Security products of the main varieties and performance profiles
One, invisible colorless fluorescent security ink
This is a mature technology, easy to use anti – counterfeiting ink. Usually, it is white or colorless, printed on paper or plastic film does not show color, in the detector or ultraviolet light different varieties will show different colors. It is applicable to the security packaging of official documents, securities, certificates and all kinds of high-grade cigarettes, wine, drugs, cosmetics and other famous brands.
Two, colored fluorescent anti-counterfeiting ink
This anti-counterfeiting ink in the detector or ultraviolet light can show the same color as the original color of the ink, mainly used for bills or other security requirements of printing, there are different colors for the user to choose.
Three, thermochromic ink
Also known as thermal ink, temperature change ink or temperature ink. This kind of ink is divided into three categories: at room temperature, show its specific color, after heating color fade or become another color, cool immediately back to the original color or show white; The second kind of temperature shows the color in the cooling after the cooling will not disappear, because its color change process is irreversible, known as “irreversible thermochromic (hair color) ink”; The third category is called “reversible thermosensitive color ink”, that is, after heating ink from one color to another color, cooling and then back to the original color.
Anti – counterfeiting products of the use of methods and technical requirements
One, invisible colorless fluorescent security ink
The use of colorless fluorescent ink and similar to the use of ordinary ink is basically the same. Usually used directly. Users may also add some solvents or additives as needed, such as:
1, offset printing: mineral oil, ink oil, crude wax, desiccant, slow drying agent
2. Screen printing: 783 thinner, blocking agent, defoaming agent, cyclohexanone, etc
3. Gravure printing: there are three kinds of diluent: slow dry, neutral and fast dry, which can be prepared by users:
A. Slow drying: xylene, butyl acetate, cyclohexanone weight ratio 1:1:1
B. Neutral: toluene (or xylene), butyl acetate, butanone weight ratio 1:1:1
C. Quick drying: toluene, butyl acetate, acetone weight ratio 1:1:1
Colorless fluorescent ink and the same type of four-color version of the ink can be made into a variety of colored fluorescent ink, but the luminous color and brightness will be added to the ink color and the number of different changes, the allocation of improper will affect the ink, the user should be under the guidance of the ink manufacturer, to modulate, or use a special ink.
Users should pay attention to the following points when using offset or gravure colorless fluorescent ink:
1. It is necessary to clean the ink roller and printing plate, the use of new ink roller is more ideal, otherwise, a very small amount of colored ink is also likely to make colorless glossy ink with color, affect the appearance of printing quality.
2. Different paper has different effects on colorless fluorescence. Because most of the paper surface is treated by fluorescent whitening agent, fluorescent whitening agent in the ultraviolet light will give off blue and white light, therefore, in the non-whitening paper (security paper, etc.) and paper containing whitening agent (such as ordinary paper), colorless fluorescent ink color effect is different. It should be noted that it is for this reason, colorless fluorescent blue ink is not suitable for paper containing a strong fluorescent brightener. Otherwise, the blue fluorescence will “drown” in the blue of the brightener.
3. This kind of ink can be printed on the non-pattern part of the printing, also can be printed on the pattern. In order to highlight the fluorescence effect, usually printed on the outermost layer of the pattern.
Two, thermochromic ink
This kind of ink due to temperature change material color concentration is low, so it is best used for the thick layer of screen and gravure printing, and screen printing is better than gravure printing effect. Users shall follow the following precautions:
1. Screen size for screen printing can be up to 500 mesh (under 300 mesh, the printing effect will be better). Gravure seiseido, version lines must be particularly deepened; The solvent used for gravure printing is cyclohexanone, xylene, etc.
2. Screen users can be based on the number of screen mesh and environmental temperature, the right amount of some 783 thinner, plugging agent. Gravure printing, can add xylene, butyl acetate and other solvents, but can not add alcohol and acetone solvents, to prevent the destruction of microcapsules.
3. , because they will react with iron, these two types of ink can not be stored in the iron container. After printing, remove the remaining ink from the press in time.
4. Warm to black and warm to blue can be used to hide other colors. For example, first with ordinary ink printed patterns or text and then with warm black or blue printed on it for cover. When heated, the top color disappears to reveal the pattern or text underneath; After cooling, it is covered again.
New optical color ink to achieve special anti – counterfeiting effect. Optical color-changing inks are the most complex interferometric anti-counterfeiting inks nowadays. The color-changing effect is realized by the light-changing pigments in the inks. Optical color-changing film is formed by depositing each material with different refractive index on the same carrier in high vacuum according to the design requirement of specific film system structure. Once the film thickness meets the light interference condition, a series of light interference effects will occur after being irradiated by light, and its color will change with the change of the Angle of view. As a result of this kind of optical color-changing ink anti-counterfeiting technology compared with other general anti-counterfeiting technology, with a wide range of application area, no need for any instrument identification, printing convenience, secrecy and other characteristics, and thus favored by the manufacturer.
At present, the latest anti-counterfeiting technologies are being promoted and recognized by printing industry, food industry and other industries. These anti-counterfeiting technologies include:
