Frisket

To keep this ink from touching the target sheet, the frisket covers the area that is not desired to print.

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 expedite the airbrushing process.

The frisket is fixed to the painting surface and then the appropriate shapes are cut out of the material using a razor or scalpel.

Frisket is usually used when the unmasked areas are desired to be the same colour and a rapid wash is being applied, or for negative painting effects.

Some lesser grades of paper, often used for practice and academic purposes, may be more prone to damage after repeated masking and painting cycles, however.
