The proof negatives would be reviewed by the Ohio Geological Survey editor, geologist author, Division Chief, and cartography supervisor before being approved for printing. There are four proof sheets that correspond to one of the CMYK colors (CMYK represents Cyan, Magenta, Yellow, and Black). The top sheet in this image is the black layer.
