The first UV inks at drupa 1976 versus LED UV at drupa 2016
UV LED curing at drupa 2016
UV curing will have a prominent place at drupa 2016. Various systems, from ….. to super format inkjet printers will make use of the ample experience with this curing technology our industry has, more than 40 years. Thanks to the invention of light emitting diodes, LEDs, we now have a cost effective and controllable energy source to cure inks fast and without warmth. That is however not an easy process. Many factors influence the the quality of the curing as well as of the actual print. The distance between the LED and the media is important, as well as the composition of the suitable inks. More information about UV curing in general and specifically LED can be found in RadTech´s whitepaper which can be downloaded from our downloads page. RadTech International is an organisation of companies dedicated to UV and electron beam curing systems.
UV LED for offset on demand
Following the UV LED for sheet offset presses by pioneer Ryobi, many of the larger manufacturers will show their offset presses with UV LED curing at drupa. Not just the small or mid size format presses. We do not yet know if KBA will show its Rapida 145, the first large format press with UV LED curing, is not known yet. MAN with its Roland 700 HiPrint and Heidelberg with its Speedmaster XL106 will emphasise the UV LED breakthrough. UV LED curing, in combination with short make ready times, give printers the possibility to be competitive in small jobs. Digital printing technology as a kind of offset on demand. And if these printers have a good workflow, the choice between offset and digital is a simple one, based on price and production time. Offset still has the advantage with jobs of more than 300 prints, especially on the 70x100cm presses which are able to very efficiently combine different jobs. Something which internet printers prove on a daily basis.
Production inkjet and UV LED
So, this year at drupa 2016, try to look at these digital print monsters from a different perspective.
