Droplet ejection apparatus and method of printing

机译:液滴喷射装置及印刷方法

摘要

A droplet ejection apparatus 1 comprising: one or more droplet ejection heads 10, fixedly mounted in the apparatus, each comprising at least one row of nozzles, each row extending along a row direction and configured to eject droplets; and a deposition media transport system which is configured to transport deposition media 30 in a transport direction x past the fixedly mounted one or more droplet ejection heads such that there is a gap G between the deposition media and the one or more droplet ejection heads. The apparatus further includes one or more gas transfer systems 20, 50 which are configured to carry out at least one of extraction of gas upstream, with respect to the transport direction, and injection of gas downstream, with respect to the transport direction, of each row of nozzles of at least a subset of the one or more droplet ejection heads. The at least one of extraction and injection of gas reduces droplet misplacement caused by gas flows in said gap. A method of printing, using such a droplet ejection apparatus, is also provided.
