting marks, the proportion of ultraviolet fluorescent ink used by the sixth unit is different. The process step of concrete printing invisible graphic and text relief is identical with embodiment 1, and just condition and specific content are different, as:

[0094] Printing process steps of "invisible graphic relief":

[0095] (1) Making a flexible glazing plate

[0096] 1> make film (film) according to customer data file, in the present embodiment, customer data file is " ancient well ", what make is the film of 1090 * 50mm format specification;

[0097] 2>Use the film to print out the flexographic plate with concave-convex three-dimensional relief for the machine. This plate is a polyester plate base with UV-resistant varnish, and the plate thickness is 1.14 mm;

[0098] In this embodi...

Abstract

Present invention refers to tin plate printing invisible forgery prevention label and making method. Forgery prevention label contains metal base plate and real line constituent medallion pattern with spacing thickness, elasticity and different colour interpenetration printed on metal base plate. Said pattern has micro letter, lightness loop image, writing with UV fluorescence UV fluorescence printing ink, memorization and invisible chart writing relief. Making method includes forgery prevention label design, plate making and printing three processes. Metal printing used UV fluorescence printing ink is made from UV fluorescence whitening agent and ultraviolet light printing ink. Said invisible chart writing relief can be seen on bright light by side-looking forgery prevention label chart writing surface, bank note watermark, with sagging sense touched by hand.

Description

technical field [0001] The invention relates to an anti-counterfeiting mark and a manufacturing method, in particular to an invisible anti-counterfeiting mark printed on iron and a manufacturing method. Background technique [0002] Printing anti-counterfeiting marks on metal has its particularity. First of all, for metal printing, the substrate for printing is metal. Such as tinplate, chrome-plated steel sheet, etc., rather than paper, plastic and other non-metallic materials. The development of iron printing technology is later than that of paper printing technology. It can be said that it is not yet mature in some respects. The final product of iron printing is usually a metal packaging container. Therefore, metal printing is the pre-process of forming metal packaging containers. Therefore, it must meet some basic characteristics of metal packaging manufacturing and use, such as the need to have mechanical processing properties (such as stretching, compression, stampi...
