A cel, short for celluloid, is a transparent sheet on which objects are drawn or painted for traditional, hand-drawn animation. Actual celluloid (consisting of cellulose nitrate and camphor) was used during the first half of the 20th century. Since it was flammable and dimensionally unstable, celluloid was largely replaced by cellulose acetate.
There are similar techniques that can make an image look like a sketch, an oil painting or an ink painting. The name comes from cels (short for celluloid ), clear sheets of acetate which are painted on for use in traditional 2D animation .
In airbrushing, a frisket is a plastic sheet with an adhesive backing used to mask off 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 expedite the airbrushing process.
The animation photo transfer process (APT process) was a photographic transfer system that can photographically transfer lines or solid blocks of colors onto acetate sheets . A similar process is used in making the stencils for silk screen printing.
Stencils are usually applied in the home with a paint or roller brush along wall borders and as trim. They can also be applied with a painted sponge for a textured effect. Stencil templates can be purchased or constructed individually. Typically they are constructed of flexible plastics, including acetate, mylar, and vinyl.
Such systems were originally mechanical, using drawings or photographs printed on transparent acetate sheets that could be superimposed on one another to produce the composite image. The first such system was the drawing-based "Identikit" which was introduced in the U.S. in 1959. [ 2 ]
Don’t let the complicated name fool you: polyvinyl acetate is another term for wood glue, white glue, carpenter’s glue, and school glue. A rubbery synthetic polymer with adhesive properties ...
Overhead projector in operation, with a transparency being flashed. A transparency, also known variously as a viewfoil or foil (from the French word "feuille" or sheet), or viewgraph, is a thin sheet of transparent flexible material, typically polyester (historically cellulose acetate), onto which figures can be drawn.
