Abstract
An aperture plate for a print head of a printer can include a first layer having a first emissivity which is covered by a second layer having a second emissivity which is less than the first emissivity. In an embodiment, the second layer can be etched at nozzle locations to form openings in the second layer which have widths/areas greater than widths/areas of nozzles formed in the first layer. In another embodiment, the second layer can have a smaller thickness at the nozzle locations and a larger thickness away from the nozzle locations. Forming the openings in the second layer which are larger than the nozzles, or forming the second layer thinner at the nozzle locations prior to forming the nozzles, can provide a well-formed nozzle and an aperture plate having a low emissivity.
