What aspects should be paid attention to in the packaging and printing of food color boxes?

1. On-machine printing:

Most of the color box packaging and printing use offset printing, and the color box packaging is made of cardboard, which is processed and printed, and then folded and pasted with a knife. Cardboard, coated paper and other materials are used for carton packaging; the gift box is made of coated paper, cardboard, art paper and other materials. When printing on the machine, the pressure of the roller should be adjusted properly, and the rubber will be rolled if you are not careful; if the ink color is too heavy, the solid base is too large, and it is easy to stick to glue or ink. Therefore, before printing, the pressure of the cylinder should be reduced, and the rubber of the inner lining should also be reduced, this is done to avoid gluing and rolling. You can add some additives or adhesives to the printing ink, and you should also pay attention to the paper to avoid skewing the paper, and ensure that the pressure is even and the rubber is not rolled.

2. Printing rules:

Color box packaging printing, like other printing products, abides by the printing rules, otherwise it will affect the packaging quality. Bleeding and knife position should be done in the design document, which can save paper and cost during imposition printing. Adjust the nip height of the front, rear, left and right sides of the equipment according to the thickness of the paper, and adjust the pressure of the pinch roller and the brush roller on the output cardboard. After printing is started, if the paper is too thick or too thin, it needs to be checked in time, and the pressure of the pinch roller should be adjusted to ensure that there is no error.

3. Color box packaging printing ink:

Printing ink has a certain influence on the quality of the printed product. When printing, it is necessary to check the amount of printed ink in time, and clean the printed block before to achieve the printing quality standard, because the packaging protects and protects the printed product. The role of decoration, the aesthetic quality of consumers are affected, and even the marketing effect is affected.
