    The deployment of ink color is an important work before printing, but also a very abstract work. Simple color material three primary colors, yellow, lich, green adjustable with red, orange, yellow, green, blue, purple and other dozens of colors. In the actual deployment process, only rely on the three primary color ink can not obtain the color, this is due to the ink manufacturers selected pigments, dyes simply can not meet the international standard three primary color saturation, color concentration, brightness, etc. , the three original color ink can only be tea gray, not black . Therefore, in the actual coloring process can not be separated from black ink, white ink, lighteners and other inks and additives.
    01 Inking process
    1. Master the ink used system, color, color saturation, viscosity, fineness and other indicators.
    2. To sample and customer requirements, process requirements, hue requirements, ink use requirements for the review, for each color group color sequence arrangement, product printing, ink dosage, the main tone of the deployment to be in-depth understanding.
    3. The ratio of diluent to the solubility, temperature deviation and thinner of the ink resin is related, and if the temperature is high, the diluent should be slow-drying. At the same time, the dissolving effect and volatilization speed also play a very important role in the printing quality of the product, so the appropriate thinner should be selected according to the relevant conditions.
    . Before printing, do a good job of ink, thinner preparation.
    5. In the short time of power-on overprinting, according to the color matching, the appropriate use of raw ink, and grasp the proportion, according to the sample of each color group ink color adjustment, so that the printing speed is stable, a little adjustment can achieve the sample effect. In normal printing, batch control color is the same, for ink-tuning personnel more difficult, such as the amount of thinner addition will affect the color effect to varying degrees, which requires ink-tuning personnel to have a strong responsibility.
    02 Ink-tuning notes
    1. In the case of tonal compliance with the requirements, the fewer types of colors used, the easier it is to provision and control. Can use intercolor ink do not use complex ink, according to the color reduction method, spot ink using more colors its saturation will be lower, the black composition will increase accordingly.
    2. Confirm the main tone of the print and the auxiliary tone contained, the main tone ink as the basic ink, other ink as the color ink, to the basic ink-based, color ink as a supplement, so that the deployment of spot-color ink will be faster and more accurate.
    . When you provision samples and small sample inks, try to use the same paper as the paper used for printing, because the color of the ink varies with factors such as paper absorption. Only by maintaining a stable paper quality can color errors caused by paper differences be avoided.
    4. With ordinary white paper jam small sample or scraping sample, the thickness of the ink layer will directly affect the color of the ink, the ink layer is thin, then the color is light, brightness is high. Field or net line, wet or wet pressure dry, spray powder amount is large or small, the flatness and whiteness of the paper surface, the thickness of the ink layer and other differences will cause color differences.
    5. Tone spot ink, first of all, to adjust the saturated hue of the ink, play a thin sample, confirm that there is no lack of main tone and auxiliary tone, and then use a lighter to adjust to the desired spot color.
    6. The color factors affecting spot ink also include printing process, water quantity, ink control, vehicle speed and printing equipment, etc., should grasp the printing and its laws to ensure product quality.
    to master the deployment of spot-color ink, ink amount control, the full use of leftover ink, not only can save materials, but also the level of personal technology will be correspondingly improved. An excellent ink adjuster plays an important role in the development of new inks, color innovation and the reduction of ink costs.
