Abstract:
A method for controlling droplet ejection, wherein droplets ejected from an inkjet print head are to be received on a recording substrate and wherein the print head and the recording substrate are moveable relative to each other, includes determining a set of droplet ejection moments, the set of droplet ejection moments determining when a droplet may be ejected from the print head; moving the inkjet print head and the recording substrate relative to each other; predicting an actual relative position of the print head and the recording substrate at a droplet ejection moment; and determining whether or not a droplet is to be ejected at the droplet ejection moment depending on the predicted actual relative position and depending on the predetermined pattern. Thus, droplets may be ejected from the print head only at stable droplet ejection moments resulting in an increased stability of operation of the print head.
