For prints containing only graphics, use the Vivid Color option.
For engineering and scientific imaging applications, try printing with the Simulate Display or Vivid Color option.
For graphic arts purposes, there are three printing press standards to choose from: SWOP Press (Specifications for Web Offset Publications), Commercial Press and Euroscale Press.
TekColor color corrections are performed in the printer. To use ColorSync color matching on a Macintosh, or to use host color correction in Windows 95, refer to the topics on the printer's CD-ROM or the Tektronix World Wide Web site.
Note: TekColor color corrections do not affect colors specified in the PostScript Level 2 international color standard CIE XYZ developed by the Commission Internationale de l'Eclairage (International Commission on Illumination).
Deciding which color correction to use Color printers and computer display screens produce color differently. Printers use the subtractive primaries CMYK (cyan, magenta, yellow, and black), and produce color when light is reflected off the paper. Computers use the additive primaries RGB (red, green, blue) with a light-emitting CRT screen. The printer and the computer screen each have a different range of possible colors they can produce, with some overlap between them.
Software application packages specify color in different ways, for example as CMYK or RGB, or they may give you a choice. Get to know your applications so you can work more efficiently.
The TekColor color correction options are available for a finer degree of control over color. Since no single color correction option can address all uses, refer to the following table for the description that best fits your printing situation, and try the suggested color correction.
Color correction descriptions Turning off all color corrections If you do not want to use any TekColor color corrections, you can specify None from a supported driver, with utility files, or from the printer's front panel. Select None when you are doing the following:

Printing printer-specific PANTONE Colors
Note: For more information on PANTONE Colors, refer to the topics on the Tektronix Color Printer World Wide Web site: http://www.tektronix.xerox.com/support/
Printing the brightest colors and a truer blue The Vivid Color option makes printed blue appear less purple by reducing the amount of magenta used to print blue colors. Other colors in the cyan-blue-purple- magenta range in the image are also adjusted to compensate for the adjusted blue. Colors in the red-orange-yellow-green range are not affected. This selection is good for making presentation graphics, such as overhead transparencies, and for bright-looking colors that don't need to match the screen's colors or printing press colors.
Vivid Color adjusts CMYK colors using a method that adds black to other components. This option prints more saturated (darker) colors and may be useful for printing overhead transparencies for presentations from some applications, such as CorelDRAW!. Use this option if you have specified a color in the CMYK system, and the color has a black component, and the color appears lighter than you expected when printed.
Simulating display screen colors The Simulate Display option makes printed colors approximate the colors on a standard display screen. This selection should improve the screen-to-printer color accuracy for most applications that don't perform their own color corrections. This selection is best for applications that define colors as RGB (red, green, blue), HLS (hue, lightness, saturation), or HSB (hue, saturation, brightness).
Closely match printing press colors There are three printing press color correction options. Each press option conforms to a different printing standard. Use a press option if you are previewing work for a four-color job to be printed on a printing press. These options simulate a four-color commercial printing press, not solid spot colors, such as PANTONE PMS Colors.
Note: If you are selectingprinter-specific PANTONE Colors in your application, use the None option; see Turning off all color corrections. Also, use the None option with other color management systems, such as EfiColor.
These are specifications for color separation films and color proofing that are used to ensure the consistency of printed colors between different publications. This option is typically used in the U.S., and is characterized to match Imation Matchprint proofs.
Used for high-volume, web press printing.
Used for high-quality, sheet-fed printing.
Using the printer's current color defaults The Use Printer Setting option is available only in the supported drivers. This option sends no color correction information to the printer. It uses the current default in the printer to process colors for printing. The factory default color correction is Automatic. The printer's default can be one of the following:
One of the color correction utility files sent to the printer.
Raw CMYK Colors (RAWCMYK.PS): Converts all colors (CMYK, RGB, grays) to CMYK colors. Use this file if your application specifies colors as CMYK (cyan, magenta, yellow, and black). This file lets you control the CMYK output of the printer's colors without using any TekColor color corrections. Use this file with the Fast Color print-quality mode to increase throughput.
Raw RGB Colors (RAWRGB.PS): Converts all colors (CMY, CMYK, grays) to RGB colors. Use this file if your application specifies colors as RGB (red, green, and blue). This file lets you control the CMY output of the printer's colors without using any TekColor color corrections. Use this file with the Standard print-quality mode to increase throughput.
Note: Refer to the on-line documentation on the printer's CD-ROM for instructions on installing and using the utility files.
Application color corrections Some applications perform color corrections to improve screen-to-printer color matching. The TekColor color correction options in the supported drivers adjust colors in the printer after the application has performed its color corrections.
If you select a TekColor color correction option in a driver other than None, the selection may override some application features.
If you try one of the TekColor color correction options in a supported driver and the printed results are not what you expected, then select the None option and try reprinting your image.
Select the None TekColor color correction option in a supported driver if you are using ColorSync color matching on a Macintosh or host color correction in Windows 95 (refer to the CD-ROM or World Wide Web ColorSync topics).
