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, 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.

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 colo r. 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 disp arity between mo nitors and printers is of ten the main reason that printed colors do not match the colors displayed on screen.

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 cha nge 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.

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.

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.

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 applications such as Microsoft

Photoshop® may display color differently from “office”

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.

Choosing a Color Matching Method

There is no one way to achieve a good match between the document displayed on your monitor and its printed equivalent. There are man y 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.

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 mat ching settings in the printer driver without warning.

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 pr ofe ss ion al Desktop Publishing and Graphics applications.

Matching Photographic Images

RGB Only

The standard Color Matching (found in the printer driver und er 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 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).

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 Ado be

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 Digit al

Camera settings.

RGB or CMYK

• Use PostScript Color Matching with the Saturation option.

Color Option

Mac9.1_OKIColorOption.jpg

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.

ColorOptionSelecting_crop.jpg

Color Control

Color Control allows you to determine the scheme in which the printer will display colors.

Mac9.1_ColorControl.jpg

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. Pos tScript 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 matching regimens 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.

Color Setting

This option allows you to select your color settings as they appear on your monitor.

ColorSettingDialog.jpg

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 on the subjects and the conditions under which they were taken. Vi vid or Digital Camera settings produce brightest colors.

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.

RenderingDialog.jpg

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 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 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.

ColorSimulation.jpg

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.

BlackFinish.jpg

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 producing a flatter black.

Separations

This option affects output only, allowing you to print all four colors as separate plates.

Separations.jpg

Black Overprint

This option prevents registration errors and only works for 100% black text.

Click the checkbox to enable the option.
