Seven years ago Siegwerk’s ink specialists were the first to demonstrate the use of inks, which had been matched to the specific radiation spectrum of LED UV light, on a Gallus EM 280 at Labelexpo 2009 in Brussels. Today, it is again Siegwerk, which has come up with low migration LED UV inks for food and pharmaceutical packaging as well as label applications on the market, following a series of extensive and successful production tests.
The new Sicura Flex LEDTec ink range is based on the successful Sicura Nutriflex 10 series. “Siegwerk regards LED UV curing as one of the growth drivers in the market. Overall we anticipate a volume-related switch from conventional UV to low migration UV inks in the printing market in 2016,” said Rolf Montag, product manager, Narrow Web Business Unit at Siegwerk Switzerland.
The advantages of LED UV technology are obvious. In contrast to conventional UV emitters that feature mercury vapour lamps, LED diodes only emit the light of a very limited spectral range, which avoids very high-energy IR radiation as well as hazardous UVB and UVC rays. Other benefits include energy efficiency, low heat generation, the long service life of LED UV lamps, as well as zero generation of ozone and therefore there is no need for suction removal. Moreover, UV power is available as soon as an LED UV system is activated, so that the process does not require any warm-up phase. With the motto ‘We color the future,’ Siegwerk will exhibit at Stand A58 in Hall 3 at this year’s drupa.
Packaging South Asia is the cooperating media partner for drupa 2016 which is scheduled to be held from 31 May to 10 June at Dusseldorf, Germany.
