Abstract
An aqueous-based UV-curable fluid composition for use in a micro-fluid ejection device. The fluid composition includes a mixture of poly-functional compounds, a colorant compound, a photo-initiator and less than about 50 weight percent water based on a total weight of the fluid composition, wherein the fluid composition is substantially devoid of volatile organic carrier fluids.
Claims16
A scanning thermal micro-fluid ejection device for ejecting a UV-curable fluid onto a substrate, comprising one or more micro-fluid ejection heads, a structure for scanning the ejection heads across a substrate, a source of actinic radiation, and a shielding device to shield the one or more ejection heads from the source of actinic radiation.
