Color correction descriptions

Turning off all color corrections

If you do not want to use any TekColor color corrections, you can specify no corrections from a supported driver, with a PostScript utility Þle, from the printerÕs front panel or through PhaserLink software. Select None when you are doing the following:

■Using applications that do their own color adjusting

■Using ColorSync on a Macintosh or host color correction in Windows 95

■Printing PANTONE Colors

Printing the brightest colors and a truer blue

The Vivid Color option is the best choice for the brightest, most vibrant prints. This option also 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 donÕt need to match the screenÕs 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 speciÞed 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 donÕt perform their own color corrections. This selection is best for applications that deÞne colors as RGB (red, green, blue), HLS (hue, lightness, saturation), or HSB (hue, saturation, brightness).
