CMYK

A standard way of representing color for reproduction in a subtractive system such as a printing press. In this color space, colors are represented as combinations of four colorants: cyan, magenta, yellow, and black.


Color space

A model for representing color in terms of measurable values, such as the amount of red, green, and blue in a picture. EfiColor conversions require a source color space and a target color space. The source color space is the origin of a picture's color or the EfiColor Profile for a QuarkXPress color. The target color space is the output device or printing method.


Convert

The process of accurately converting colors from one color space to another. Typically used to accurately render color objects in documents to monitors or printers.


DCS

Desktop Color Separation. A variant of EPS, DCS separates cyan, magenta, yellow, and black data into four files, linked together by a smaller, fifth file. DCS files are used for outputting high-resolution separations to imagesetters, often in conjunction with a page layout application like QuarkXPress.


EPS

An acronym for Encapsulated PostScript, a graphics format used to store high resolution pictures. EPS pictures created on a PC are often called EPSF pictures to distinguish them from EPS files that were created on the Macintosh.


FOCOLTONE

A process color matching system for specifying predictable process colors. All of the 763 colors in the FOCOLTONE color system can be created by printing the specified cyan, magenta, yellow, and black percentages under standard printing conditions.


Gamut

A range of colors. A device gamut is the range of colors that a device, such as a printer, can produce. An image gamut is the range of colors in a particular image.


Gamut Alarm

A tool you can use to check for colors that are out of the gamut of the printer or printing process you plan to use.


Gray Component Replacement

A technique for removing from the color separations some or all of the cyan, magenta, and yellow content that produces gray and replacing them with an appropriate amount of black.


HSB

A color model used most by artists because it resembles the manner in which artists mix colors. Hue describes the color pigment; Saturation is a measure of how much of the color pigment is present; and Brightness is a measure of the amount of black in a color.


LAB

A device-independent color space that plots individual colors in terms of luminance (L) and position relative to two axes (A and B).


Metric Color Tags

A specification that can be attached to a TIFF or EPS picture to define an EfiColor profile for the picture.


OPI

Open Prepress Interface. A specification that integrates high resolution pictures into desktop publishing documents. OPI specifies five files, including a main file that includes a low resolution TIFF for placement in the QuarkXPress document and four separation files that generally reside on a special OPI server.


PANTONE

A color matching system that uses specific PANTONE inks.


PDF

Printer Description File. A file that contains information for printing QuarkXPress documents to non-default printers. Some printer manufacturers included a printer description file with their product.


PostScript

A page description language developed by Adobe Systems, Inc. PostScript is used to describe fonts and graphics as well as the layout of pages.


Process color

1. The four-color process of color reproduction, based on cyan, magenta, yellow, and black inks. 2. A color that is defined as percentages of cyan, magenta, yellow, and black.


Process Separation

The process of separating a color or color picture into primary color components for printing, generally cyan, magenta, yellow, and black. Also used to refer to the four pieces of film that result from the process of separating a color image. Also called color separation.


Profile

A collection of information stored in the EfiColor DB directory that describes a particular device or combination of devices used in the printing process. The EfiColor XTension uses the profile to calculate the appropriate values when reproducing a color.


Rendering style

The process of adjusting the colors in an object to maintain the important aspects of that object on a color output device.


RGB

An additive color system typically used to represent color on video screens. RGB stands for Red, Green, Blue, the basic colors of a video screen.


Separation profile

A profile that is appropriate for separation devices, such as imagesetters. These profiles do not have the name of the imagesetter but are named for the inks and papers used in a printing process involving a press. Separation profiles allow users to control Gray Component Replacement (GCR) values.


Spot color

A color that is printed on its own separation plate when separations are specified. A spot color is printed using a special ink for that color, in contrast to process colors that are printed using combinations of cyan, magenta, yellow, and black.


SWOP

If the profile in the RGB/HSB Colors drop-down list or the CMYK Colors drop-down list is dimmed, the profile is not installed on your computer. Either install the missing profile or change the missing profile to one on your computer. If the Default profiles assigned to the EfiColor Preferences for all new documents is not installed on your computer when you launch QuarkXPress, the EfiColor XTension will not be loaded.


TRUMATCH and FOCOLTONE colors use the SWOP-Coated profile as a default.


PANTONE colors use the LAB profile as a default.


The EfiColor XTension converts colors in RGB and CMYK TIFFs but does not convert colors for EPS and DCS pictures or pictures saved with OPI comments.


If the profile is underlined when you select a picture in the Get Picture dialog box, the picture has been tagged in another application that supports Metric Color Tags. If the profile is underlined but grayed out, the picture has been tagged with a profile not installed on your computer.


Choose Photographic for continuous-tone pictures, such as photographs. Choose Solid Color for pictures with specific color saturation, such as bar charts and logos.


If you choose a picture that is tagged with an EfiColor profile that you do not have in your EfiColor directory, the profile name in the drop-down list is dimmed. You should purchase and install the correct profile.


RGB and HSB colors you create are interpreted based on the default RGB/HSB Colors profile you specify in the EfiColor Preferences dialog box. CMYK colors you create are interpreted based on the default CMYK Colors profile you specify in the EfiColor Preferences dialog box.


TRUMATCH and FOCOLTONE colors use the SWOP-Coated profile as a default.


PANTONE colors use the LAB profile as a default.


If you choose the RGB or HSB color models, the EfiColor XTension provides an outline of the color gamut superimposed over the color wheel. Colors outside the outline are out-of-gamut. If you choose a color model such as PANTONE, TRUMATCH, or FOCOLTONE, the EfiColor XTension displays slash marks through color swatches that will not be printed correctly.


To help you remember whether a color you create is a spot or process color, add "spot" to the names of spot colors and "process" to the names of process colors.


To help you remember the source profile set in the EfiColor Preferences dialog box, enter an abbreviation of the RGB/HSB or CMYK source profile after the color name.


Be sure the printing device you choose in the Use PDF For drop-down list and EfiColor Profile drop-down list is also selected in the Printer area.


If you receive a document for text proofing only, you will probably not want to assign different profiles for the missing ones. You can print without replacing profiles and it will not alter the profiles assigned to pictures and colors.


When you replace profiles assigned to RGB/HSB Colors or CMYK Colors, you also change the default profiles for RGB/HSB Colors and CMYK Colors in the EfiColor Preferences dialog box.
