ABSTRACT:
A print head of an ink jet printer is formed by a multilayer structure composed of a plurality of individual photoplastic films, segments of such films having a prescribed contour being removed by a photo-chemical treatment being defined on the individual photoplastic films in successive lamination procedures by the use of masks through which such photoplastic films are exposed. Passivation of unexposed films takes place after every lamination procedure by applying a light-absorbing solution. A three-dimensional structure is built up employing photoplastic films having thicknesses in the range between 10 .mu.m to 50 .mu.m and one or more masks having light transmissive regions which define a desired cross-section for the interior passages of the print head.
