UV printer

Speaking of UV-LED curing, much has been written about growing efficiency of the technology in every area from affordability to versatility, reports of traditional mercury UV printing’s demise have been greatly exaggerated.

LED curing, just like the LED lighting you can put in your home, is continually becoming more and more cost-effective. However, the UV-LED ink formulations are the challenge. Mercury vapor provides a greater range of curing energy, providing a greater latitude in ink formulations.

For those buying high quantities of printed banners and signs, traditional mercury vapor UV printing is still advantageous. The speed and throughput of these machines are ideal for larger runs and mass production. Mercury arc lamps are the workhorses of the curing industry. But they consume large amounts of energy, are hamstrung by very short lamp life and cannot accommodate as wide a substrate variety as UV-LED printers. In addition, because many countries now ban use of heavy metals such as lead, mercury, and cadmium, printer suppliers have good reason to invest in LED-curing technology, UV-curable and UV-LED inks are dramatically different in both chemical makeup and functionality, UV-curable inks tend to be more aggressive, bonding to a slightly greater surface area. However, these inks are cured differently than UV-LED inks, and thus have a bonding agent that also creates differences. UV-curable inks need a far more powerful light source to cure. Inherently, that light source is also hotter–200 degrees –and therefore more expensive to run. Substrates printed on with UV-curable inks also tend to bubble, buckle, yellow and wave. But adhesion can be better on substrates not affected by the lamps.

UV-LED inks are cured with far less energy and by a light source cool and green,

Overall, UV-LED technology is doing just fine in the marketplace, Hope believes. Lower cost of operation and maintenance along with a longer bulb life and no warm-up or shutdown times are very compelling, Combine that with the lower heat, which minimizes media deformation, and it just makes sense to move to UV-LED technology.

Successful Story :
I am ETABLISSEMENT MARTY from France. I have a printing shop here , we would like to print different clients ‘ designs to glass, wood, metal materials , So we found WER on Alibaba, a golden supplier, after communication with their sales, and saw their machine ‘printing sample and video , I like this machine and printing effect , so I decided to choose A3 size UV printer -WER-E2000UV .
Now I have used this machine for some months, it helps me to do my orders well every day, when my business become better and better, I am going to get a second bigger printer from WER again.
