Halftone options Halftone options affect the resolution and clarity of your color output. You can select halftone settings for text, graphics, and photographs independently. The two halftone options are Smooth and Detail. ■ The Smooth option provides better results for large, solid-filled print areas. It also enhances photographs by smoothing out fine color gradations. Choose this option when uniform and smooth area fills are top priority. ■ The Detail option is useful for text and graphics that require sharp distinctions among lines or colors, or images that contain a pattern or a high level of detail. Choose this option when sharp edges and details are top priority. Neutral Grays The Neutral Grays setting determines the method used for creating gray colors used in text, graphics, and photographs. Two values are available for the Neutral Grays setting: ■ Black Only generates neutral colors (grays and black) using only black toner. This guarantees neutrals colors without a color cast. ■ 4-Color generates neutral colors (grays and black) by combining all four toner colors. This method produces smoother gradients and transitions to non-neutral colors, and it produces the darkest black. Edge Control The Edge Control setting determines how edges are rendered. Edge control has two components: adaptive halftoning and trapping. Adaptive halftoning increases edge sharpness. Trapping reduces the effect of incorrect color plane registration by overlapping the edges of adjacent objects slightly. Four levels of edge control are available: ■ Maximum is the most aggressive trapping setting. Adaptive halftoning is on for this setting. ■ Normal is the default trapping setting. Trapping is at a medium level and adaptive halftoning is on. ■ 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. ENWW Image-formation troubleshooting 349
