Uses in Animation
Ub Iwerks adapted xerography to eliminate the hand-inking stage in the animation process by printing the animator's drawings directly to the cels. The first feature animated film to use this process was One Hundred and One Dalmatians (1961). At first only black lines were possible, but in the 1980s, colored lines were introduced and used in animated features like The Secret of NIMH.
