At present, the domestic gravure printing industry is looking forward to: a single solvent (easy to recycle), surface printing, printing, compounding, cooking and mixing, all kinds of plastic film are suitable, adapt to any climate (can reduce the production of enterprises) Cost), high speed, medium speed, low speed are suitable, low price, and the gravure ink on the universal scale appears on the market.
Advice for ink manufacturers
The printing speed of foreign printing machines is fast, the production environment is relatively standardized, the varieties are large in size and the colors are specific. Therefore, the requirements for inks are limited to high solid content, low viscosity, bright color and strong tinting strength. Most of the domestic low-speed printing presses are mainly used, and the domestic printing presses are uneven and the performance is too large. The products are small in size, various in variety, relatively poor in production environment, and irregular in operation. Therefore, the requirements for the ink are more diverse, and the ink has good adaptability, good fluidity and low price. In addition, due to the operator's mentality, using imported ink, printing problems, choose to adjust the printing press. In turn, printing problems with domestic inks is usually a matter of finding inks and plates.
Domestic gravure printing machines have poor ink circulation systems (except for high-speed printing machines that deliver ink supply), and many medium and small packaging color printing plants do not even use ink circulation systems. Some operators do not understand the ink-inking rules of gravure printing, and have little knowledge of the performance of inks. The ink dilution is not in place (it is observed that the waste rate of ink is 25%~30% on average, and many small-package color printing factories even waste the rate. 40%~50%). What is more needed is to popularize the basic knowledge education of plastic flexible packaging production technology, as well as the technical services after ink sales.
