Abstract:

A method includes forming drops of first size by applying drop-forming pulses during unit time period, τ; forming drops of second size by applying drop-forming pulses during second size drop time period, τm, wherein the second sized drop time period is a multiple, m, of the unit time period, τm=m*τ, and m≧2; providing timing between drops for printing consecutive pixels is equal to τi=a*τwhere a is an integer ≧m and is a function of print media speed; forming the corresponding plurality of drop forming pulse sequences so as to form non-print drops and print drops according to the liquid pattern data; delaying the timing of the drop forming pulses sent to the transducers of the second group relative to the drop forming pulses sent to the transducers of the first group by a delay time τwhich is approximately equal to τ/2.

US Classification:

347 73, 347 74, 347 75, 347 80

Abstract:

A method for operating a continuous inkjet printer, the method includes forming drops with a drop formation period being the time between consecutive drop formations; creating a portion of the drops that strike the print media for forming print drops; creating a portion of the created drops that do not strike the print media for forming catch drops; creating the print drops to print on a series of consecutive pixel locations; wherein a time between the creation of consecutive print drops is inconsistent which causes an additional catch drop so that a gap is created; wherein when a gap is created, adjusting a velocity of the print drop adjacent to the gap to cause the print drop to shift slightly toward the gap.
