How to mix the color of ink? What are the precautions?
Ink hue blending is an important job before printing, but also a very abstract work. Simple color three primary colors, yellow, magenta, cyan can be deployed to red, orange, yellow, green, green, blue, purple and dozens of colors. In the actual blending process, the three primary colors of ink alone can not obtain the color, this is due to the pigments and dyes selected by the ink manufacturer simply can not reach the international standard three primary colors of saturation, color concentration, brightness, etc., three equal parts of the primary colors of ink can only be added to the tea gray, not black. Therefore, in the actual color mixing process can not be separated from the black ink, white ink, watering down agent and other inks and additives.
01 Ink blending process
1.1. master the system, color, color saturation, viscosity, fineness and other indicators of the ink used.
1.2. To validate the sample sheet and customer requirements, process requirements, color requirements, ink use requirements, the arrangement of the color sequence of each color group, the number of product prints, the amount of ink, the deployment of the main colors, etc. to understand in depth.
1.3. Thinner and ink resin solubility, temperature deviation and the ratio of thinner is related, such as high temperature then the thinner should be slow-drying type. At the same time, the dissolution effect, volatilization speed of the product printing quality also plays a very important role, therefore, according to the relevant conditions to choose the appropriate diluent.
1.4. Before printing to do a good job of ink, thinner preparation.
1.5. In the short period of time to start overprinting, according to the color match, the appropriate use of the original color ink, and grasp the ratio, in accordance with the sample sheet for each color group of ink hue deployment, so that after the printing speed is stable, a slight adjustment can be achieved sample sheet effect. In normal printing, batch control of the same color phase, the ink blending staff is more difficult, such as the amount of thinner added will affect the color effect to varying degrees, which requires ink blending staff to have a strong sense of responsibility.
02 Ink blending precautions
2.1. In the case of color tone to meet the requirements, the fewer types of colors used in the ink is easier to deploy and control. Inter-color ink can be used, do not use multi-color ink, according to the subtractive color method, the more colors used in spot-color ink the lower the saturation, the black component will increase accordingly.
2.2. Confirm the main color of the print and the secondary colors contained, the main color ink as the basic ink, other ink as tonal ink, the basic ink as the main, tonal ink as a supplement, so that the deployment of spot-color ink will be faster and more accurate.
2.3. Deployment of proofing and small samples of ink, try to use the same paper used for printing, because the color of the ink will change with the difference in paper absorption and other factors. Only to maintain a stable paper quality, in order to avoid the color error caused by differences in paper.
2.4. With ordinary white cardboard playing small samples or scraping samples, the thickness of the ink layer will directly affect the color of the ink, the ink layer is thin, the color is light and bright. Field or network line, wet pressure wet or wet pressure dry, large or small amount of powder spray, the flatness and whiteness of the paper surface, the thickness of the ink layer and other differences will cause differences in color.
2.5. Tune spot-color ink, first of all, to adjust the saturated hue of the ink, playing a thin sample, to confirm that there is no lack of primary and secondary colors, and then use the watering down agent to the desired spot color.
2.6. The impact of spot-color ink color factors also include the printing process, water, ink control, speed and printing equipment, etc., should grasp the printing and its laws to ensure product quality.
Mastering spot-color ink blending, ink dosage control, the full use of leftover ink, etc., not only to save materials, and personal technical level will have a corresponding improvement. An excellent ink blender, the development of new ink, color innovation, ink cost reduction plays a very important role.
