is any material that protects areas of a work from unintended change.
On a sheet-fed letterpress printing
Letterpress printing is relief printing of text and image using a press with a "type-high bed" printing press and movable type, in which a reversed, raised surface is inked and then pressed into a sheet of paper to obtain a positive right-reading image...

to coat the surface of the type with ink, the ink brayer will often coat the furniture
(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
In hand-operated letterpress printing, the bruzer tympan is the taut cloth or paper mounted in a frame which is placed over the sheet of paper immediately prior to lowering the platen to make the impression....

A new frisket has to be cut for each different page or form; a well-made frisket lasts for hundreds or thousands of impressions.
In airbrushing, a frisket is a plastic sheet with an adhesive backing used to mask off
In art, craft, and engineering, masking is the use of materials to protect areas from change, or to focus change on other areas.Masking can describe either the techniques and materials used to control the development of a work of art by protecting a desired area from change; or a phenomenon that ...
specific areas of an image so that only the exposed area is covered with paint. The frisket is vital to airbrushing, because it allows the artist to control excess paint spray, create special effects, achieve extreme precision, control edge attributes and to expedite the airbrushing process.
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

-proof, manufactured for use with solvent-reduced and -based Urethanes.
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.
An airbrush is a small, air-operated tool that sprays various media including ink and dye, but most often paint by a process of nebulization. Spray guns developed from the airbrush and are still considered a type of airbrush.-History:...
