Using the Color Swatch feature
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.
An example of using the Color Swatch function:
You wish to print a logo in a particular shade of red. The steps
you would follow are:
1. Print a color swatch, then select the shade of red that best suits
your needs.
2. Take a note of the RGB value for the particular shade that you
liked.
3. 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.
