In other words, in traditional animation, they recreate the image so exactly that they can draw exactly the same style without a deviation in the lines themselves? I say this because I have seen animation where the lines squiggle and wave (the Dr. Katz cartoons for example), and I've wondered whether it was done on purpose or if the artist couldn't recreate the image quite as accurately.
Oh, and sorry if I sound like a noob, I've just thought about this a lot.
