Abstract: A perforate element (101) for use in a print head for non-contact liquid printing comprises: at least one ejection element (103) including an outlet (103a), configured to eject a bulk flow (F) of printing liquid (L) out of the print head; and a liquid residence element (107), arranged to provide a layer of liquid over the outlet (103a) which extends laterally of the outlet (103a) and through which the bulk flow (F) is ejected.

Abstract: A mixer system for use with a non-contact liquid printer comprises: a printing liquid reservoir (103) and an expansion volume (105); and an aspirator element (111; 311; 411), configured to reduce the pressure in the expansion volume (105), thereby to displace printing liquid (L) from the reservoir (103) to the expansion volume (105), and restore the pressure in the expansion volume (105), thereby to return the printing liquid (L) to the reservoir (103) so as to mix the printing liquid (L) therein.
