<p>A novel pad printing method and machine employ a disposable ribbon (12) of a microporous, readily inkable material on which a programmable inkjet head (8) defines an inked ink impression which is thereafter picked up by the pad and transferred onto the workpiece in a usual manner. The method and the machine allow an outstanding control of both specific consumption of ink and of noxious ink vapor emissions. Progressive numbering may be easily programmed, avoiding the use of troublesome clichés incorporating updatable mechanical numerators. Multicolor printing is readily performed without a large inventory of clichés. <IMAGE></p> |
