This is also, one of the oldest methods of printing but it is not used to any great extent.

Stencils made from a thin sheet of metal are costly and less easy to cut with accuracy and more difficult to handle than those made from cartridge paper.

Metal stencils are durable but are liable to damage during working because of their thinness.

It is not possible to cut a perfect circle or a ring or any other complete outline on a stencil plate which if cut, would fall

out of the pattern at once leaving a spot. To prevent this, some form of a tie' is used to link such shapes to the main stencil.

The outlines of a pattern are, therefore, broken at convenient points by cutting the stencil partially; the uncut portions serve as 'ties' to support the inside parts.

Sometimes hair is used to hold to the main. Design those parts or areas that would otherwise fall out.

The ties strengthen the stencil and form an essential feature of the design. Procedure: In actual practice, the stencil is laid perfectly flat on the fabric to be printed and the color paste is then brushed through its perforations with a brush.

The plate is then lifted when the pattern appears on cloth as a colored silhouette corresponding with the cutout! Parts of the stencil.

In patterns with two or more colors. A separate stencil is required for each color as in block printing.
