In response to the increasing need for improved sustainable print solutions, Flint Group Narrow Web is introducing a series of ink technologies for UV LED curing under the EkoCure™ brand. These inks will be the first commercially available inks designed for combination print formulated specifically for UV LED curing.
EkoCure™ is developed using specially selected photoinitiators that match the narrow and targeted wavelength area that is typical for UV LED lamp output. The main advantages with UV LED can be summarized as ecological and economical:
- Ecological benefits – energy will be saved; UV LED lamps are ozone and mercury free (improved worker and environmental safety); EkoCure™ is formulated on bio-renewable resources.
- Economical benefits – energy consumption will be significantly reduced; manufacturing space is reduced; UV LED lamps are nearly maintenance free.
“We have partnered with Phoseon Technology UV LED lamps, and have tested our inks using their FirePower™ 16 W/cm² on our Mark Andy 4150 press in our Center for Technical Excellence in Plymouth, Minnesota” says Tom Hammer, Product Manager Narrow Web North America for Flint Group. Mr. Hammer continues, “With the FirePower units on our press we have been able to experiment and test inks on several types of substrates, and in many print combinations. We have found success and have been able to run a “first ever” true UV LED combination print – using our newly developed 4-colour Flexo process inks in combination with UV rotary screen white.”
Mr. Niklas Olsson, Global Brand Manager, Flint Group had this to say, “The UV Flexo ink series we have developed is based on bio-renewable resin technology as an added effort to address sustainability. Bio-renewable resins for UV products are a new development that will increase in use in the future; by combining this aspect with lower energy consuming UV LED lamps, it was a natural fit to brand this technology as EkoCure™ .“
Mr. Hammer concludes, “We have witnessed great advantages with UV LED lamps as the surface temperature is so much lower; we have been able to run heat sensitive substrates, such as shrink films, without any problem on a press without any special heat management. This we believe is a true added value for many converters, as it is not possible with conventional UV lamps without having special web cooling systems in place.”Tags: UV LED Curing for Narrow-web Applications | Phoseon Technology | Flint Group Narrow Web | Mark Andy
