Environmental protection ink UV printing inkjet printer, alcohol and scratch resistant

When the UV variable data jet printing system performs bar code printing, the ink supply system of the UV variable data jet printing system adopts a more stable negative pressure ink supply method. When the nozzle moves up and down, the pressure in the ink cavity of the nozzle is always kept constant, so that The printing is smoother and more stable, and the content printed by the environmentally friendly ink UV printing inkjet printer is resistant to alcohol and scratches. Inkjet printing is a new non-contact, pressureless, and plateless printing technology. It can be printed by inputting the information stored in the computer into the inkjet printing equipment. It also has the common characteristics of plateless digital printing, which can be realized. In the printing of variable information, the ink is sprayed from a fine nozzle onto the substrate at a certain speed, and then through the interaction of the ink and the substrate, the image can be reproduced. There are many types of inks for inkjet printing in UV printing inkjet printers. Even solvent-based inks are subdivided into dozens of types. According to the nature of the ink, there are currently three main types of inks on the domestic market: UV inks and solvents. Type ink, water-based ink. UV ink is a kind of ink that does not use solvents, has good gloss, bright colors, fast drying speed, water resistance, scratch resistance, and alcohol resistance. UV ink refers to the use of light of different wavelengths and energy to make the ink binder under specific line irradiation. The monomers are polymerized into polymers, which can reflect the focus of UV inkjet printers and the advantages of using UV inks. UV ink has a unique curing method, that is, it does not rely on permeation and evaporation to cure quickly. It has been widely used in inkjet printing. UV ink has three major characteristics: energy saving and drying, and wide printing adaptability to the substrate (almost in Printing on all materials), fast curing can shorten the follow-up process time. Water-based inks mainly use water as the solvent, and have the advantages of stable ink color, high brightness, strong coloring power, strong post-printing adhesion, adjustable drying speed, and strong water resistance. Compared with other printing inks, since the water-based ink does not contain volatile and toxic organic solvents, it has no adverse effects on the health of the operators during the printing process, and has no pollution to the atmospheric environment and the printed matter itself. Due to the non-flammable characteristics of ink and wash, it can also eliminate the hidden dangers of flammability and explosion, improve the printing environment, and contribute to safe production.
