Abstract
Aspects of the present disclosure are directed to forming a layer of material on a print head. As may be implemented in a manner consistent with examples herein, a layer of material from a transfer film is pressed against a surface of a print head, in which the surface defines fluid nozzle openings that extend from the surface into the print head. Portions of the material pressed onto the surface are therein adhered to the surface and caused to wrap over edges of the surface extending around the openings. The transfer film is removed along with a thickness of the material pressed into contact with the surface that remains adhered to the transfer film, as well as some or all of other regions of the material over the openings. The remaining layer of the material on the surface is thus formed with a uniform thickness.
