For the deployment of ink, many companies have their own countermeasures and processing experience. Here are just a few of the issues that should be noted in addition to the operating procedures that must be followed when preparing inks:
1. Keep the surrounding environment clean, wipe with ink wipes, maintain a good working environment, and develop good operating habits.
2. Keep the remaining ink on the machine and do not dry it until it is ready for use. It is best to pour some varnish into the remaining ink and cover it with oil paper.
3. When viewing the hue with a sheet of paper, apply the paper to be printed under standard light or natural light.
4. When dispensing ink, do not use a color ink ink knife to dig another color ink or auxiliary material.
5. When using bottled or boxed ink, do not use ink knife to dig easily. Dig it up on the surface.
6. Never add other auxiliary materials blindly in the ink.
7. For the larger amount of ink, desiccant is best used now, plus how much to increase the quality.
8. Promptly record the proportion of formulated ink so that the ink can be dispensed better in the next printing.
The deployment of spot color inks usually requires a standard chromatogram, a weighing balance, and an ideal mixing environment. According to the hue of the color sample, a corresponding color block is found in the chromatogram, and the ratio of four colors of the four color dots marked by the color block is used to determine the proportions of the yellow, magenta, cyan, and black colors in the original color. Assume that 1000 grams of light green ink is required to be formulated, and yellow (Y) 70% and cyan (C) 20% are indicated in the chromatogram, indicating that the pale green ink is mainly yellow. Assuming a print area of ​​1, the required dilution rate should be 1-70%. The amount of ink used in a batch of jobs is usually related to the following factors:
1) Paper specifications;
2) The area of ​​the image;
3) What is the number of impressions;
4) the type of paper;
5) The proportion of the ink used;
6) Loss.
