Mimeograph Printing Stencil

This article describes a method of making a new type of stencil that displays superior printing qualities plus more versatility for use.

In carrying out the process, a standard type of mimeograph ink carrier is used. The carrier is coated with polymer plastic such as a polychrome ultraviolet polymer which can be cross-linked by ultraviolet light.

Rather than being typed on the stencil itself, the text, or other intelligence, would be made on material transparent to ultraviolet rays. This finished master is placed against the polymer stencil and exposed to an ultraviolet light source forming the image in the polymer.

The image is now developed and the residue washed away in a well-known manner, leaving a very sharp printing image.

The stencil thus formed is used on a mimeograph machine in the conventional manner.

This process results in a very superior type of stencil which is not subject to bruising, as is the conventionally formed element, when the cutting edge of the type strikes this stencil.

The resulting quality is comparable to offset printing at a fraction of the cost.
