 to coat the surface of the type with ink, the ink brayer will often coat the furniture and slugs (wood and metal spacers) between the columns and around the type. To keep this ink from touching the target sheet, the frisket covers the area that is not desired to print. The frisket is set in a frame, often hinged to the tympan

A frisket differs from other masks in that it is a single sheet that covers the entire work, parts of which are removed by cutting into the sheet. Friskets are available in matté and glossy finishes. Some friskets are also solvent

The frisket is fixed to the painting surface and then the appropriate shapes are cut out of the material using a razor or scalpel. The cut piece is lifted, the exposed area painted, and the process repeated using the cut pieces to mask their matching finished areas. When all painting is finished, the resulting work contains precise shapes with no overspray.
