G-8 Glossary subtractive color model A system in which color is produced by combining colorants such as paint, inks, or dyes on media such as paper, acetate, or transparent film. All printing devices use the subtractive color model. subtractive primaries Cyan, magenta, and yellow colorants used in subtractive color systems for color printing. Combining the subtractive primaries produces darker colors. Black is added to the subtractive primaries to compensate for deficiencies of the toners or inks, and for more efficient black printing. substrate In printing, the material upon which the job is printed. SWOP The abbreviation for Specifications for Web Offset Publications. A standard of specifications for separations, proofs, and color printing on a web offset press (not a sheet fed press). TIFF (Tag Image File Format) A common format for exchanging raster graphics (bitmap) images between application programs. undercolor removal (UCR) A method for improving wet ink trapping and reducing ink costs in process color printing. In shadow areas where all three process colors (C, M, Y) overprint, the amounts of those colors are reduced and replaced by black. vector graphic Graphic illustration created on computers where picture objects are defined mathematically as lines or curves between points. These mathematical definitions are interpreted by an image language such as PostScript. Vector images include artwork created with illustration applications (such as Illustrator or FreeHand) and page layout applications (such as PageMaker). white point The color temperature of any white light source, typically expressed in degrees Kelvin (for example, 6500 K, typical for the white of a monitor). workflow The path a print job follows from creation to destination. A workflow may originate with an RGB scan imported to the client workstation and opened on the desktop in an image processing application, such as Photoshop. After adjustments are made to the scanned image, it is evaluated on a color proofing device for eventual color printing on the same device or on press.
