Definitions for "Progressive proof"
A series of color proofs showing the individual, variously combined, and collectively combined colors used in four color process printing. Each color is shown separately in combination with each other color, and in combination with every possible color combination - finally concluding with a four color simulation of the printed piece. These proofs are used to determine the density of each color and each color's effect on the other colors, especially in the order they are printed on the press.
Color proof that show the reproduction of each color plate separately and in combination with each other. Each color is on a separate piece of acetate, then combined together in layers.
Press proof showing each color of a job separately or several colors in combination.
