Abstract:
1. A method, comprising: ejecting liquid having a first composition from a first droplet ejection deposition system that includes a first printhead and a first fluid source, wherein the first printhead has a small number of flow paths, and wherein the first fluid source is configured to be self-contained and to hold a first volume of liquid; collecting information on the behavior of the liquid under a variety of ejection conditions for the first droplet ejection deposition system; selecting ejection conditions based on the information; and ejecting liquid having the first composition from a second droplet ejection deposition system that includes a second printhead and a second fluid source under the selected ejection conditions, wherein the second printhead has a plurality of substantially identical flow paths, each of the substantially identical 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, and wherein the second fluid source is not self-contained or is configured to hold a second volume of liquid larger than the first volume.
