On the 4, 6 and 8 panel folders and on the tray card what does 4/4 mean?
Printers refer to print jobs based on the number of colors on each side of the paper. Full color printing requires 4 ink colors, Cyan, Magenta, Yellow and Black (called CMYK). A 1/1 job is one color used on both sides of the paper, i.e. black and white. Black is the ink color (white is always the paper color). A 4/4 job is full color on both sides of the paper.
