[0003] In 2006, Xibai Holdings Co., Ltd. disclosed the patent number (200480018382.5) of "Method and Device for Inducing Patterns in Coatings Containing Magnetic Particles by Magnetic Field Action". method, to a certain extent, has played a positive anti-counterfeiting role; but the defect of this method is that each area of ​​the pattern is controlled by the magnetic field generated by the same magnetic circuit board, and is cured at one time, while the magnetic fragment pigment at the critical point of each area is subject to multiple Influenced by the ma

Example Embodiment

[0045] like figure 1 and figure 2 As shown, the anti-counterfeiting pattern is divided into mutually symmetrical areas 101 and 102; the brightness and color of the areas 101 and 102 are symmetrically changed when viewed from different angles; in the cross-sectional view, the section 103 corresponds to the area 101, and the section 104 corresponds to the area 102; It can be clearly seen that the arrangement angles of the pigment fragments in area 101 and area 102 are very different, so that the brightness and color of the two areas appear symmetrically when viewed from different angles.

[0046] figure 1 The preparation method of the anti-counterfeiting pattern that produces symmetrical changes with the viewing angle comprises the following steps:

[0047] Step 11: Apply magnetic optical variable ink on the base material; the printing method can be selected from gravure printing, letterpress printing, offset printing, silk screen printing and coating, and the thickness of th...

Abstract

The invention relates to a method and a device for preparing an anti-counterfeiting pattern capable of symmetrically changing in brightness or colors with visual angles. The preparation device comprises a first magnetic field generation device, a second magnetic field generation device, a first curing light source, a second curing light source, a blocking grid plate and a base material conveying device. The anti-counterfeiting pattern prepared by the preparation method can change symmetrically by the methods of magnetic field induction, semi-blocking curing, secondary magnetic field induction and secondary curing, boundaries of all regions are clear and obvious, and fine stripes and the pattern can be realized; the preparation process can be kept continuous without interruption; and one magnetic field and one blocking curing are used as one unit, a plurality of units can generate a plurality of regions with the changes in the brightness or the colors, the preparation process is more complex, and the anti-counterfeiting function is higher.

Description

technical field [0001] The invention relates to a method and device for preparing an anti-counterfeiting pattern product, in particular, the invention relates to a method and a device for preparing an anti-counterfeiting pattern that produces symmetrical changes in light and shade or color as the viewing angle changes. Background technique [0002] All kinds of anti-counterfeiting products play an important role in every corner of the world; scientific research institutes and enterprises at home and abroad all require modern anti-counterfeiting technology to be "easy to identify and difficult to forge". Products with low manufacturing process are easy to be imitated. As time goes by, a large number of anti-counterfeiting technologies such as fluorescent anti-counterfeiting, temperature-changing anti-counterfeiting, and holographic patterns with relatively simple structures gradually lose their anti-counterfeiting effects and begin to withdraw from the anti-counterfeiting mark...
