Sun Chemical Breakthrough at Drupa with Increased Line Speeds for Led Curing Chemistry
DÜSSELDORF, GERMANY—June 2, 2008 – SunJet, the inkjet ink division of Sun Chemical, has announced at drupa the development of new and novel ink chemistry specifically designed for curing under exposure to UV light from LED sources. In laboratory tests line speeds in single pass applications have exceeded 100m or 300 ft. per minute. SunJet is present on the Sun Chemical stand at drupa 2008, Düsseldorf from May 29 to June 11, in Hall 6, Stand B75.
SunJet is a leader in the development of UV curing inks and has supported the industry developments in LED UV lamp technology for several years and was one of the first ink companies to recognize the potential benefits to customers of inks which have the ability to part cure or “pin” with UV LED lamp exposure in scanning head systems.
As lamp technology has advanced and higher power lamps have been demonstrated, SunJet has managed to produce graphics inks which fully cure with LED UV exposure. What is announced at drupa is a further step change in performance and in application.
In the last two months, SunJet has produced a set of inks designed for use in single pass applications which raise the achievable line speed by more than three times. In addition to this improvement SunJet has discovered a route in formulation which allows the increased response to LED UV output to be applied to a full range of SunJet ink families. This means that popular ink sets such as SunJet’s flexible inks can be used with the new LED lamp technology if correctly integrated.
LED lamp technology is important because it can reduce the complexity of integrating UV curing lamps, can reduce the environmental and health and safety concerns in some applications and also allow use of UV curing technology on heat sensitive substrates.
