UV vs LED UV curing
Understand the differences between traditional UV and emerging LED UV curing inkjet technologies
Understand the difference between UV vs LED curing inkjet technology
UV inks are cured almost instantly by a dose of UV light. Photo-initiators in the ink react and cross link, or polymerise, forming a dry film. Because UV ink cures rapidly, printers can work quickly and economically. There are typically two types of UV curing lamps used in wide format inkjet printers: mercury vapour and LED. Fujifilm’s Dr Carole Noutary explains the differences and challenges in developing UV inkjet systems using UV and LED UV curing technologies.
