Abstract
A high density printer includes a printing plate having an array of through holes of capillary dimension, and individual heaters located within each hole near one face of the printing plate, whereby printing is accomplished by placing the other face of the printing plate in contact with a pool of liquified phase change ink for a period of time sufficient to allow ink to fill each hole via capillary action, after which time the printing plate is removed from the ink and allowed to cool for solidifying the ink within each hole, whereafter selective ones of the heaters are energized for melting ink in associated holes, whereupon the ink expands away from the solidified ink in the portions of the holes below the heaters, causing ink to protrude from the associated holes on the one face in a desired pattern for transfer to a substrate brought into intimate contact with the one face.
