Abstract
A printing screen, a process of making such a printing screen, and a method of screen printing on hard non-absorbent materials, such as glass, are provided to form a pattern with selected areas of variable thickness. A pattern is formed in the screen utilizing an emulsion coating which has been hardened in the usual manner. A second pattern is formed in a second emulsion coating on a surface of the screen in at least one area of the first pattern. The second emulsion coating is substantially thinner than the first coat and includes a specific dot size and arrangement to achieve additional support, which results in a thinner layer of ceramic ink being deposited when the screen is in use.
