Animation photo transfer process
Type of technique used in animation
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 (cels). A similar process is used in making the stencils for silk screen printing. The process relies on UV-sensitive inks that cure when exposed to light and stick to the plastic sheet, while the ink in the non-exposed areas is chemically removed from the sheet.
