PCS (profile connection space)
A device-independent color space used by a CMM for translating colors from one device's gamut to another. The CMM translates colors from the source color space defined by an ICC device profile to the PCS, and then to the destination color space using a second ICC profile. The PCS is selected by the CMM; it is not visible to users.

page description language (PDL)
A programming language, like those used by printers, that describes the content of a page. Adobe PostScript is the most commonly used PDL for high-end printers.

Perceptual
Also known as the image intent, this rendering intent aims to preserve the visual relationship between colors in a way that is perceived as natural to the human eye, although the color values themselves may change. This intent is most suitable for photographic images.

phosphors
Chemical particles on CRT screens. When energized with the cathode beam, these particles emit light. Different phosphors emit colors with different characteristics.

PostScript
See Adobe PostScript.

pre-mixed inks
See spot color.

primary colors
Colors, usually three, which are combined to produce the full range of other colors within a color model. All non-primary colors are mixtures of two or more primary colors. Red, green, and blue are the primary colors of the additive color model. Cyan, magenta, and yellow are the primary colors of the subtractive color model.

process colors
The subtractive primary colors, cyan, magenta, and yellow (CMY), used in process printing.

process printing
The use of four transparent inks—cyan, magenta, yellow, and black—to print continuous tone color images.

proofer
A device or system used to create tangible output that attempts to simulate final process color presswork. Traditional proofers create output from separation negatives; digital proofers create inkjet prints (e.g., IRIS) or dye-sublimation prints (e.g., Kodak, 3M) directly from digital files.
