Embodiment

[0038] Using the method of the present invention to figure 1 The "Z" shaped miniature information shown is enlarged and hidden.

[0039] Amplified Information Model

[0040]

[0041] Take x=12 in the present embodiment, a=4, T b =9mm, Tr=13mm, λ=8.5mm, then the length of the basic layer vector graphics is set to 71mm, then a whole row of vector graphics, that is, the total length of the three vector graphics and the intervals between them is 215mm, for To achieve the purpose of revealing that the grating can completely cover the basic layer, set the length of the revealing grating to 230mm, so that the period of the "Z" vector graphics is 9mm, the width is 8.5mm, and the length is 71mm. The period of the grating is 13mm, and the length is 230mm, the width is 10mm, and the frequency y=8.

[0042] Step 1, make hidden information vector graphics: In CorelDraw, create a new file canvas A, use the smart drawing tool to draw a "Z" vector graphics, in "Window - Docker - Transfo...

Abstract

The invention discloses a method for enlarging micro information for the anti-counterfeiting of a printed product. An information enlargement model is adopted which is shown in the description. In drawing software, a vector graph is drawn, the period, width and length of the vector graph are set according to the information enlargement model, and the single vector graph is duplicated for multiple times to complete the production of a hidden information vector graph; next, the period, width and length of a grating are set according to the information enlargement model, and then a single rectangle is duplicated for multiple times to complete the grating production; and finally, the grating is covered over the hidden information vector graph, and the enlargement of the micro information is completed upon the arrival at the position of a complete overlap.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting of printed matter, and in particular relates to a micro-information amplification method for anti-counterfeiting of printed matter. Background technique [0002] With the continuous progress of society and the continuous progress of science and technology, anti-counterfeiting technology is a technology that people have been studying, and it has become a brand-new technology that is constantly developing and changing. At present, anti-counterfeiting printing technology is the most commonly used anti-counterfeiting means with the simplest identification and the lowest cost in our country. However, the current anti-counterfeiting methods are all based on the display of hidden information, that is, to hide the information to be hidden in the carrier image, make a matching grating sheet, and use the grating sheet to reveal the hidden information. This method is cumbersome, has many steps, ...
