The color of packaging and decorating prints requires a strong physical sense. Therefore, the selection and deployment of ink colors is very important. In theory, no matter how colorful the ink color is, it should guide the machine printing with the color when the cans are opened. However, in actual printing, the color of the ink when opening the can often does not meet the requirements of the color of the draft, and due to various factors such as the process method, environmental conditions, and substrate materials, the printability of the ink when opening the can is sometimes also not ideal. Therefore, when printing, it is often necessary to adjust the ink fluidity, drying property and viscousness with various ink additives according to different situations. Such as: add varnish, dry oil, dilute agent, remover and so on. The following combination of work experience, talk about a few issues related to ink deployment.
First, the ink color matching Toner workers must understand the basic specifications of color matching, as well as the type of ink and the ink itself. Otherwise, the color of the mixed ink may not reach the customer's requested color sample effect. In color matching, ink color should be formulated according to the actual printing process, ink layer thickness, printing material and other conditions. When choosing the ink color, consider the gloss, hue, tinting strength and hiding power of the ink. In addition, in order to adapt to the needs of the printed products, when the color inks are prepared with the primary color inks or the spot color inks are prepared, appropriate processing is required to obtain the suitability for printing.
In a specific color palette, first of all, the composite ratio of the main color and the auxiliary color should be identified. Different proportions of primary inks can be mixed to produce different ink color effects.

The distribution ratio of light ink is as follows:
Pale red ink: mainly 8011 or 8015 lighter, slightly increase red, orange;
Five-color ink: mainly 8011 or 8015 lighter, slightly orange, yellow;
Gray ink: mainly 8011 or 8015 lighter, slightly black ink;
Light blue ink: mainly 8011 or 8015 lighter, slightly silver, black ink;
Lake Green Ink: mainly 8011 or 8015 lighter, slightly add Kong Lan and Zhong Huang;
The preparation of the ink should be carried out from light to dark, and the pale ink (dissolving agent) cannot be mixed on the basis of the dark ink. The color of dark-to-light deployment ink is not easy to grasp, and it is easy to cause excessive ink consumption and even rework. The dark ink should be gradually added based on the pale ink (disposal agent), and the color samples should be tested repeatedly until the color meets the requirements of the original. With a good ink sample, you can get the mixing ratio of the main color of the ink and the auxiliary color, and then determine the production requirement of the ink according to the layout, paper, number of prints, and process requirements of the print.
The color of the ink is blended with the primary color or the inter-color ink, which can be corrected with its complementary color. For example, when the tuned ink is too purple, it can be corrected by adding red color; when the blue taste is too heavy, orange ink can be used to correct. In addition, prints that require quick drying can be diluted with 8019 lightening agent to achieve a fast drying effect.
Second, the adjustment of the ink printability General properties of offset inks can be seen in Table 2. Table 2 ink characteristics table

(1) The adjustment of the degree of ink thinness must be such that the fluidity, thixotropy, and other properties of the ink used in the production of the ink meet the printability. The original ink is thicker and sticky, and it is usually not suitable for direct printing on the machine. Because the ink viscosity is too large, the ink in the ink fountain cannot accommodate
