As has been mentioned here-and-there in this thread, there was a step in between fully-digital art and art that had some level (such as colour) of production done digitally.
For example, in comic books: To my knowledge, the Marvel Epic reprints of Akira were one of the first comics to be digitally colored. This would have been the late 80's. (The original Japanese comics often had the first few pages hand-painted, and then the rest were black and white). IIRC, the artists that formed Image liked how that colouring looked, and had their books done that way too. Then the rest of the industry "caught up".
But... the art was still produced by hand on paper until much more recently. I'm not sure exactly when the switchover occurred, but I'm pretty sure that
most comics are done entirely digitally at this point.
