Dynamic phase shifts to improve stream print

Abstract

A method of forming print drops includes forming drops of a first size by applying drop forming energy pulses during a unit time period, τ; forming drops of a second size by applying drop forming energy pulses during a second drop time period, τ, wherein the second drop time period is a multiple, m, of the unit time period, τ=m*τ, m≧2; providing timing between drops for printing consecutive pixels is τ=a*τwhere a is an integer≧m; forming non-print drops and print drops according to the liquid pattern data; delaying the timing of the pulses for the drop forming energy pulses sent to the drop forming transducers of group number g relative to the drop forming energy pulses sent to the transducers of a first group by a delay time τ, where τ=g*(INT(a/n)+1/n)*τ+τwhere g is an integer<n.
