Abstract

A porous coating applied to a nonporous type element provides a suitable reservoir for ink, which enables multiple impacts with a single inking. Coating 1 is applied to solid character 2 formed on the surface of element 3 by flame spraying. The coating is thin enough to retain the desired character definition, and a material such as aluminum oxide or molybdenum provides a durable surface on the character. Flame spraying produces a porosity which facilitates ink retention, while yet permitting necessary flow to the character surface for printing.
