Colour Adjustments - Oki OKIPAGE 8c Plus Colour Manual

Colour adjustments

Certain images such as bitmaps, sometimes print with a strong
hint of a particular colour. Images that appear fine when viewed
on a monitor may not necessarily print that way due to the reasons
described previously. The colour that appears to dominate the
picture will vary depending on factors such as the scanner (or
other input device) having a bias towards a particular colour, or
the monitor's ability to represent certain colours on-screen. To
compensate for this, the OKIPAGE 8c Plus has a colour adjustment
system that can reduce the amount of any of the process colours
put on the page in relation to the others. If you run Windows on
your computer, the printer drivers supplied with your printer
provide these adjustments. These are outlined in this manual
and explained in more detail in the driver's on-line help. (Click
the Help button in any driver dialogue box.). For other
operating systems or drivers, the printer's Operator Panel
menus provide similar adjustments, detailed in the
OKIPAGE 8c Plus User's Guide.
Colour Guide
This is useful if, for example, you find that all of your graphics
have a tendency to contain too much blue. To compensate for
this, you could reduce the amount of cyan or magenta as it is
these two colours that combine to produce blue. Bear in mind
that other colours containing cyan or magenta will also be
affected. An alternative would be to increase the amount of
yellow. This has the advantage of increasing colour saturation
while balancing the image.
Another method of decreasing strong colours is to increase the
lightness setting in the printer driver. To compensate for this,
the saturation setting must be stepped down accordingly. As a
rule, the saturation should be set down an equal number of steps
to the level that the lightness has been stepped up.
