Abstract
A method for curing of an actinic light sensitive ink or toner layer on a substrate includes irradiating the actinic light sensitive ink or toner layer with a first radiation dose D1 in a first spectral range between 320 nm and 445 nm, followed by a second radiation dose D2 in a second spectral range between 200 nm and 319 nm. The ratio D1/D2 of the first radiation dose and the second radiation dose is between 0.25 and 500, more preferably between 0.25 and 200, even more preferably between 0.50 and 100.
