Color separations are the four-color negatives or positives which are the result of changing full color artwork into the four process colors (yellow, magenta, cyan, and black) by the use of filters. Color separation is done for offset printing jobs so that each color layer can be printed separately - one layer on top of the next layer - to give the final printed piece a consistent, full color look.

Computer-to-Plate or CTP describes a system in which the use of desktop publishing software, electronic prepress workstations, and platesetters allows the imaging of metal plates for any format of press without the use of film, stripping or traditional platemaking. This process results in lower costs while shortening the amount of time needed to get a job on the press.

| top |
Duotone is a halftone that prints in two colors to create greater visual interest or more subtle detail and gray tones.
| top |
Duplexing is the ability of a press or digital copier to print on both sides of a sheet without having to manually turn the sheet over.
| top |
