Abstract

When utilizing anodized aluminum as an ink carrying printing surface, it is desirable to extend the life of the surface to a maximum number of impressions. On a normal water-sealed aluminum oxide surface a thin ink repellant film appears to form on the surface reducing its effective life. A method which eliminates this apparent incompatability of water-sealed anodized aluminum for ink consists of sealing the anodized surface with the ink to be used in the printing process instead of with water. This is accomplished by submerging the unsealed anodized aluminum surface in the ink at an elevated temperature. The effective life of the printing surface is increased by a factor of about five hundred over the number of impressions obtainable by a water-sealed surface.
