UV color inkjet printers were some of the first printers which were invented and they were mainly used in those applications where variable information was required and low production was also a priority. Ideally, most of these printers have the following key components: printer head assembly, drive electronic controllers, curing indicator, motion controlled systems and UV ink.
Initially, two main versions of the UV printers were invented and these were the continuous inkjet (CIJ) printing, which was operating in the continuous stream mode and the piezoelectric or the drop-on-demand (DOD) injects. DODs are not contact printers.
The UV printers have a number of distinct features. Although the two technologies depend on ink to reproduce graphics and images; the principle involved as the ink cures are completely different. The other conventional printers use inks with solvents which are adsorbed by the material which has been printed while some evaporate and thus, the ink dries. The UV inks dry via a photomechanical process. That is, when these inks are exposed to the ultra-violet light, they form solids. This means that there is insignificant evaporation and absorption of the ink’s solvents.
Advantages of UV Printers:
Since the drying process does not involve evaporation of certain elements of the solvent; there are little or virtually no emissions of volatile compounds into the environment. This reduces air pollution significantly.
These printers can be used to print non-porous substances. The ink can dry through photo mechanical process, thus, the drying process does not require any absorption of the ink’s constituents to take place like in the case of the other conventional garment printers.
When you are using UV inks to print garments, its success depends the amount of ultra-violet energy. It is the UV energy which will make this ink to achieve the required level of adherence to the surface which is to be printed.
The other reasons why people opt for the UV Printers Include:
Their ability to produce abrasion resistant surfaces and incredibly crisp texts.
Versatility; these printers offers limitless possibilities since you can print on any type of material, be it wood, metal or plastics. This is for the reason that the UV ink cures without necessarily being absorbed.
Most of them offer some of the fastest printing time in the market, hence, higher rate of production.
They are accurate, offer high resolution and high degree of repeat ability which are key elements of any production process.
There is a lot of research going on in the printing industry with more sophisticated printers being developed to meet the consumers’ endless demands which are ever dynamic. A number of companies are mainly trying to focus on optimizing the performance of the existing UV printers.
