Tips for Printing in Color
Printing Photographic images
Use the Monitor (6500k) Perceptual
setting. If the colors look too dull, try
the Monitor (6500k) Vivid or Digital
Camera settings.
Printing from Microsoft Office
Applications
Use the Monitor (9300k) setting. This
may help if you are having problems
with specific colors from applications
such as Microsoft Excel or Microsoft
Powerpoint.
Printing Specific Colors (e g.
company Logo)
There are 2 utilities on your printer
driver CD-ROM that can help match
specific colors:
- Color Swatch Utility
- Color Correct Utility
Adjusting the Brightness or
Intensity of a Print
If the print is too light/dark, use the
Brightness control to adjust it.
If the colors are too intense/not
intense enough, use the Saturation
control.
