1, security ink: to achieve special printing needs.
At present, many of the anti-counterfeiting inks used in China's tobacco and alcoholic products include the following two: First, the invisible anti-counterfeit labels are printed on paper or plastic film using fluorescent anti-counterfeiting inks, including green, red, yellow and other fluorescent invisible Ink; The second is the use of temperature change security ink, can be blue, purple red, black colorless.
In order to meet the needs of the market, a daylight-type color-changing fluorescent anti-counterfeit ink and a hand-temperature-type color fluorescent anti-counterfeiting ink that can be used for tobacco and wine packaging are introduced to the market. The following are the main features. The first is the use of daylight-type discoloration and hand-warming color-changing high-tech materials that have controllability of raw materials. The second is that the ink has many components, many production equipments, large investment, complicated process, and difficult processing, and it is difficult for most people to copy. The third is to have multiple anti-counterfeiting features, such as intuitive, daylight discoloration, hand temperature discoloration; concealed, fluorescent discoloration. The fourth is the convenience of identification. It can be identified by sunlight or hand temperature heating, and a common UV lighter can also be used.
This new anti-counterfeit ink has the following technical characteristics: First, it uses the principle of chemiluminescence to achieve the uniqueness of fluorescence detection. According to the needs of customers, special patented fluorescent compounds are used, with unique fingerprint recognition function. The only spectrally characterized inks serve the purpose of protecting the product from counterfeiting. Second, the stability of daylight discoloration and hand-warming color fluorescent materials is high, which overcomes the disadvantages of the existing anti-counterfeit inks that are easy to age. The third is the specificity of the proprietary anti-counterfeiting ink formulation lock for commodity brands, that is, according to the needs of customers, the purpose of product protection is to use unique anti-counterfeit ink products that can be characterized. Fourth, new types of security inks can use any printing method to directly print invisible or colored anti-counterfeit graphics on coated paper, paperboard, plastic film and other materials used in tobacco and wine packaging.
2. Electronic Ink: Achieving Digital Offset Indigo's color digital offset press provides a unique combination of features based on its color digital offset press technology and operation. Indigo presses use electronic inks - Indigo's unique liquid inks. Electronic inks contain charged liquid ink particles that make it possible to electronically control the position of printed particles in digital printing. Electronic inks can reach very small particles (1-2 micron), so that small particles allow printing to achieve higher resolution and smoothness, sharpening the edges of the image, and forming a very thin image layer.
(1) Standard basic color CMYK (cyan, magenta, yellow, black);
(2) The wide color gamut six-color setting increases orange red and purple, so that the color reproduction capability is much higher than the color reproduction ability on the basis of the original four colors;
(3) PANTONE compatible Indigo spot color system;
(4) The opaque white coating of the colorless printing material;
(5) Fluorescent ink.
This digital offset technology, with its advantages such as electronic ink, has achieved many advantages:
(1) Edge sharpness and sharpness. From the high magnification results, it can be clearly seen that the image formed by the electronic ink has a sharper degree of sharpness than the image formed by the electrophotographic dry powder. This advantage is even more pronounced when printing continuous images. The sharpness of the electronic ink image is sharper at the edges of the continuous tone image of the intermediate color or the finely printed text image. The clean and pollution-free background of electronic ink images is also worth noting. This advantage comes from the tiny particles of electronic ink and the way the electronic ink particles are transferred during printing.
(2) Dot gains and color consistency. Dot enlargement refers to the tendency of printed continuous blended line images to spread under embossing. Indigo digital color offset printers can control dot gain. Indigo presses have a calibration function that allows printed dots to be within the required size range. In addition, Indigo's printing opportunities automatically adjust the optimal density (such as the darkness of the appearance) and the size of the dots, so that each print has the same appearance.
(3) Image smoothness. Many people think that the key to the quality of offset printing is image smoothness, which is not the case. The key to quality lies in the uniformity of the image. Indigo presses, unlike electrostatic dry powder printers or copiers, can only output images with the same smoothness regardless of the material of the paper. This results in varying degrees of smoothness (such as solid dry powder coverage) and highlighted areas (not covered) in dark areas. Dry powder covered area). The electronic ink image matches the smoothness of the substrate and, like a conventional offset press, produces effects ranging from rough to dull to high brightness. According to different figures and the smoothness characteristics of the offset press, the actual operation shows that the ideal smoothness of the electronic ink can basically meet the requirements of various papers other than super-glossy paper. For moderately smooth paper, electronic ink is more advantageous than lithographic ink, but lithographic ink is superior in the field of ultra-smooth paper.
(4) color difference. Electronic ink can be printed according to international color standards. All of these standards are based on four-color standard basic color CMYK (cyan, product, yellow, black). Lithography uses different ink formulations according to different standards, while electronic ink uses only one set of colors for different standards. The electronic ink adjusts the density of ink (color concentration) through electrons to suit different needs. The special nature of the electronic ink and the charging characteristics of its ink determine its unique features on a four-color basis. In addition to printing the four-color basic color, the electronic ink of the spot color system expands the color gamut to a color gamut that cannot be achieved by the four-color basic color. The spot color ink system is capable of six-color printing, and imaging uses a primary transfer technology.
(5) Instant drying. Because the electronic ink solidifies when it is transferred to the substrate, the finished product will dry when leaving the Indigo press. Electronic inks can be cured without emissions without further drying. At the same time, the electronic ink only needs 100°C, and the relatively low temperature does not allow the substrate to be heated. Damaged or curled.
(6) Do not fade under light. The pigment particles encapsulated in the electronic ink plastic resin will prevent the chemical components of the pigment from being oxidized or affected by moisture. Especially under the intense ultraviolet irradiation of the eyes, the electronic ink has advantages over the traditional offset ink in this respect.
