Document Color Management

Document color management is controlled by three methods.

• Operating system – Windows and MAC
• Application – most applications don’t manage color but some, like Adobe Photoshop, Illustrator and Quark do.
• Printer Driver – through PCL or Postscript It is important to use only one color management method. Applying color management in multiple places can produce unfavorable print output.

These are the software utilities provided with the C9600 driver.

Color Swatch Utility – Allows you to print color samples or swatches which are used with your software program to select and reproduce color accurately.

PDF Print Direct – Ability to print PDF files directly to printer by right clicking on document. (HDD required)

Storage Device Manager – Software to manage hard disk drive.

OKI Profile Assistant – Provides ability to download ICC profiles to HDD. (HDD required)

PS Gamma Adjuster – Feature which can adjust an amount of each of the primary colors (CMYK) that make up a color output to a PostScript printer only. (Windows only)

Color Correct Utility – Provides two methods for adjusting Office Color settings. Modify Hue, Saturation and Gamma. Adjust palette colors used in Microsoft Office applications. (Windows only)

The C9600 Postscript driver provides CMYK simulations for a commercial printing press.

SWOP – North America
Japan Color (obvious)
Euroscale - Europe

The C9600 PCL driver does not support CMYK data. Some applications will provide a choice between RGB or CMYK color. Note there is no CMYK simulation in this driver.

Both the C9600 PCL and Postscript driver provide color management tools within the driver.

• Automatic – applies best choice of Office Color based on the data file received
• Office Color – allows user “Detail” choice for “Color Setting” and “Black Finish”
• Graphic Pro – allows user “Detail” choice for color management, users familiar with ICC profiles
• No Color Matching – turns off printer control, application controls color
• Gray Scale – no color

The C9600 Graphic Pro choice provides more flexibility to control color output. Recommended for users knowledgeable with creating ICC profiles.

OFFICE COLOR - RGB OPTIONS

Office Color provides a collection of several different colors matching presets for RGB data.

These presets each change the color of your print in a slightly different way.

These RGB color matching options are available in all printers drivers.

Monitor (6500K) Auto
The best color match preset will be selected based on the type of document. 6500K - Perceptual will be selected if printing photographs. 6500K - Vivid will be selected if printing graphics and text.

Monitor (6500K) Perceptual
Optimized for printing photographs. Colors are printed with emphasis on saturation.

Monitor (6500K) Vivid
Optimized for printing photographs and for office Graphics. The printer uses even more saturation than the Monitor (6500k) Perceptual setting.

Monitor (9300K)
Colors are printed with emphasis on Lightness. Use this setting if you are having problems achieving the correct color when printing from Microsoft Office
applications.

Digital Camera

Optimized for printing photos taken with a digital camera. Your results will vary depending on the subject and the conditions under which the photograph was taken.

sRGB
The printer will try to reproduce the sRGB color space. This may be useful if color matching from an sRGB input device such as a scanner or digital camera.

CMYK INK SIMULATION
Your printer can be used to simulate the color output of a commercial printing press (SWOP, Euroscale or Japan Color inks).

MORE ACCURATE PRINTER COLOR
If you have created your own profiles with third-party ICC profile creation software, these can be downloaded to the printer and used when printing.

TYPES OF ICC PROFILE SUPPORTED
There are four classes of ICC profile supported by the Graphic Pro color matching system:

RGB Source (RGB Input)
These profiles describe the device that was used to capture RGB data (e.g. scanner or digital camera). The RGB Input Profile may also be your monitor profile if you are trying to match to your screen.

CMYK Simulation (CMYK input)
These profiles describe the CMYK device whose colors you are trying to simulate. Typically this would be another manufacturer’s printer or an offset printing press.
Profiles are already built-in to the printer for commercial printing press inks such as SWOP or Euroscale.

Printer (CMYK Output)
This profile describes the color characteristics of your own printer. The printer already has factory default profiles built-in, but you can replace these profiles with your own if required.

Link Profile
This is a special type of ICC profile that converts directly from CMYK to CMYK. For example, a link profile could convert directly from the CMYK space of another printer to the CMYK space of your printer.

RENDERING INTENTS
When selecting the Printer Output Profile, if you select any other profile apart from [Auto], you can select the Rendering Intent. The rendering intents are essentially a set of rules that determine how colors that fall outside of the printable colors are treated. Select the rendering intent that best suits the document you are
printing.

PERCEPTUAL
This option is recommended for printing photographs. Typically, perceptual rendering desaturates all the colors when printing. This brings unprintable colors into the printer’s range, whilst keeping the elationships between the colors the same.

SATURATION
This option is recommended for printing business graphics if you want vivid colors. This will not necessarily produce accurate color, as the emphasis is on maintaining saturation.

RELATIVE COLORIMETRIC
This option is best for printing solid colors and tints. Use Relative Colorimetric when printing from a drawing program such as Adobe Illustrator, or Macromedia Freehand.

ABSOLUTE COLORIMETRIC
This option is recommended if you are proofing images on your printer that are intended for final output on a printing press. This may result in a visible color cast on your print as it will also try to simulate the paper white of the target device.

PURE BLACK TEXT / GRAPHICS
When your document is printed, often the pure black colors will not be printed using 100% black toner. Instead, these pure black colors are sometimes converted and printed using a mixture of CMYK toner. Using the Pure Black Text / Graphics feature ensures that 100% black text or graphics in your document is printed using pure black toner.

This means that the following colors in your documents will be
printed using only 100% black toner:

RGB Red = 0, Green = 0, Blue = 0

CMYK Cyan = 0%, Yellow = 0%, Magenta = 0%,
Black = 100%

COLOUR MATCH PRECISION
When the printer performs color matching, it must do many calculations to convert between different color formats (RGB, CMYK, etc). These calculations can take time to process. The [Color Match Precision] option allows you to choose between higher quality color matching (more time consuming) or faster but less accurate color matching.
