color correction
A deliberate change of certain colors in the original when it is reproduced. The customer may have requested the modification, or it may be needed because of the colorants that were used to reproduce the image. Inks for process color are not pure colors; each appears as though it is contaminated with the other two colors and has a hue error that requires the compensation in the separation images. The changes can be made electronically, photographically or manually so that the separation films produce the desired result.
color gamut The complete range of hues and strengths of colors that can be achieved with a given set of colorants such as cyan, magenta, yellow and black ink printed on a given paper and given printing press. Although it can represent strength, it usually represents hues.
color management system
A suite of software utility programs capable of making the necessary color transforms from one color space to insure calibrated color
color model
A system for describing every color in a full gamut of color within a color space, such as HLS (hue, saturation and lightness), RGB (red, green and blue) or CIELAB (lightness, redness and blueness).
color negative A color photographic film that was made from an original scene and is used to make a color print or separation. Hues appear reproduced as the complementary values of the original hues
color palette
The range of colors available within a software program or within the computer operating system
color portability
The ability to transfer color images or files from one device to another without significantly changing their appearance
color proof
A visual impression of the expected final reproduction produced on a substrate with inks, pigments or dyes, or on a video screen.
color references A standard set of process inks that were printed to standard densities or strengths on standard paper and are used for color control.
color separation
The process of making a separate electronic or photographic record of the amounts of each process color of cyan, magenta, yellow or black needed to reproduce an original copy. The record may be a photographic film made through red, green and blue separation filters or a computer file. A set of four separations, cyan, magenta, yellow and black, are required to reproduce an original color image, since each of the four process colors must be represented. The separations may be made photographically using traditional methods or digitally using scanners and software. The original copy may be a transparency, reflection photographic print, drawing, painting or printed reproduction.
color sequence
On a printing press or color proof, the order of applying the yellow, magenta, cyan and black inks to the substrate.
color space
A three-dimensional space or model into which the three can be attributes of a color can be represented, plotted or recorded. Although not always called by the names hue, value and chroma, these are the three color attributes represented.
color temperature
The temperature in degrees Kelvin to which a black object would have to be heated to produce a certain color light. 2900K is representative of a tungsten lamp. 5000K is close to the temperature of direct sunlight and is considered the most critical attribute of standard viewing conditions for color evaluation.
comma
,
comprehensive (or comp)
A layout or dummy that is carefully drawn or proofed to size showing all elements in correct size and position. Rendered to present a close approximation of the finished printed piece.
concentricity
Variation between centerline and rotational axis of rotating member
condensed
In typesetting, the compression of font characters width without reducing their height - the opposite of extended
consumable
Material that gets used up in the process of creating printed materials, like film, paper or ink.
contact print A photographic print made with a film positive or negative on presensitized paper, film or printing plates
continuous tone Any photograph or illustration that contains a range of tones or gradation of tones in black and white or color. Must be converted by a halftone screen or digitizing process for printing.
continuous wedge
A narrow strip of film with an orderly progression of grey densities, ranging from zero to maximum density, without definite steps
contone
Jargon for continuous tone
