Abstract
The invention provides a method for forming ink jet nozzle structures in an ablatable material. More particularly, the invention provides uniform nozzle structure by ablating an ablatable material with a laser beam while setting a field lens unit to various locations relative to a projection lens. The resulting ink jet nozzle structures have substantially orthogonal ink delivery trajectory paths relative to a plane defined by the length and width of the ablatable material regardless of the nozzles hole position relative to the edges of the ablatable material.
