Print Colour Swatch
This button prints a sample of each colour together with its red
green blue component values. A choice of 4 pages or 12 pages is
available, depending on the colour range you want to see. If you
have problems matching particular screen colours to the printer,
simply print a colour swatch, find the colour you want to print,
and note its RGB component values. Then input these into your
application program to achieve an exact match on the printer.
Halftone Settings
Auto
This selects optimum dithering for most print jobs.
Photo
This is only found under the bitmap tab and prints pixels as
close as possible to the specified density. Any variation
from the data specified is taken in to account when printing
neighbouring pixels. Neighbouring pixels will be printed
lighter or darker to compensate for the variation of the
original pixel. This method produces smooth transitions of
colour within an image.
Graphics/Text
The driver selects fixed size halftone cells which are useful
when printing charts, graphs or other business graphics.
Image Colour Matching
Printer Colour Matching
This colour matching technique uses OKI colour matching
technology to match colours in the document to those
printed. This matching technique is optimized for the
OKIPAGE 8c Plus and replaces the one normally performed
by Windows.
Matching Off
No colour matching is performed. This means that printed
colours will not necessarily match those specified within
the document.
