Macintosh OS 9.x
Operation
This section explains how to change the printer’s operation for
specific print jobs directly from within an application.
Most applications allow the printer properties to be accessed from
within the document print dialog.
This section will only detail options as they apply to the LaserWriter®
8 driver. Refer to manufacturer’s guidelines regarding other driver
operations, for example the AdobePS™ driver.

Color Print Matching
The install utility provides a color matching profile for your printer, as
well as Color Option utility in the print driver. In general, using the
Auto settings will provide reasonable default settings that produce
good results for most documents.
Many applications have their own 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.
If you wish to manually adjust the color settings in your printer driver,
pleasebe aware that color reproduction isa complex topic, and there
are many factors to take into consideration. Some of the most
important factors are listed below.
Differences between the Range of Colors a Monitor or
Printer Can Reproduce
•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.

9
Viewing Conditions
A document can look very different under various lighting conditions.
For example, the colors may look different when viewed 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
document. There are several options available to help match the
printed colors with those displayed on screen. These options are
explained in subsequent sections of this User Manual.
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 the General drop down menu and select Color Option.

10
Monitor Settings
The brightness and contrast controls on your monitor can change
how your document looks on-screen. Additionally, your monitor color
temperature influences how “warm” or “cool” the colors look.
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 Macromedia Freehand®or
Adobe®Photoshop® may display color differently from “office”
applications such as Microsoft®Word. Please see your application’s
online 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.
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.

11
Choosing a Color Matching Method
There is no one way to achieve a good match between the document
displayed onyour monitor and itsprinted equivalent. There are many
factors involved in achieving accurate and reproducible color.
However, 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 makes
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
The standard Color Matching (found in the printer driver under
Color Matching) is a generally a good choice. Select a matching
method appropriate to your monitor.
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 theprinted image on your monitor. To do
this, you can use the ICC-Profiles provided, and then print using
the ICC profiles as the Print Space (or Output space).
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.

12
Matching Specific Colors
(e.g., a Company logo)
RGB Only
•Standard 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, 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 Color Matching, with the Monitor 6500k Vivid, sRGB or Digital
Camera settings.
RGB or CMYK
•Use PostScript Color Matching with the Saturation option.

13
Color Option
1. Open your printer driver (by choosing File →Print from an
application) and select your printer.
2. Open the drop-down menu directly underneath the printer and
select Color Option.

14
Color Control
Color Control allows you to determine the scheme in which the
printer will display colors.
Select from:
a. OKI Color Matching
This is OKI’s proprietary color matching system. It affects RGB
data only. This is the default setting. This option provides the
fastest, best color matching for your printer.
b. PostScript Color Matching
This uses PostScript Color Rendering Dictionaries built into the
printer. It affects both RGB and CMYK data.
c. PANTONE®
Uses PANTONE color definitions built into the printer.
d. No Color Matching
No color correction occurs when selected. This option is
beneficial when other matchingregimens are used, specifically
if you select a Color Simulation option.
e. Print in Grayscale
No color will print. The printer will interpret all colors as a
variation of grays.

15
Color Setting
This option allows you to select your color settings as they appear on
your monitor.
Select the method you wish to use:
Monitor(6500k) Auto
The default setting that selects the best options for your printer.
This selection works best for office situations.
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 9300K.
Digital Camera
Optimized for printing photographs taken with a digital camera.
This tends to produce prints with lighter and brighter colors. For
some photographs, other settings may be better depending onthe
subjects and the conditions underwhich they were taken. Vivid or
Digital Camera settings produce brightest colors.

16
sRGB
This option attempts to simulate RGB color.
Optimized for matching specific colors, such as a company logo
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.
Select the desired option:
Auto
The best default. This selects the optimal settings for a general
office environment.
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 and 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
saturatedcolorsin the sourcegamutto fullysaturatedcolorsinthe
printer's gamut.
Relative Colorimetric
Good for proofing CMYK color images on a desktop printer. Much
likeAbsolute Colorimetric, except that it scales the source white to
RenderingDialog.jpg

17
the (usually) paper white; i.e. unlike Absolute Colorimetric, this
attempts to take the paper white into account.
Absolute Colorimetric
Bestforprinting solid colorsand tints,suchas 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 a monitor is often
very different from paper white, so this may result in color casts,
especially in the lighter areas of an image.
Color Simulation
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 No Color Matching under the Color
Match option in the printer driver.
Select the option desired.
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.
ColorSimulation.jpg
BlackFinish.jpg

18
Matte
This option uses more Black and less CMYK while producing a
flatter black.
Separations
This option affects output only, allowing you to print all four colors as
separate plates.
Black Overprint
This option prevents registration errors and only works for 100%
black text.
Click the checkbox to enable the option.
Printer Halftone
This option prevents the halftone of a high-end graphics application
from printing.
Click the checkbox to enable the option.
Custom Gamma Adjustment
Not available.
