Abstract
Nozzles are formed in a plate for an ink-jet printer by holding a metal foil tightly against the side of the plate from which the nozzle is to protrude, and then pressing and punching through the plate and the metal foil together, through an aperture of a pressing die into a cushion of a hard elastic material such as lead. The foil is made of an isotropic material which is harder than that of the nozzle plate, and is preferably an amorphous or microcrystalline metal.
