Douga

A douga is the clean up sketch, basically the gengas are sent to the douga-men, to be cleaned up and basically retraced on clean white paper with the sketch number moved to the top right corner.  These sketches are what finally makes it to the screen, if it is a computer animated show the sketches are scanned and then digitally colorized if we are talking a show pre-2001 they are then made into Cels.
