Abstract

A screen stenciling device and process for using this device are disclosed. The screen stencil device is comprised of a screening material overcoated with a photoswellable composi-tion. Examples of screening materials include nylon mesh, silk, cotton fibers and wire gauze while the photoswellable material may be a photosensitive material which is subjected to actinic radiation and is heated causing it to expand thus closing the open areas of the screen stencil in the illumin-ated areas. Typical materials include plastics containing proper amounts of photochromic compounds, light sensitive diazo compounds and light sensitive azides.
