subject: Topics For: Album Printing Of Special Anti [print this page] 1, paper security Paper is Print The material basis of various securities, some of the special manufacturing process using special paper with security features essentially, a dedicated anti-counterfeiting technology used in the paper are:
1. Watermark paper Watermark paper in the manufacturing process, can make use of technical means to identify needs, patterns and so do into the paper, these patterns easy to see under normal circumstances, only the front of strong light to see, is the security experts around the world recognized as an effective anti-counterfeiting technology, most of the country's bank notes, important international documents, drawings and installations are also a variety of ticket printing paper with a watermark. In addition to the currency paper with a watermark to be used, the paper ticket in the other also has been widely used. The position of the watermark in the paper are fixed, not fixed and semi fixed several. It is a fusion of the manufacturing process
Design , Carving mode, the system net, papermaking and other complicated process, it often makes those who do nothing fake fake. Also looks for a watermark identifying the most effective means of true and false.
2. Safety line Safety line is defined as Papermaking During the process of a gold wire or
Plastic Wire in the middle of the paper. Safety first using a special line of gold thread, is using plastic line and has developed into a diverse, such as mini-letter security thread, fluorescent security lines. The security line shape of straight lines, wavy, zigzag, etc..
3. Or color point of red and blue filaments
Red and blue fibers in the papermaking process or color will be a small piece (point) mixed with paper pulp, or in the paper did not spread on the paper surface before molding, the fluorescence under ultraviolet light reflection. Red and blue filaments and color point in the paper in a fixed position a fixed position and not two.
4. Anti-Copy Paper Copy of this paper, it will emerge, "copy" and "invalid" message, which can effectively prevent color copying important documents. Another total absorption anti-copy paper blue or brown-red appearance, the paper only through the light to see the graphics, the copy of darkness.
5. No special paper fluorescence General paper in the UV irradiation there were significant fluorescence. So Banknote Printing and paper and some securities or instruments are used without special paper fluorescent security. Such as national bank notes, passports and some paper-based ticket no fluorescence, which would also be more readily revealed the additional markings of fluorescent graphics.
2, album printing Such multicolor string printing, multicolor printing string string color printing or also known as rainbow printing, letterpress printing presses generally use more, it is based on printed materials required, place in Mexico slot partition, then repeat it in different Science in the ink were placed in a variety of hues. Ink rollers in the string with a string of action under the adjacent part of the ink to mix and then spread on a plate. Use this printing process can print on a variety of colors, and intermediate soft. Since it is difficult to see the ink on the printed product placement from the slot partitions, it can also play a security role. If printing on large areas of shading using this technology, its security role will be more prominent.
3, anti-counterfeiting printing ink 1. UV Fluorescent Ink Under ultraviolet light, visible light can be issued
Special Ink . 2. Excitation ink Solar discoloration security
In sunlight, visible light can be issued the security printing inks. Color effects, you can never mere mention of purple, blue, yellow and other colors can also be designed to change from colored to colorless.
3. Thermal Security inks (also known thermochromic ink security)
In the heating, the effect of the ink color can occur.
