Abstract

1533659 Ink drop printers IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Dec 1975 [24 Dec 1974 24 June 1975] 55762/74 and 26789/75 Heading G4H An ink drop printer includes means for modifying (e.g. decreasing) the charge to be received by a drop so as to compensate for one or more of the following (a) the effect on the charging process due to one or more preceding drops not being required to be printed (and being treated accordingly in the charging process); (b) the effect of an altered aerodynamic interaction on the flight path due to one or more preceding drops not being required to be printed; (c) the effect of altered electrostatic interaction between drops due to one or more of the preceding or subsequent drops not being required to be printed; said means being controlled in response to input data relating to the drops. As disclosed, data for a given drop is compared with data for 3 preceding and 1 following drop to derive 4 bits (each specifying equal or not) which together with 4 bits specifying the current step of a charging staircase, address a read-only store to obtain a number which, via a D/A converter, corrects the charging voltage (by being subtracted from it).
