Basic Principles Of Ink Deployment

Darker preparation and Contrast printing: It refers to the preparation of the desired ink slightly darker than the color sample, printing intentionally reduce the amount of ink, so that it reaches the color sample requirements. This is because the hue of the ink is greatly influenced by the thickness of the ink layer. When printing with the same ink, when the thickness of the ink layer changes, the hue presented will also change. Especially when printing is performed by an offset printing process, it is limited by the offset printing process. The ink layer should not be thick.

Use as little pigment as possible: According to the color subtractive method, the more types of color materials used in the preparation of the ink, the darker the color of the formulated ink. Therefore, try to use the smallest color variety to maintain the brightness of the ink color. In addition, we must also make good use of black ink and white ink. In any ink, the addition of black ink will darken the ink, and the addition of white ink will reduce the color saturation of the ink.

Grasp the change of hue before and after ink drying: The hue of the same ink before and after drying is quite different, especially screen printing ink. For example, the deployment of a light gray ink, just adjust the scraping color sample color is in line with the requirements of the original color, but the ink is dry, the color becomes darker. Similar situations occur with other colors of ink.

In order to avoid this situation, the first step is to make the color sample when mixing the ink. After the color sample ink is dried, the color sample ink is dried and then compared with the original color sample to prevent the color of the ink from drying before the color sample meets the requirement of the color sample, and the color is deviated after drying. Loss caused by inconsistent colors.

Based on more: To allocate any kind of ink, first determine the main color according to the original color sample, and use this as the main color to add the auxiliary color until the color meets the requirements of the original color sample. Such as the deployment of light gray ink, white ink should be the main, and then add a small amount of black ink to form a light gray ink. Such as deployment of dark gray ink, black ink should be the main, plus a small amount of white ink to form a dark gray ink. In the actual work, according to the specific circumstances, carefully analyze the composition of the original color ink, determine the main and auxiliary relationship between the ink, in accordance with the "based on more" principle to deploy.
