Abstract
A thermal print head for use in thermal printing apparatus has a pattern of conductive lines for energizing a resistive member overlying a portion of the lines to generate discrete heated spots on the resistive member. A screen-printed protective coating over a portion of the pattern is adapted to reduce the abrasive effect of grit particles carried on the medium to be printed. The coating comprises a layer of dried and fired material formed of a ceramic/glass overglaze composition mixed with fine metallic oxide particles.
