Patent ID: 7837319

Claim:
A method for use in a digital ink-jet printer, the method comprising: applying a radiation-curable ink to successive locations on a substrate along a first print line in a first direction and applying the radiation-curable ink to successive locations on the substrate along a second print line in a second direction opposite the first direction; concurrently with the application of the radiation-curable ink along the first and second print lines, applying from a single radiation source first curing radiation of a predetermined first intensity to the applied ink along the first and second print lines, with a certain time delay, constant for all the locations on the substrate, between the applications of ink and the first curing radiation, wherein the applying of the first curing radiation along the first print line comprises directing the first curing radiation from the single radiation source toward the second direction, and the applying of the first curing radiation along the second print line comprises directing the first curing radiation from the single radiation source toward the first direction; applying second curing radiation of a predetermined second intensity to the locations on the substrate a certain time period, constant for all the locations on the substrate, after the application of the first curing radiation to said locations.
