Method of aperture controlled electrostatic image reproduction or constitution

摘要: THE INVENTION BASICALLY COMPRISES APPARATUS AND METHODS RELATING TO FIELD OF ELECTROSTATICS, IS CONCERNED WITH ELECTROSTATIC REPORDUCING OR CONSTITUTING. APERTURED SCREEN MEANS CARRY CHARGE DISTRIBUTIONS IN ACCORDANCE A PATTERN SUCH THAT PARTICULES DIRECTED AT PASS THERETHROUGH UNDER MOEDULATION CTROL DICTATED BY PATTERN. FURTHER RELATES FOR CONSTITUTING REPRODUCING IMAGES THROUGH USE MULTI-LAYERED CREEEN CONSISTING AN ARRAY APERTURES. PROPULSION DIRECTS CHARGED PARTICLES RECEIVING MEDIUM PREFERABLY SPACED DISTANCE FROM SCREEN. DISTRIBUTION ON CONTROLS FLOW APERATURES, SOME WHICH ARE EFFECT BLOCKED, PARTIALLY UNBLOCKED, ENHANCED, DEPENDING LOCAL LEVEL. THUS, IT POSSIBLE PRODUCE PATTERNS VARYING TONE WITHOUT CONTACT PRINTED EFFECTED SUBSTRATE.
