Image construction system using multiple arrays of drop generators

Abstract

Abstract 10. THE METHOD OF CREATING A PREDETERMINED IMAGE ON A RECEIVING MEMBER SUCH AS A SHEET OR WEB BY SELECTIVE REMOVAL CONTROL OVER A LARGE NUMBER OF SMALL LIQUID DROPS COMPRISING THE STEPS OF: (A) GENERATING A PLURALITY OF LONGITUDINALLY SPACED AND LATERALY EXTENDING ROWS OF LIQUID JETS ALL DIRECTED ALONG PARALLEL TRAJECTORIES IN SPACE, EACH ROW OF JETS HAVING EQUALLY SPACED JETS AND THE ROWS BEING LATERALLY STAGGERED TO PRODUCE INTERLACED AND LONGITUDINALLY EXTENDING DROP DEPOSIT PATTERNS ALONG THE RECEIVING MEMBER WITH THE DROP DEPOSIT PATTERNS LATERALLY ADJOINING AND EACH PATTERN CORRESONDING TO A LONGITUDINALLY EXTENDING LINE OF IMAGE INFORMATION WITHIN SAID IMAGE, (B) MOVING A DROP RECEIVING MEMBER LONGITUDINALLY PAST THE JETS AT A CONSTANT FORWARD SPEED SUCH THAT SUCCESSIVE DROPS IN ANY JET WILL DEPOSIT ON THE MEMBER IN ADJOINING POSITIONS WHEREBY A CONTINUED DEPOSIT OF SUCCESSIVE DROPS WILL PRODUCE AFORESAID DROP DEPOSIT PATTERNS IN ESSENTIALLY CONTINUOUS LINES, (C) STIMULATING EACH OF SUCH JETS AT A COMMON FREQUENCY TO CAUSE EACH JET TO BREAK INTO INDIVIDUAL DROPS OF SUFFICENTLY CLOSE SPACING FOR PRODUCTION OF SAID CONTINUOUS LINES, (D) CREATING WITHIN EACH OF SAID DEPOSIT PATTERNS A SERIES OF NON PRINTED AREAS CORRESPONDING TO NON IMAGED SPOTS IN THE CORRESONDING LINE OF IMAGE INFORMATION, SAID NON PRINTED AREAS BEING CREATED FOR EACH DROP DEPOSIT PATTERN BY TIMED APPLICATION OF AN ELECTRICAL CHARGING FIELD TO THE JET ASSOCIATED THEREWITH FOR CHARGING OF DROPS GENERATED DURING APPLICATION OF SAID FIELD, AND DEFLECTING AND CATCHING THE DROPS SO CHARGED, AND (E) PRODUCING REGISTRATION OF THE NON PRINTED AREAS WITHIN DROP DEPOSIT PATTERNS CREATED BY JETS IN DIFFERENT ONES OF SAID LATERALLY EXTENDING ROWS BY DELAYING THE TIMING OF CHARGING FIELD APPLICATION TO EACH EJT FOR A PERIOD OF TIME EQUAL TO THE TIME REQUIRED FOR THE DROP RECEIVING MEMBER TO TRAVEL FROM THE REARMOST ROW OF JETS TO THE ROW IN WHICH SAID JET IS LOCATED.
