Color quality guide Page 5 of 6 What is manual color correction? The color conversion tables applied to each object when using the default Auto Color Correction setting generate preferred color for the majority of documents. Occasionally, you may want to apply a different color table mapping. This customization is accomplished using the Manual Color menu and the Manual Color Correction setting. Manual Color Correction applies to RGB and CMYK color conversion table mappings as defined in the Manual Color menu. You can select any of the different color conversion tables for RGB or CMYK: Color conversion table RGB CMYK Settings • sRGB Display • Display-True Black • sRGB Vivid • Vivid • Off • US CMYK • Euro CMYK • Vivid CMYK • Off Note: The Manual Color Correction setting is not useful if the software application does not specify colors with RGB or CMYK combinations. It is also not effective in situations where the software application or the computer operating system controls the adjustment of colors. How can I match a particular color (such as a corporate logo)? Occasionally, you may have a need for the printed color of a particular object to closely match a specific color. For example, you may need to match the color of a corporate logo. While instances can occur in which the printer cannot exactly reproduce the desired color, you should be able to identify adequate color matches for the majority of cases. The Color Samples menu item can provide useful information in helping solve this particular type of color-matching problem. The nine Color Samples values correspond to color conversion tables in the printer. Selecting any of the Color Samples values generates a multiple-page printout consisting of hundreds of colored boxes. Either a CMYK or RGB combination is located on each box, depending on the table selected. The observed color of each box is obtained by passing the CMYK or RGB combination labeled on the box through the selected color conversion table. You can examine the color samples pages and identify the box whose color is the closest to the desired color. The color combination labeled on the box can then be used for modifying the color of the object in a software application. For instructions, see the software application Help. Manual Color Correction may be necessary to utilize the selected color conversion table for the particular object. Selecting which Color Samples pages to use for a particular color-matching problem depends on the Color Correction setting being used (Auto, Off, or Manual), the type of object being printed (text, graphics, or images), and how the color of the object is specified in the software application (RGB or CMYK combinations). When the printer Color Correction setting is set to Off, the color is based on the print job information; no color conversion is implemented. Note: The Color Samples pages are not useful if the software application does not specify colors with RGB or CMYK combinations. Additionally, certain situations exist where the software application or the computer operating system adjusts the RGB or CMYK combinations specified in the application through color management. The resulting printed color may not be an exact match of the Color Samples pages.
