Abstract: A curing method in UV-curable inkjet printing uses a combination of a partial curing followed by a final curing step. The printing is organized in a first set of printing passes during which partial curing takes place, followed by a second set of passes during which no partial curing takes place. The method apparently suppresses gloss banding artifacts.

Abstract: A method for making a lithographic printing plate is disclosed wherein the method comprises the steps of: (i) providing a negative-working lithographic printing plate precursor comprising a photosensitive coating on a substrate having a hydrophilic surface, (ii) image-wise exposing said photosensitive coating, (iii) developing said exposed coating to form an image on said substrate and optionally gumming the plate and (iv) baking the image on the plate, wherein said baking step is carried out within a dwell-time of less than 1 minute and wherein the chemical resistance of the coating against printing liquids and press chemicals is improved. This baking step is preferably carried out by exposing the printing plate to an infrared radiation source, preferably in a dynamic configuration.
