Color Print Matching
The install utility provides a color matching profile for your printer. In
general, using these Color Matching settings will provide reasonable
default settings that produce good results for most documents.
Many applications have theirown color settings and these may override
the settings in the printer driver. Please refer to the documentation for
your software application for details on how that particular program’s
color management functions.
Factors That Affect the Appearance of
Printed Documents
Ifyou wish to manually adjust the color settings in your printer driver,
please be aware that color reproduction is a complex topic, and
there are many factors to take into consideration. Some of the most
important factors are listed below.
Range of Colors: Monitors Versus Printers
•Neither a printer nor a monitor is capable of reproducing the full
range of colors visible to the human eye. Each device is restricted to
a certain range of colors. In addition to this, a printer cannot
reproduce all of the colors displayed on a monitor, and vice versa.
•Both devices use very different technologies to represent color. A
monitor uses Red, Green and Blue (RGB) phosphors (or LCDs), a
printer uses Cyan, Magenta, Yellow and Black (CMYK) toner or ink.
•A monitor can display very vivid colors such as intense reds and
blues and these cannot be easily produced on any printer using
toner or ink. Similarly, there are certain colors, (some yellows for
example), that can be printed, but cannot be displayed accurately on
a monitor. This disparity between monitors and printers is often the
main reason that printed colors do not match the colors displayed on
screen.
Viewing conditions
A printed document can look very different under different lighting
conditions. For example, the colors may look different when viewed

Color Print Matching: • 7
standing next to a sunlit window, compared to how they look under
standard office fluorescent lighting.
Printer driver color settings
The driver settings for Manual color can change the appearance of
a printed document. There are several options available to help
match the printed colors with those displayed on screen. These
options are explained in subsequent sections.
To access the color matching options in the driver discussed below:
1. Access the printer settings page via the Print dialog from any
application (usually accessed via File →Print).
2. Click on the General drop down menu and select Color Option.
Monitor settings
The brightness and contrast controls on your monitor can change
how your document looks on-screen. Additionally, your monitor’s
color temperature influences how “warm” or “cool” the colors look.
NOTE
Several of the Color Matching options make reference
to your monitor’s Color Temperature. Many modern
monitors allow the color temperature to be adjusted
using the monitor’s control panel.

Color Print Matching: • 8
There are several settings found on a typical monitor:
• 5000k*
Warmest; yellowish lighting, typically used in graphics arts
environments.
• 6500k
Cooler; approximates daylight conditions.
• 9300k
Cool; the default setting for many monitors and television sets.
*k = degrees Kelvin, a measurement of temperature
How Your Software Application Displays Color
Some graphics applications such as CorelDRAW®or Adobe®
Photoshop®may display color differently from "office" applications
such as Microsoft®Word. Please see your application’s on-line help
or user manual for more information.
Paper Type
The type of paper used can also significantly affect the printed color.
For example, a printout on recycled paper can look duller than one
on specially formulated glossy paper.
Choosing a Color Matching Method
There is no one correct way to achieve a good match between the
document displayed on your monitor and its printed equivalent.
There are many factors involved in achieving accurate and
reproducible color.

Color Print Matching: • 9
The following guidelines may help in achieving good color output
from your printer. There are several suggested methods, depending
on the type of document you are printing.
RGB or CMYK?
The guidelines for choosing a color matching method make
distinctions between Red, Green, Blue (RGB) and Cyan, Magenta,
Yellow, Black (CMYK).
Generally, most documents you print will be in RGB format. This is
the most common, and if you do not know your document’s color
mode, assume that it is RGB.
Typically CMYK documents are only supported in professional
Desktop Publishing and Graphics applications.
Matching Photographic Images
RGB only
Oki Color Matching (found in the printer driver under Color Control)
is a generally a good choice. Select a matching method appropriate
to your monitor.
NOTE
These suggestions are for guidance only. Your results
may vary depending on the application from which you
are printing. Some applications will override any color
matching settings in the printer driver without warning.

Color Print Matching: • 10
RGB or CMYK
If you are printing photographic images from a graphics application
such as Adobe Photoshop, you may be able to use Soft-Proofing to
simulate the printed image on your monitor. To do this, you can use
the ICC-Profiles provided by Oki, and then print using the ICC
profiles as the Print Space (or Output space).
Matching Specific Colors
(For instance, a company logo.)
RGB only
•Oki Color Matching, and the sRGB setting.
•PostScript Color Matching using the Absolute Colorimetric option.
•Use the Color Swatch Utility to print out a chart of RGB swatches
and enter your desired RGB values in your application's color picker.
RGB or CMYK
•If you are printing from a graphics application such as Adobe
Photoshop, you may be able to use Soft-Proofing to simulate the
printed image on your monitor. To do this, you can use the ICC
Profiles provided with your printer, and then print using the ICC
profiles as the Print Space (or Output space).
•Alternatively, use PostScript Color Matching with the Absolute
Colorimetric setting.
Printing Vivid Colors
RGB only
•Use Oki Color Matching, with either the Monitor 6500k Vivid, sRGB
or Digital Camera settings.
RGB or CMYK
•Use PostScript Color Matching with the Saturation option.

Operation_____________________
This section will only detail options as they apply to the LaserWriter®
8 driver. Refer to manufacturer’s guidelines regarding other driver
operations.
Oki Driver Options
This section references only the OKI-supplied driver selections,
Color Option and Job Option, as well as the plug-ins Job
Accounting and Job Type - if available.
Color Option
To access Color Option
1. Select your desired printer from an application using File →Print.
2. Open the drop-down menu directly underneath the printer and
select Color Option.

Macintosh OS 9x: Operation • 13
Color Control
Color Control allows you to determine the scheme in which the
printer will display colors.
OKI Color Matching
This is OKI’s proprietary color matching system and affects RGB
data only. This is the default setting and provides the fastest, best
color matching for your printer.
Postscript Color Matching
This uses PostScript Color Rendering Dictionaries built-in to the
printer, and affects both RGB and CMYK data.
No Color Matching
No color correction occurs when selected. This option is beneficial
when other matching regimens are used, specifically if you select a
Color Simulation option.
Print In Grayscale
No color will print. The printer will interpret all colors as a variation of
grays.
Color Setting
This option allows you to select your color settings as they appear
on your monitor.
Monitor(6500k) Auto
The default setting that selects the best options for your printer. This
selection works best for office situations.

Macintosh OS 9x: Operation • 14
Monitor (6500k) Perceptual
Optimized for printing photographs when using a monitor with a color
temperature of 6500K, This is best for printing photographic images.
Monitor (6500k) Vivid
Optimized for printing bright colors when using a monitor with a color
temperature of 6500K. Ideal for office graphics and text. Vivid or
Digital Camera settings produce brightest colors.
Monitor (9300k)
Optimized for printing photographs when using a monitor with a color
temperature of 6500K.
Digital Camera
Optimized for printing photographs taken with a digital camera. This
tends to produce prints with lighter and brighter colors. For some
photographs,othersettingsmay bebetter dependingon thesubjects
and the conditions under which they were taken. Vivid or Digital
Camera settings produce brightest colors.
sRGB
Optimized for matching specific colors, such as a company logo
color. This option attempts to simulate RGB color. The colors within
the printer's color gamut are printed without any modification, and
only colors that fall outside the printable colors are modified.
Rendering
When a document is printed, a conversion takes place from the
document's color space to the printer color space. The rendering
intents are essentially a set of rules that determine how this color
conversion takes place.
Auto
The default. Auto uses the optimum settings for a general office
environment.

Macintosh OS 9x: Operation • 15
Perceptual
Best choice for printing photographs. Compresses the source gamut
into the printer's gamut while maintaining the overall appearance of
an image. This may change the overall appearance of an image as
all the colors are shifted together.
Saturation
Best choice for printing bright & saturated colors if you don't
necessarily care how accurate the colors are. This makes it the
recommended choice for graphs, charts, diagrams etc. Maps fully
saturated colors in the source gamut to fully saturated colors in the
printer's gamut.
Relative Colorimetric
Good for proofing CMYK color images on a desktop printer. Much
like Absolute Colorimetric, except that it scales the source white to
the (usually) paper white; i.e. unlike Absolute Colorimetric, this
attempts to take the paper white into account.
Absolute Colorimetric
Best for printing solid colors and tints, such as company logos etc.
Matches colors common to both devices exactly, and clips the out of
gamut colors to their nearest printed equivalent. Tries to print white
as it appears on screen. The white of amonitor is often very different
from paper white, so this may result in color casts, especially in the
lighter areas of an image.
Color Simulation
This affects CMYK output only and is usually used in offset printer
environments only.
This option simulates what the output will look on a printing press
using the ink types SWOP, Euroscale or Japan. If using CMYK Ink
Simulation, it is recommended that you switch off all other Printer
Color Matching by selecting the No Color Matching option under the
Color Match option in the printer driver.

Macintosh OS 9x: Operation • 16
Black Finish
This setting determines Black Toner usage only.
Auto
This option is best for an office environment, with the printer
determining which style is better.
Glossy
This option uses more CMYK and less Black while producing a
shinier black.
Matte
This option uses more Black and less CMYK while producinga flatter
black.
Separations
This option affects output only, allowing you to print all colors as
separate plates.
NOTE
You must select a non-generic PostScript Printer
Description (PPD) file for a printer that supports color
separations.
