Abstract
A method for fabricating a filter element to prevent contaminants from entering an ink supply inlet of an ink jet printhead. The filter is formed by laser ablation process in which output laser radiation is directed through a mask system or light transmitting system to create a filter hole pattern in a thin film. Slightly tapered holes are formed in the film, and the formed filter element is laminated to the ink supply inlet. The tapered holes provide improved flow/impedance and add increased structural strength.
