Troubleshooting 187 What is manual color correction? When manual color correction is enabled, the printer employs user‑selected color conversion tables to process objects. However, Color Correction must be set to Manual, or no user‑defined color conversion will be implemented. Manual color correction settings are specific to the type of object being printed (text, graphics, or images), and how the color of the object is specified in the software program (RGB or CMYK combinations). Notes: • Manual color correction is not useful if the software program does not specify colors with RGB or CMYK combinations. It is also not effective in situations in which the software program or the computer operating system controls the adjustment of colors. • When Auto Color Correction is selected, the color conversion tables will generate preferred colors used for the majority of the documents. To manually apply a different color conversion table, do the following: 1 From the Quality menu on the printer control panel, select Color Correction, and then select Manual. 2 From the Quality menu on the printer control panel, select Manual Color, and then select the appropriate color conversion table for the affected object type. Object type Color conversion tables RGB Image RGB Text RGB Graphics • Vivid-Produces brighter, more saturated colors and may be applied to all incoming color formats. • sRGB Display-Produces an output that approximates the colors displayed on a computer monitor. Note: Black toner usage is optimized for printing photographs. • Display‑True Black-Produces an output that approximates the colors displayed on a computer monitor. This uses only black toner to create all levels of neutral gray. • sRGB Vivid-Provides an increased color saturation for the sRGB Display color correction. Note: Black toner usage is optimized for printing business graphics. • Off-No color correction is implemented. CMYK Image CMYK Text CMYK Graphics • US CMYK-Applies color correction to approximate the SWOP (Specifications for Web Offset Publishing) color output. • Euro CMYK-Applies color correction to approximate Euroscale color output. • Vivid CMYK-Increases the color saturation of the US CMYK color correction setting. • Off-No color correction is implemented. How can I match a particular color (such as a corporate logo)? Nine types of Color Samples sets are available from the Quality menu on the printer control panel. These are also available from the Color Samples page of the Embedded Web Server. Selecting any sample set 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.
