The
Computer Animation Production System (CAPS) was the first
digital ink and paint system used in animated feature films, designed to replace the expensive process of transferring animated drawings to
cels using
India ink or
xerographic technology, and painting the reverse sides of the cels with
gouache paint. Using CAPS, enclosed areas and lines could be easily colored in the digital computer environment using an unlimited palette.
Transparent shading, blended colors and other sophisticated techniques could be extensively used that were not previously available.
