Security label printing

First, micro printing

Micro-printing uses gravure printing to print extremely small text on a dotted line, solid line or single printed dot that is difficult for the human eye to distinguish, or a portion of the shading pattern or embedded in a security line embedded in the paper. This extremely tiny text can only be seen with a magnifying glass or a stereo microscope to see the text, code or image of the micro dot.

Second, the refractive potential

Refractive latent image is a technique for forming shadows by gravure or silk screen techniques. The horizontal or vertical gravure or silkscreen reflection effect is used to make two images on the same part of the paper. When the paper is placed in front of the light source, the horizontal line of the gravure or silk screen is printed, and the projection on the backlight side becomes a visible image, otherwise only the image of the vertical line can be seen. This technology is used in China's newly designed passport.

Third, the seal

The transparent viewing of the two sides of the printed front surface can be completely overlapped, or the partial pattern of the front side can be reformed to form a brand new pattern. A full set of prints, such as the circular pattern under the Hong Kong dollar issued by Standard Chartered Bank of Hong Kong; complementary pairs printed on the d-shaped pattern on the front of the German mark; this portrait is printed on the front of the French franc. In the 1980 and 1990 versions of China, the 5, 2, and 1 yuan patterns on the left front of Braille were also printed.

Fourth, color wiring

When the anti-counterfeit label factory has two or more colors on the same line on the label, the color change wiring is neither separated nor overlapped. To do this, you need high-precision, sophisticated equipment and processes. Some countries in the former Soviet Union and Central Europe have been using their wiring technology called the Olof process, and they can also print multi-color wiring (see the discussion on multi-color serial printing later). This kind of wiring can only be printed by offset printing machine. In early 1957, China developed a flat multi-color wiring printing machine. This machine can complete the docking of four color patterns at the same time. It was used to print the renminbi in 1960, and later invented the gravure printed circuit board printing technology.

1. Embossed print anti-counterfeiting technology: Print-making technology is a special technique that uses special techniques to make different special print patterns from different aspects such as background color, text, and pictures. It not only has anti-counterfeiting effects, but also anti-counterfeiting effects. It is the ideal technology for document and ticket layout planning. Because it can't be re-planned, it can't be scanned into the original map, it can't be forged.

2. Dual-card stealth anti-counterfeiting planning technology: Dual-card stealth anti-counterfeiting technology is the principle of selecting pixel images. The original setting information can be overprinted, so that people can not see the original image. When the dual card is combined, the pixel information on the dual card is replenished into an image because it does not understand the original plan. Various factors, such as angular separation, cannot be scanned into the original map, nor can you copy commonly used anti-counterfeiting printing materials such as paper anti-counterfeiting and anti-counterfeiting additives.

3. Micro anti-counterfeiting planning technology: Micro anti-counterfeiting printing technology uses today's digital copying technology. The principle is to print pictures or text in a miniature way on the surface of the document, which can be reproduced vividly by magnifying the glass picture.

4. Anti-counterfeiting additives refer to special additives processed by special processes, which participate in special anti-counterfeiting information in ink connection guessing, simple implementation, low cost, good concealment and bright color. It is convenient to test (the temperature of the hand can be changed evenly), and it has strong repeatability. It is a technology for anti-counterfeiting of banknotes, tickets and trademarks in various countries. Anti-counterfeiting technology, thermal anti-counterfeiting technology, anti-counterfeiting technology, magnetic anti-counterfeiting technology, dripping stealth technology, liquid crystal anti-counterfeiting technology, printing ink and so on.

5. Paper is the material basis for printing various securities. Special paper made of special technology, anti-counterfeiting features, such as watermark paper.
