ABSTRACT:
A method of enhancing print quality of a continuous ink jet printing device and such a printing device in which selected droplets in a stream of droplets are selectively deflected to impinge on a print medium, the method including the steps of providing a plurality of ink droplets, each printing ink-droplet being substantially same size, providing a gas flow that deflects the plurality of ink droplets, monitoring uniformity of the gas flow, and adjusting a flow characteristic of the gas flow based on the monitored uniformity. The step of adjusting flow characteristic of the gas flow is attained by changing flow rate of the gas flow or flow area of the outlet. In one embodiment, the step of monitoring uniformity of gas flow includes monitoring trajectory paths of the deflected plurality of ink droplets.
