Hybrid UV Goes Mainstream

After the normal refinements, hybrid UV became an accepted and proven technology that really brought UV technology into the mainstream of sheetfed press configurations. Not just in the U.S., but even the naysayers in Europe embraced it eventually (one even tried to take credit for it).
At that point, it is safe to say that there were basically two established UV offset technologies accepted by the industry. One was full of pure UV; the second was hybrid. Full/pure UV was a pure UV formulation that would run on a UV-prepared machine (EPDM rollers and blankets) 100% of the time. It was very well-suited for nontraditional, non-porous substrates due to its increased adhesion qualities. Hybrid was a “blend” of conventional and UV inks, which utilized normal UV coatings and worked well for a wide variety of applications. Many printers running hybrid would switch between hybrid and conventional inks.
As time progressed, hybrid inks became more and purer UV-like. Combination rollers, blankets, and solvents were developed that worked well and printers added additional interdeck lamps to increase application flexibility.
A few key things to remember: the UV lamp output for the lamps were the same for pure UV as they were for hybrid UV. The ever-important, end-of-press results were also the same, the only exceptions being the occasional adhesion issues that nontraditional substrates experienced with hybrid formulas.
The next development that changed the UV world was the LE (low energy)/HR (high reactive) UV inks and coatings. The concept was to provide just one or two UV “special” traditional lamps with a specially formulated UV ink and coating that were exactly matched to each other. This time it was ink and coating dependent, but also required a traditional UV lamp with special doping to create a different UV wavelength that exactly matched the ink formulation.
Again, it was marketed as a more economical alternative to normal UV in that a printer could possibly use fewer lamps to achieve the goal. Fewer lamps, less supporting equipment and less energy because of that, but requiring more expensive inks and coatings with limited suppliers due to the special ink and coating formulations. This technology is still actively offered in the sheetfed segment of the business, focusing mainly on the commercial market.
Over the past several years, LED-UV has been a term widely publicized throughout the graphic arts industry. Starting out surrounded by lots of energetic marketing along with some truly amazing claims, over time it has gained acceptance across multiple application platforms, including offset, digital and flexo.
LED-UV is a different technology from full/pure UV, hybrid or LE, HR, and HUV, in that the light it utilizes is produced by light-emitting diodes, not a traditional UV lamp. The power output of LEDs are far less than that of traditional UV lamps, so getting the UV energy to the substrate can be a challenge that requires the aid of special optics and/or reflector, even more so in a sheetfed application, particularly in the delivery portion of the press. At the same time, the energy required for the LED system is less than for a traditional UV system.

Successful client Story :

Our Client Mr. Nurzhan from Kazakhstan, we knew each other before one year ago, he owns an advertising company, the whole conversation with him is very pleasant, he is very professional for machines, meanwhile, he is also a technician, after checking all details and video of our printer , he purchased our A2 size UV printer last year . He had used this machine for more than one year till now, everything goes well, just need to come to us to change some spare parts, so once heard we have a new model with 60*90cm UV printer this year , he came to us and buy our new model -WER-EP6090uv , A1 size UV printer again in March.2018
