Abstract
Apparatus for color printing on a moveable receiver includes a re-inkable belt including an ink transfer layer where an ink can be transferred; a structure for causing the moveable receiver to move into proximate contact with the re-inkable belt at a nip position for transferring ink imagewise to the moveable receiver; and an interface capillary spaced from the re-inkable belt and for receiving ink and including pumping structure operating on the ink in the interface capillary for forming a meniscus in such space which engages the re-inkable belt so that ink will be diffused into the ink transfer surface. The apparatus further forms a meniscus when the re-inkable belt passes by the interface capillary to cause ink to diffuse into the ink transfer layer when the ink transfer layer is saturated with ink.
