A computer-based method of processing a computer graphics illustration having overlapping pieces of artwork includes mapping one or more pieces of artwork having a degree of transparency onto a grid, mapping at least a portion of an opaque piece of artwork onto the grid, and determining whether the mapping of the opaque piece of artwork includes a grid cell included in the mapping of the one or more pieces of artwork having a degree of transparency. Based on the determining, the method excludes at least a portion of the opaque artwork from a flattening of at least some of the pieces of artwork.
