ABSTRACT:
A method includes ejecting liquid having a first composition from a first droplet ejection deposition system that includes a first printhead and a first fluid source, collecting information on the behavior of the liquid under a variety of ejection conditions for the first droplet ejection deposition system, and ejecting liquid having the first material composition from a second droplet ejection deposition system that includes a second printhead and a second fluid source under the selected ejection conditions. The first printhead has a small number of flow paths, and the first fluid source is configured to hold a small volume of liquid. The second printhead has a plurality of substantially identical flow paths, each of the flow paths being substantially identical to at least one of the small number of flow paths, and there being a significantly larger number of flow paths in the second printhead than in the first printhead.
