Analysis of the current misunderstanding of the anti-counterfeiting printing

The status quo: Unprofessional pattern "anti-counterfeiting" can not help but scrutinize, ordinary ordinary pre-production staff scan, you can imitate a very similar pattern, commonly known as "half hour copy phenomenon." This phenomenon is mainly caused by the following misunderstandings.

Myth 1: I think that all the patterns with appearance characteristics are anti-counterfeiting.

In fact, the following prints do not have anti-counterfeiting features.

1. A pattern created by using a public document downloaded from a public network (material network, forum) as a material;

2. Extract the pattern created by the element from the material library that comes with the anti-counterfeiting software;

3. 寥寥 a few lines, without any difficulty, can only be used as a decorative pattern;

4. Rotate, enlarge, and reduce the regular stripes drawn by the conventional prepress software to form a very regular pattern;

5. Using pirated software, using a constant pattern of output output patterns;

6. In the early stage, I made part of the layout gallery, a pattern that is common on several products.

Misunderstanding 2: I believe that the pattern of the renminbi can be counterfeited, so the anti-counterfeiting pattern used in ordinary goods does not have anti-counterfeiting.

Although some anti-counterfeiting pattern features are difficult for consumers to distinguish between authenticity and falsehood, as one of the anti-counterfeiting combination methods, the pattern has always had strong anti-counterfeiting performance, and can be used for anti-counterfeiting by virtue of its irregularity, anti-scanning and anti-copying properties.

The most typical application cases are banknotes and cards. If you are interested, you can use the RMB 1999 and 2015 100-dollar notes and the space commemorative banknotes to compare the three patterns to see the difference between them.

Misunderstanding 3: Think of security printing and printing Commercial printing is the same.

Anti-counterfeiting printing is special printing, which is different from commercial printing. For example, professional color anti-counterfeiting patterns are scanned according to the pre-press process of commercial printing. Since the image processing software does not have the ability to recognize vector graphics and spot colors, It can only be parsed into a bitmap image, so the slight thickness change of the anti-counterfeiting pattern lines and the color change of the spot color lines cannot be reproduced. The obtained printed matter can be seen by the magnifying glass. The professional anti-counterfeiting pattern is generally composed of lines or blocks. The prints rarely have the concept of dots. Even when viewed under a high magnification magnifying glass, the lines are smooth and flat. The commercial printing method is used to imitate the fake RMB, and the pseudo-pattern is often formed by hanging the net, as shown in Figure 1. The upper left picture shows the magnifying effect of the professional anti-counterfeiting pattern, and the lower right picture shows the printing effect after hanging the net. .
