C7350/7550 User’s Guide: Windows 2000 Operation • 236 Color Matching Color Matching Options Print Color Swatch Utility For use with applications which allow you to set your own RGB values for colors. The Color Swatch utility prints out charts of sample colors. Listed below each color are the corresponding RGB (Red, Green, Blue) values to use in your application to match that printed color. An example of using the Print Color Swatch function: You wish to print a logo in a particular shade of red. The steps you would follow are: 1.Click Start → Settings → Printers. 2.Right click the printer name. Click Printing Preferences. 3.Click the Color tab. 4.Click the Color Swatch button to print the color swatch samples. 5.Select the shade of red that best suits your needs. Make a note of the RGB value below that particular shade. 6.Use your program’s color picker to enter the same RGB values (from step 5). Change the logo to that color. NOTE The RGB color displayed on your monitor may not necessarily match what was printed on the color swatch. If this is the case, it is probably due to the difference between how your monitor and printer reproduce color. Downloaded From ManualsPrinter.com Manuals
