What are the color options?

Color options for pre-press printing are divided into three categories:

Full Color Front/Full Color Back, or Four over Four (4/4): Four-color print job with color on both sides of the paper.

Full Color Front/Grayscale Back, or Four over One (4/1): Full-color print job on the front, and black and white (grayscale) on the back.

Full Color Front/Blank Back, or Four over Zero (4/0): Four-color print job on the front, and no printing on the back.
