HP ColorSmart II Note HP ColorSmart II is a set of technologies that enables optimal color output automatically for diverse types of documents. HP ColorSmart II utilizes object tagging and Standard RGB (sRGB) color technologies. Object tagging allows optimal color and halftone settings to be used for different objects on a page (text, graphics, and photos). The printer analyzes objects the page contains and intelligently uses halftone and color settings that provide the best print quality for each object. Object tagging, combined with optimized default settings, produces great color out of the box. In the Windows environment, you will find the HP ColorSmart II Automatic and Manual settings on the Color tab in the printer driver. Color management options Print in grayscale Selecting the Print in Grayscale option in the printer driver allows you to print your document in black and white. This option is useful for previewing preliminary copies of slides and hardcopy output for color documents that will be photocopied or faxed. Automatic color adjustment The Automatic color adjustment feature of HP ColorSmart II (the default setting) optimizes the color and halftones used for each element of a document. Automatic also provides additional color options for application and operating systems that support color management systems. For more information, see your printer driver online Help. Automatic is the default setting and is recommended for printing all color documents. Manual color adjustment The Manual color adjustment feature of HP ColorSmart II allows you to adjust the color and halftone modes for text, graphics, and photographs. To use the Manual color options from the Color tab, select Manual, then select Options. Halftone options Halftone options affect the resolution and clarity of your color output. You can select halftone settings for text, graphics, and photos independently. The two halftone options are Smooth and Detail.
The Smooth option provides better results for large, solid-filled print areas. It also enhances photos by smoothing out fine color gradations.
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. Color map The color map settings in the printer driver tell the printer how to interpret the data sent from a software application into the final colors that the printer will print. The color map settings can be adjusted to Screen match or Vivid.
Screen Match (sRGB - standard red-green-blue) prints colors that are optimized to match RGB monitor colors. Use this setting to more closely match the colors on your screen. A world-wide color standard originally developed by HP and Microsoft, sRGB is a common 246 Troubleshooting C7085-90921
