● Light sets trapping at a minimal level, and adaptive halftoning is on. ● Off turns off both trapping and adaptive halftoning. RGB color Two values are available for the RGB Color setting: ● Default instructs the printer to interpret RGB color as sRGB. sRGB is the accepted standard of Microsoft and the World Wide Web Organization (www). ● Vivid instructs the printer to increase the color saturation in the midtones. Less colorful objects are rendered more colorfully. This value is recommended for the printing business graphics. ● Device instructs the printer to print RGB data in raw device mode. To render photographs properly with this selection, you must manage image color in the program or operating system. Adjusting color balance This MFP features automatic color calibration to provide high-quality color output. In situations that require critical color control, you can manually adjust the density balance of the four toner colors. The available range for each color is from -5 to +5. The default value is 0. CAUTION: This procedure should only be performed by your network administrator. Performing this procedure changes the color balance of the MFP by altering halftones, and affects all print jobs. 1. Scroll to and touch Administration. 2. Scroll to and touch Print Quality. 3. Scroll to and touch Adjust Color. 4. Touch Highlights Midtones, or Shadows. 5. Scroll to and touch the correct density setting. 6. After setting the density for each color, touch Exit. Color selection process The user selects the color in the program, but the operating system might convert or modify some characteristics of the color before sending the information to the printer driver. The printer driver might also modify color characteristics depending upon the selected output mode. Any color characteristics that the printer driver or programs do not address are set to the printer default. The default color might not match the color the user selected. Matching colors PANTONE color matching PANTONE has multiple color-matching systems. PANTONE Matching System is very popular and uses solid inks to generate a wide range of color hues and tints. See http://www.hp.com for details about how to use PANTONE Matching System with this printer. 610 Chapter 6 Problem solving ENWW
