Abstract: A liquid dispensing element is provided. The element comprising; a dispensing plate comprising a plurality of orifices; the dispensing plate at least partially defining a fluid flow path; a plurality of piezoelectric transducers each comprising a piston configured to move perpendicular to the dispensing plate between a first position wherein the piston is close to the dispensing plate and a second position wherein the piston is further from the dispensing plate. The movement between the first and second positions results in the ejection of a droplet of fluid via a surface cavitation droplet ejection process such that the diameter of the droplet is less than a diameter of the orifice.

Abstract: A method of digitally controlled application and fixation of dyestuff to a textile on a processing line is provided. The method comprising the steps of: determining one or more parameters of a textile; determining, by a processor, at least one dose setting for an array of flow channel dispensers of the processing line, wherein determining the at least one dose setting is based on the one or more parameters; dispensing, by the array of flow channel dispensers, dyestuff onto the textile according to the at least one dose setting and delivering energy to the substrate to fix the dyestuff in the textile.
