Abstract:
1. A method, for use with an inkjet device, of printing an area of a substrate in a plurality of passes using radiation curable ink, the method comprising a.) depositing with the inkjet device a plurality of spaced apart droplets of radiation curable ink onto the substrate in a first pass on the area; b.) partially curing the ink deposited in the first pass such that an exposed surface of the partially cured ink is in non-solidified form, wherein the ink is partially cured with a first dose of radiation from a radiation source carried by the inkjet device; c.) depositing with the inkjet device a second plurality of spaced apart droplets of radiation curable ink onto the substrate in a second pass on the area with the ink of the first pass being substantially wetted by the ink of the second pass; wherein a.) and c.) are performed with the inkjet device in which discrete droplets of ink are deposited from at least one nozzle onto the substrate, the deposition of adjacent droplets of ink are separately controlled to permit mutually different adjacent droplets to be deposited on the substrate; and d.) fully curing the ink on the area with a further dose of radiation after all desired passes of ink have been deposited.
