KBA Introduces VariDry LED-UV Sheetfed Press Drying TechnologyMay 15, 2014
- Very low-energy costs to power LED-UV; a savings of up to 50 percent in power consumption and energy costs vs. conventional UV dryers
- No heat on the printed sheet, thus eliminating distortion of plastic substrates
- No spray powders or other chemicals
- Yields more than 15 times the lifespan of conventional lamps
- Flexibility to easily move LED-UV lamps interchangeably on press depending on job printing applications
- Inks can be cured at up to 340 percent total coverage at standard densities
- All stock types can be utilized including gloss and matte coated papers, uncoated offset papers, paperboard for packaging, non-porous synthetic papers, foil-laminated sheets and plastics such as lenticular, as well as most plastic packaging, card and label stocks
- Environmental and safety benefits; UV, HUV, HR-UV or LE UV all rely on mercury lamps; LED eliminates the risk of mercury or ozone contamination and is 100 percent compliant with future bans on mercury for human safety
“We see the immediate future of energy curable presses to be a combination of LED-UV and traditional UV,” remarked Travis. “For example, LED-UV offers a big advantage within the printing units while we will continue to utilize the benefits of traditional UV in the end-of-press dryer to cure coatings. At the Print UV Conference in early March 2014, we had many notable discussions about our technology with interested printers. KBA is at the forefront in this rapidly accelerating transition to LED UV drying as this new technology gains fast acceptance.”
In summer 2014, KBA will be offering live demonstrations of the new VariDry LED-UV curing technology at its customer center in Radebeul, Germany, on presses ranging from Rapida 75, 105, 106 and thereafter on the 145 and is preparing to announce significant LED successes around the world.
