To use the Color Swatch feature, you must install the Color 

Swatch Utility. This is supplied on the CD-ROM that was 

supplied with your printer.
The Color Swatch function prints charts which contain a range 

of sample colors. Note that this is not the full range of colors 

that the printer can produce. Listed on each sample color are 

the corresponding RGB (Red, Green, Blue) values. This can be 

used to pick specific colors in applications that allow you to 

choose your own RGB values. Simply click the Color Swatch 

button (1) and choose from the options available.    

You wish to print a logo in a particular shade of red. The steps 

you would follow are:

Print a color swatch, then select the shade of red that best suits 
your needs. 

Take a note of the RGB value for the particular shade that you 
liked.

Using your program’s color picker, enter these same RGB values, 
and change the logo to that color.

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. Here, it is unimportant since your 

primary objective is to print the required color.
