ABSTRACT
Digital Ink and Paint Years ago our only option for painting animation drawings was to trace the drawings with ink onto clear plastic celluloid sheets, or cels. Then the colors were painted, one at a time, onto the back of each cel. The cels were then stacked on racks to dry and took up a great deal of space. As clear as the cels are, they could only be stacked to 6 or 7 levels due to a slightly increased loss of light and color with each layer (Figure 31-1).
