Spot color ink deployment includes light color ink deployment and dark ink deployment. All in the original ink with a diluent made of ink are light ink, the deployment of diluent based, primary color ink as a supplement. It should be noted that: 1) select the appropriate diluent according to the color sample; 2) determine the proportion of the original ink and diluent according to the chromatogram and the original sample; 3) add the selected primary color ink in the order from light color to dark color; 4) add the ink according to the mixing proportion from large to small; 5) After mixing evenly, scrape a small color sample with a scraper to compare with the original sample, or open the ink on the paper (that is, dip the ink with the volume similar to mung bean on the paper, and then cover it with another paper to compare the ink); 6) use less ink of different colors, otherwise the glossiness of the prepared ink will be reduced and the ink color will be gray; 7) All the paper of the sample should be the same as the printing paper, and the observation of the color draft and the sample must be carried out under the same standard light source. The deployment method of dark ink is basically the same as that of light color ink, but it should be noted that: 1) the main color is the main ink, supplemented by other inks. When mixing, first analyze the light and shade relationship between the main color ink and the auxiliary color ink, then weigh the ink, put the main color ink on the ink mixing table, slowly add the auxiliary color ink and stir evenly, and then observe the difference with the primary color sample by comparison until it is consistent. 2) Select the color close to the requirements of ink, ink. According to the principle of subtraction, the color after mixing will become gray. The more types of primary ink, the darker the color, the lower the brightness and brightness of the color. Therefore, in the deployment of ink, you must choose the color ink with similar requirements to avoid the deployment of a variety of color ink. For example, dark brown is usually mixed with red ink and yellow ink and a little black ink. 3) Pay attention to the color deviation of the ink. Ink usually have some color deviation, such as red, blue, yellow, etc., must control the color deviation of each color ink.4. Matters needing attention in the allocation of various colors of ink, in addition to complying with the operating procedures, the following points must also be paid attention to when allocating spot color ink: 1) ink matching tools such as ink knife and calibration. (2) keep the surrounding environment clean, and wipe off the ink stained area with a rag to maintain a good working environment and develop good operating habits. 3) Take good care of the residual ink returned to the machine. Do not dry the ink for future use. It is better to pour some ink mixing oil into the remaining ink, and then cover it with oil paper. 4) When using paper twist to see the hue, the paper to be printed should be viewed under standard light source or natural light. 5) When matching ink, do not use the ink knife with colored ink to dig out another color of ink or auxiliary materials. 6) When using the ink in barrels or boxes, do not use the ink knife to pick up the ink randomly, but dig the ink layer by layer on the surface. 7) Avoid blindly adding other auxiliary materials in the ink. 8) For the larger amount of ink, desiccant is best to add now, with how much to add, in order to ensure the quality. 9) Record the proportion of mixing ink in time to facilitate the next printing.
