Basic principles of printing color sequence of cup printing machine

Basic principles of printing color sequence of plastic cup printing machine

Plastic cup printing machines have obvious classifications for the number of colors printed. Multi-color and six-color cup printing machines use three principles of water and oil incompatibility, surface adsorption and dot conformation for printing. In multi-color overprinting, the process of using monochrome as a unit, overlapping overprinting in a certain order, and finally restoring to the original is called the ink-color overprinting sequence, or color sequence for short.

The arrangement of the color sequence of the cup printing machine is subject to various conditions. In order to obtain a good printing effect, the following basic principles should generally be followed:

1. Arrange the color sequence according to the lightness of the three primary colors: dark colors are printed first, and bright colors are printed later.

2. Arrange the color sequence according to the lightness and hiding power of the three primary color inks, the ink with poor transparency is printed first, and the ink with strong transparency is printed later.

3. Arrange the colors according to the size of the dot area: Generally, the small dot area is printed first, and the large dot area is printed later.

4. Arrange the color sequence according to the characteristics of the original: the pictures and texts with warm tones are printed first in black, cyan, and then magenta and yellow;

5. Arrange the color sequence according to the model: the color sequence of a single-color or two-color cup printing machine is generally alternating light and dark inks. The printing color sequence of the disposable plastic cup printing machine is generally black, magenta, cyan, yellow or black, cyan, magenta, yellow.

6. Arrange the color sequence according to the nature of the paper: smooth and compact paper is printed with dark color first and then with bright color; while thick and loose paper is printed with bright color first and then with dark color.

7. Arrange the color sequence according to the dryness of the ink: the slow-drying ink is printed first, and the fast-drying ink is printed later.

8. Arrange the color sequence according to the flat screen and the field: the flat screen graphics and texts are printed first, and the field structure is printed later.

9. Arrange the color sequence according to the light color ink and dark color ink: the dark color ink is printed first, and the light color or spot color ink is printed later.

10. Is it convenient to arrange the color sequence according to the rules for matching and changing colors: try to match the main colors or strong colors together or next to each other, and they cannot be separated by anyone. In addition, the color sequence must take into account the convenience of color changing, otherwise it will increase the auxiliary time.

In short, the arrangement of the color sequence of the cup printing machine is a very important and complicated issue. It must be analyzed in detail for specific issues and must not be done blindly.
