Abstract:
1. A radiation curable gel ink spreading method, comprising: heating radiation curable gel ink deposited on a substrate before contact-leveling the ink at a leveling nip; heating the substrate to a predetermined temperature using a substrate heating system; determining whether a substrate file corresponding to the substrate is stored in a memory module, the substrate file including the predetermined temperature that corresponds to the substrate type; if the substrate file is stored in the memory module, inputting the predetermined temperature corresponding to the substrate type to a controller, the controller being in communication with the substrate heating system, to heat the substrate to the predetermined temperature; if the substrate file is not stored in the memory module, inputting a substrate type; inputting a substrate thickness; if the substrate is porous, determining whether the substrate is coated; if the substrate is porous and coated, setting a substrate temperature to a predetermined test temperature; printing a coalescence test pattern wherein the substrate is heated to the set substrate temperature; determining whether a coalescence of the test pattern is acceptable; if the coalescence is acceptable, printing a showthrough test pattern at the set substrate temperature; determining whether showthrough of the test pattern is acceptable; if showthrough is acceptable, storing the set temperature as a predetermined temperature in a substrate file; if showthrough is not acceptable, decreasing the set substrate temperature by a predetermined amount.
