Values: Auto* Vivid Off CMYK Black and White Display 2-Color Draft Applies the optimum color settings for typical business applications, where jobs contain a mixture of text, graphics, and images. Prints bright, well-saturated colors. Prints without any color correction, thereby allowing computer-based color management systems such as Windows ICM or Apple ColorSync to define the printed color. Lets applications that do their own color correction for CMYK colors (such as CorelDraw, Adobe PhotoShop, or Adobe Illustrator) print without interference from the printer color corrections. Useful for pre-press simulations. Note: CMYK is not supported in PCL. Prints images in a monochrome grayscale. Useful if you want to preserve color supplies or if you need to make black-and-white photocopies of a color image. Prints colors that approximate those that appear on a standard computer monitor. Prints using only cyan and black, thereby providing limited color output with reduced consumption of color supplies and a faster print speed. Note: 2-Color Draft is not supported in PCL. Note: Due to the differences between additive and subtractive colors, certain colors that appear on your monitor are impossible to duplicate on your printer. See also: Color correction 208
