Traditional Animation// CEL

CEL or celluloid is typically a transparent sheet on which traditionally animated sequences are traced onto or printed onto; this technique is primordially used to add colour or to add 'layers' to the animated sequence.

Normally the 'line' of the animation is drawn/printed on one side then the page is flipped and colour is added to the second side. It had only been since the late 1960s where the frames for the animation have been printed on, traditionally they were hand traced with ink by trained professionals for this purpose. The first artist credited for this technique is Earl Hurd who practised publically with using CELs in 1914.
