Grasping the gloss of the printed ink film is the key to success

June 01, 2024
The gloss of prints is a kind of popular beauty. The gloss of printed materials is not a difficult problem with the continuous innovation and improvement of printed materials and printing machinery. However, some manufacturers often can not meet the customer's requirements for the luster of printed materials, gloss and color, the same can produce a corresponding response to human psychology, especially in the evaluation of print quality occupies an important position, then how should we improve the printing ink film Gloss it?

In the ink color, it should generally pay attention to observe the color sample, pay special attention to observe the printed substrate, select the ink from the rough and smooth reflection degree of the substrate. For example, inks are printed on smooth, highly reflective aluminum plates or cans. Choosing high transparency inks will help enhance the metallic luster of the ink. When selecting the ink required for color matching, avoid mixing too much ink as much as possible. Use inks that are close to standard colors and made from a single pigment. The more color inks are used for color matching, the farther from the standard color, the worse the brightness and the higher the degree of matteness of the mixed colors. It is not possible to modulate the primary colors by color matching.

Also need to add white. When black ink is used, special attention should be paid to the accuracy of the added weight and weighing. In all inks, the hiding power of black ink is extremely strong, and adding too much will not only dilute the color, but also will prevent the reflection of the substrate. However, for the printing of rugged substrates such as nylon or paperboard, it is best to print a white layer that serves as the background color in order to ensure the appearance of the print. Due to the strong coloring power of black ink, adding too much carelessly to the black ink requires adding a large amount of other color inks to adjust the color and cause waste. So pay special attention.

In general, the method of improving the gloss can be started from these few aspects:

1. Add appropriate amount of varnish within the allowable range of color concentration.

2. Apply a varnish or varnish to the surface of the printing ink film.

3, increase the ink transparency, such as the use of high transparency of the highlight ink or adding the right amount of varnish, the use of smooth reflection of the substrate to enhance the shine.

4, to prevent the substrate surface adsorption, and reasonably improve the smoothness of the substrate printing surface.

5, pay attention to the temperature of the printing environment.
