Abstract

An electrolytic print head comprises a plurality of styli (16, 18) between electrically insulative laminae (38, 42, 48, 38', 42', 48') which space the styli from planar reference electrodes (20, 22, 24). The styli and reference electrodes are fabricated of a mixture of ruthenium dioxide and corrosion resistant glass, and the insulative laminae are fabricated of corrosion resistant glass. The method of manufacture of the print head facilitates use of styli and reference electrodes requiring high temperature processing prior to deposition of metal conductor tracks for the styli and reference electrodes.
