Abstract

Heretofore, technology has been developed for neutralizing the errors in print registration attributable to variations in transit time from nozzle to nozzle in an ink jet printing array. By adding one correction register to the hardware and making a modification to the technique for computing the correction matrix, the allowable transit time error is increased over that described in French application 2375989, published on July 28, 1978. The transit time error was limited to M-K, where M is the number of drop formation periods per cycle, and K is the number of print drops for each picture element. Through the present improvement, the maximum transit time error that can be accommodated is extended to M-1.
