The gravure printing industry is referred to as gravure printing. Gravure printing is one of the four major printing methods. It is named after the printing plate, that is, all printing patterns and characters are recessed on the printing plate. The excess ink on the printing plate (the ink on the non-printing surface) is scraped off, and then an appropriate pressure is applied to the printed packaging bag between the printing plates through the embossing rubber roller, and the ink is squeezed from the concave surface to the packaging bag A printing method that achieves the purpose of printing.
What are the characteristics of gravure printing for plastic packaging bags?
1. The inking amount of gravure printing is determined by the depth of the concave part of the image and text on the curved printing plate. During printing, the depth of the concave part of the image and text is relatively fixed, so the inking amount remains relatively stable;
2. The inking method of gravure printing is that the printing plate cylinder is directly immersed in the ink tank to receive ink, or the ink is applied to the printing plate cylinder by the ink transfer roller, which saves a lot of ink transfer rollers and ink volume adjustment devices;
3. The ink transfer volume of gravure printing is larger than that of offset printing and flexographic printing, so the ink layer of the product graphic is thick and the three-dimensional effect is strong;
4. Most gravure printing is rotary printing, with fast speed and strong ability;
5. The range of gravure printing materials is wide, and it has good adaptability to materials that are easy to extend and deform, such as plastic packaging bags and composite materials;
6. Gravure printing is printed with ink that is prone to dryness and non-absorbent plastic packaging film. Dongguan Yuli’s packaging is fully printed with gravure, and the colors are more beautiful and accurate.
