ABSTRACT:
This invention relates to an improved design associated with the fabrication and construction of a self-contained ink applicator capable of enabling the continuous printing upon non-absorbent surfaces, said self-contained ink applicator comprising an exterior housing having a reservoir containing a porous material which is in direct contact with a porous rigid supporting member which in turn is in direct contact with a porous rubber die which conveys the desired imprinting sought upon non-absorbent surfaces, therebeing initially impregnated into said porous rubber die a solvent capable of enlarging the cell structure thereof in a controlled fashion so as to permit the utilization of inks capable of imprinting on non-absorbent surfaces, the above being achieved after initially impregnating said porous rubber die with said solvent to then immediately thereafter impregnate said porous rubber die with an ink composition that has contained therein said solvent thereby maintaining the expanded cell structure as referred to above, the reservoir additionally containing said ink composition that has contained therein said solvent.
