METHOD OF TREATING INK ON POROUS SUBSTRATE USING PARTIAL CURING AND APPARATUS USEFUL IN TREATING INK ON POROUS SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide methods of treating ink on a porous substrate, and to provide methods of printing onto porous substrates.;SOLUTION: An exemplary embodiment of the methods of treating ink on a porous substrate includes steps of: applying a layer 156 of ink onto a first surface of a porous substrate 150; irradiating the layer of ink with first radiation having a first spectrum effective to partially cure the ink layer and reduce entry of the ink into pores of the substrate; leveling the partially-cured ink layer; and irradiating the as-leveled ink layer with second radiation to further cure the ink layer, the second radiation having a second spectrum different from the first spectrum of the first radiation.;COPYRIGHT: (C)2012,JPO&INPIT
