Patterned metallization on polyimide aperture plate for laser-ablated nozzel

A print head aperture plate, comprising:

• a first layer having a first emissivity and comprising at least one opening therein defined by an edge of the first layer;
• a second layer over the first layer, the second layer having a second emissivity which is lower than the first emissivity and comprising at least one opening therein defined by an edge of the second layer, wherein the edge of the second layer is targeted to be vertically aligned with the edge of the first layer;
• and
• at least one nozzle extending through the first layer and through the second layer,
• wherein the at least one nozzle has an edge formed by the edge of the opening in the first layer and the edge of the opening in the second layer, and a first thickness of the second layer exposed at the at least one nozzle edge is less than a second thickness of the second layer at a location remote from the nozzle edge.
