Stencils

There are two basic types of stencils available. One type can be made by impression and is thus produced on an ordinary typewriter or dot matrix printer. Since any impression will create a design in the stencil, a metal die can be used to impress trademarks or special logotypes. The limitation of this type of stencil is that, of necessity, it must be fine line. Each impression on this stencil material can produce up to several hundred Electromarks. These are called die impression stencils.
The other basic type of stencil commonly used is made by a photographic process. It starts from black and white art work. Thus any line thickness, broad or fine, and any size character, can be made. Each design of this stencil can produce up to many thousands of Electromarks. The matrix, or base, of the photographic type stencil can be paper or fabric. Thus, a whole series of various stencils is available for different applications. They are called perma or electrolast stencils. It is best to contact the manufacturer for precise recommendations.
These stencils can be pre-formed into caps which fit on any size marker cartridge. Rectangular caps usually mark names and part numbers. The round caps, particularly in the small sizes, are used for inspection stamps.
