First, we need to know what UV means, in English UV is UV Meaning, so UV inkjet is a new inkjet process that uses UV light curing ink. The simplest statement is a large printer.
UV inkjet differs from traditional inkjet in that it is on the device It has UV ink and UV lamp, which utilizes the components in the UV ink to undergo cross-linking polymerization under the specific wavelength of ultraviolet light, accelerates the film formation of the ink, and achieves sampling, ie, drying, standing, etc. The problem that white ink is not used with color inks has formed a unique artistic style.
UV-jetted patterns are not only concave and convex, but also give people an elegant, The solemn and luxurious visual effects; and the UV ink does not contain or contain a small amount of organic solvents, so the printed pattern has no pungent odor and toxic, and will not damage the substrate, and the precision is up to 1440dpi, comparable to Photo accuracy, and can not fade for 5 years.
1, ink characteristics: (There are three main types of UV inks, namely water-based spray Ink, hot melt jet ink and low viscosity jet ink).
2, UV ink is divided into hard ink (mainly for sheet printing, strong adhesion) ) and soft ink (suitable for soft materials such as leather and PVC are not easy to crack and fall off)
3, strong adhesion, light fast delay, fading, washability, abrasion resistance, High hardness and scratch resistance.
4, low VOC, low energy demand; instantaneous drying; suitable for a variety of substrates ; does not dry before curing; does not block the nozzle; does not need to clean the nozzle; ink composition is stable; high printing quality (light and friction); no pollution.
5, its instant curing characteristics, which causes UV ink to be ejected from the nozzle After that, no ingredients penetrate into the surface of the substrate, and there is no connection with the substrate. Therefore, there is no need to worry that the ink will penetrate into the substrate and affect the surface properties of the substrate.
6, the biggest advantage of UV ink for inkjet equipment is not The nozzle will be cured again, which eliminates the need to clean the nozzle to remove insoluble components. From the industrial production point of view, due to the shortened maintenance time of inkjet equipment, inkjet printing using UV ink can achieve greater production efficiency.
