Sun Chemical Breakthrough at Drupa with Increased Line Speeds for Led Curing Chemistry
“We have seen full cure of ink films, including surface cure, in 12 micron ink films when using 365nm and 395nm wavelength lamps,” said Hartley Selman, SunJet UV ink development specialist. “We can demonstrate full curing with energy doses of 30mJ/cm2 and below which allows the system to effectively run faster, which is what our customer base is demanding if LED curing is to become a reality. We have achieved adhesion to PVC, hard plastics and metals with these inks, so they are functional.”
“Our ink chemists have been able to increase cure speed significantly and apply the speed increases to other SunJet ink families,” said Peter Saunders, sales and marketing manager. “Increased line speed on this scale really widens the scope of LED curing as a method of drying inkjet films. We see application in coding and marking, digital label production, wide format graphics and in variable data printing on plastic smart cards.”
