Abstract: A method of and system for compensating artwork for coverage gain that occurs during reproducing of the artwork on a reproduction system. The artwork includes one or more graphic elements. The method includes characterizing the reproduction system, selecting one or more graphic elements of the artwork, and automatically modifying the artwork by causing a spread or choke to the selected graphic elements of the artwork by an amount determined according to the results of the characterization step. Reproducing the modified artwork on the reproduction system reduces the coverage gain effects.

Abstract: A composition for a UV-curable inkjet ink that includes none or almost no photoinitiator, and a method of polymerizing one or more such inkjet inks having a viscosity and superficial tension suitable for inkjet printing. The UV curable inkjet ink includes 20-40% by weight of one or more monofunctional acrylates, 35-55% by weight of one or more difunctional acrylates, 5-15% by weight of one or more trifunctional acrylates, no more than approximately 5% by weight of one or more pigments; and a minute quantity or photoinitiator. One embodiment further includes 5-15% by weight of one or more highly reactive acrylates and 0.5-1.5% stabilizer. The method includes depositing the one or more inks on the substrate using one or more inkjet heads in an inkjet printer, irradiating the deposited inks with UV radiation relatively high in UVC radiation (“UVC-rich radiation”), the UVC-rich radiation produced by a first UV source, the irradiation while the substrate is moved relative to the first UV source.
