● Dry Time: Move the slider to the right to increase the amount of time that the printer takes to dry a printed page. Increasing the drying time works best for jobs printed on plain paper. ● Saturation: Move the slider to the right to increase the amount of black or color applied. Increasing the saturation works best for jobs printed on brochure or photo paper. ● Black Ink Spread: Move the slider to the left to limit the spread of black onto adjacent areas of color on the printed page. Decreasing the spread works best for jobs printed on plain paper. NOTE: Changing color settings manually can affect output. HP recommends that only color graphics experts change these settings. 6. Click OK to save your adjustments and close the window, or click Reset to return the settings to the factory defaults (Windows). Match colors to your computer screen For most users, the best method for matching colors is to print sRGB colors. The process of matching printer output color to your computer screen is complex, because printers and computer monitors use different methods of producing color. Monitors display colors by using light pixels that use an RGB (red, green, blue) color process, but printers print colors by using a CMYK (cyan, magenta, yellow, and black) process. Many factors can influence your ability to match printed colors to those on your monitor: ● Print media ● Printing process (cartridge, press, or laser technology, for example) ● Overhead lighting ● Personal differences in perception of color ● Software programs ● Printer drivers ● Computer operating systems ● Monitors ● Video cards and drivers ● Operating environment (humidity, for example) Control access to color printing HP's suite of color access control tools allows you to enable or disable color by individual users or groups and applications.
