•Deﬁne the source of incoming RGB color data for better screen matching and provide for better color conversion of RGB data with no source information.

•Deﬁne whether RGB data is converted into the full gamut of the printer or is ﬁrst converted into the gamut of another device, such as a press standard. This feature is helpful for making one device behave like another. It is also useful for evaluating the appearance of the RGB ﬁle under different printing conditions without having to reprocess the RGB data each time.

ColorWise color management (ColorWise)

offers an open color architecture, allowing users to customize the EX7750 to meet new printing needs as they arise. ColorWise supports

ICC proﬁles

, which are industry standard color proﬁles that describe the color behavior of a device. Downloading ICC proﬁles to the EX7750 enables the EX7750 to simulate a custom press (or another printer), as well as accurately print colors from a particular monitor or a scanner. In addition, you can create customized ICC proﬁles for the printer.

ColorWise also allows you to use any

Status T

densitometer by importing data in a standard ﬁle format (see Appendix B). In this case, it is important to note that the quality of the instrument used determines the quality of the

Managing color on the EX7750

To modify EX7750 printing behavior, do any of the following:

•Select ColorWise options for an individual print job using menus that appear in the

printer driver.

•Select most ColorWise options as server defaults from the Color Setup application

in ColorWise Pro Tools (see page 3-35). Defaults can also be set from EX7750 Setup, as described in the subsequent print jobs unless you override them.

For users who are familiar with PostScript 3 color, RGB Source Proﬁle affects all CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to the EX7750 in CIEBasedDEFG format, for example, by choosing PostScript Color Management in Adobe Photoshop, the EX7750 Rendering Style selection—which normally affects only RGB data—will also affect this CMYK data.

1-3 Managing color on the EX7750

You can specify settings for the following options by selecting print options when you send a job to the EX7750. Some can also be set as defaults by the administrator during EX7750 Setup or using ColorWise Pro Tools. Settings speciﬁed using print options override the defaults.

Rendering Style

The Rendering Style option speciﬁes a CRD for color conversions. To control the appearance of images, such as prints from ofﬁce applications or RGB photographs from Photoshop, select the appropriate Rendering Style. The EX7750 allows you to select from the four rendering styles currently found in industry standard ICC proﬁles.

EX7750 rendering style Best used for

Photographic—Typically results

in less saturated output than presentation rendering when printing out-of-gamut colors. It preserves tonal relationships in images.

Presentation

saturated colors but does not match printed colors precisely to displayed colors. In-gamut colors such as ﬂesh tones are rendered well; similar to the Photographic rendering style.

Relative Colorimetric—Provides

white-point transformation between the source and destination white points. For example, the bluish gray color of a monitor will map to neutral gray. You may prefer this style to avoid visible borders when not printing full-bleed.

—Creates

Photographs, including scans and images from stock photography CDs and digital camera images.

Artwork and graphs in presentations. In many cases, it can be used for mixed pages that contain both presentation graphics and photographs.

Advanced use when color matching is important, but you prefer white colors in the document to print as paper white. It may also be used with PostScript color management to affect CMYK data for simulation purposes.

NOTE: The rendering styles associated with the PCL driver do not match those

associated with the PostScript driver.

Pure Black Text/Graphics

The Pure Black Text/Graphics option affects the printout for black text and vector

graphics on a page. Under most circumstances, leave this option set to On. When

Pure Black Text/Graphics is on, black colors generated by applications (for example, RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the maximum amount of black toner allowed by the calibration curve. This means the black text and line art will not exhibit halftone artifacts (as long as the printer is calibrated correctly) and will not be misregistered, since there is only one toner used. In addition, this setting eliminates blasting.

For some jobs, it is preferable to clear this option, for example, if the page includes

gradient ﬁlls that use black. The following table describes the behavior of the Pure

Black Text/Graphics option with black data deﬁned in different color spaces.

NOTE: Use the Pure Black Text/Graphics option only when printing composites, not

when printing separations.

1-8 EX7750 Color Management

NOTE: PostScript applications (such as QuarkXPress) may convert elements deﬁned as

RGB = 0, 0, 0 to four-color CMYK black before sending the job to the EX7750. These elements are not affected by the Pure Black Text/Graphics option. For details, see the

Fiery Color Reference. Also, black text and line art deﬁned as RGB = 0, 0, 0 in ofﬁce

applications (such as Microsoft Word) are converted to single-color black (CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows 2000/XP. To print this single-color black at the maximum toner density of the printer, set the Pure Black Text/Graphics option to On.

NOTE: This feature is not available with the PCL driver.

Black Overprint

The Black Overprint option allows you to specify whether or not black text or text/graphics, deﬁned as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%, overprints colored backgrounds.

Text—Black text overprints colored backgrounds, eliminating white gaps and

•

reducing halo effects or misregistration of colors.

• Text & Graphics—Black text and graphics overprint colored backgrounds,

eliminating white gaps and reducing halo effects or misregistration of colors.

• Off—Black text or text/graphics knocks out colored backgrounds.

NOTE: PostScript applications may perform their own black overprint conversions

before sending the print job to the EX7750.

1-9 Managing color on the EX7750

One example of how you might use this setting is with a page that contains black text on a light blue background. The background blue color is CMYK = 40%, 30%, 0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%.

•With Black Overprint set to Text or Text/Graphics, the ﬁnal text or text/graphic

portions of the page are overprinted, or combined with the underlying colors. Black colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%, 0%, 0%, 100%) are printed using the maximum amount of black toner allowed by the calibration curve. This means that black text and line art will not exhibit halftone artifacts (as long as the printer is calibrated correctly). There is no transition in the cyan and magenta toners, and the quality of the output is improved since it will not show artifacts near the edges of the text or text/graphics. The option also works with text deﬁned in the RGB color space, that is RGB = 0, 0, 0.

•With Black Overprint Off, the border of the text or text/graphics is on an edge that

has cyan and magenta toners on one side (outside the text) and black toner on the other side (inside the text). This transition may cause visible artifacts because of the practical limitations of the printer.

NOTE: This feature is not available with the PCL driver.

Spot Color Matching

The Spot Color Matching option provides automatic matching of spot colors with their best CMYK equivalents.

• On—The EX7750 uses a built-in table to generate the closest CMYK matches of

spot colors your printer can produce. (New tables are generated when you add new output proﬁles.)The EX7750 uses the CMYK matches determined through SpotOn (see page 3-19).

• Off—The EX7750 uses CMYK equivalents deﬁned by the spot color manufacturer,

such as PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.

1-10 EX7750 Color Management

For jobs that include spot colors, set Spot Color Matching to On unless you are printing press simulations. In that case, set Spot Color Matching to Off and choose the appropriate CMYK Simulation setting (see page 1-12).

For PDF jobs that include spot colors and where the spot colors are not included in the built-in table, setting Spot Color Matching to On retains the spot color originally speciﬁed. The EX7750 references the built-in table to generate the closest CMYK matches of the original spot color.

NOTE: Use the Spot Color Matching option only when printing composites, not when

printing separations.

Spot Color Matching and the PANTONE Coated Color Reference

The PANTONE Coated Color Reference (described in the Fiery Color Reference) prints differently depending on the Spot Color Matching setting.

• On—The EX7750 uses a built-in table or the Spot-On color dictionaries (see

page 3-19) to generate the best matches of the PANTONE colors that your printer

can produce. The PANTONE number is printed below each swatch.

• Off—The EX7750 prints swatches using the CMYK values recommended by

Pantone, Inc. (and used by applications that provide PANTONE color libraries). The CMYK values used to generate the color, as well as the PANTONE number of the color, are printed below each swatch. These CMYK values are printed through the selected CMYK Simulation and Output Proﬁle settings.

NOTE: This feature is not available with the PCL driver.

1-11 Managing color on the EX7750

RGB Source Proﬁle

The RGB source proﬁle setting allows you to deﬁne the characteristics of the RGB data in your document so the appropriate color conversion can occur on the EX7750. Commonly used monitor color spaces are available from the printer driver and from the ColorWise Pro Tools Proﬁle Manager. For special needs, use ColorWise Pro Tools to download custom monitor or scanner proﬁles.

When you specify a setting other than None for the RGB Source Proﬁle, the EX7750 overrides source color space deﬁnitions or proﬁles that other color management systems may have speciﬁed. For example, if you speciﬁed a ColorSync System Proﬁle on your Mac OS computer, the RGB Source Proﬁle setting overrides it. In cases where you do not want this setting to override another speciﬁed source color space, choose the None setting.

When you specify a setting other than None for the RGB Source Proﬁle—since the color space deﬁnitions are overridden—the output from the EX7750 is consistent across platforms. The EX7750 RGB Source Proﬁle options are:

• EFIRGB speciﬁes an EFI-deﬁned color space recommended for users who have no

detailed information about their RGB data.

• sRGB (PC) speciﬁes the industry standard deﬁnition for a generic Windows

computer monitor.

• Apple Standard speciﬁes the deﬁnition of all standard Mac OS computer monitors.

• Other allows you to specify custom RGB source settings. If you choose Other as the

RGB Source Proﬁle setting, you must choose settings for the Gamma, Phosphors, and White Point options.

1-12 EX7750 Color Management

• Sources 1-10 specify the deﬁnitions you download as RGB source proﬁles. For more

information about downloading RGB source proﬁles, see page 3-5.

If you are printing with the PostScript driver from a Windows computer and have Two-Way Communication enabled, the name of each downloaded proﬁle is represented in the RGB Source Proﬁle setting menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded proﬁles appear as Source-1 through Source-10. For more information about Two-Way Communication, see the

User Software Installation Guide.

• None instructs the EX7750 to allow the RGB sources you deﬁned elsewhere, such as

in the application, to be used. When you set RGB Source to None, the appearance of colors will not be independent of the ﬁle type. For example, RGB EPS ﬁles will look different from RGB TIFF ﬁles.

With RGB Source set to None, PostScript RGB data that contains a source color space deﬁnition is converted using the CRD speciﬁed by the Rendering Style option (see page 1-6). Non-PostScript RGB data and PostScript RGB data that does not contain a source color space deﬁnition are converted using a general undercolor

removal (UCR) conversion method.

NOTE: This feature is not available with the PCL driver.

CMYK Simulation Proﬁle

The CMYK Simulation Proﬁle print option allows you to print press proofs or simulations. This setting speciﬁes the offset press standard or other color printing device that you want to simulate. This option affects CMYK data only.

With the Windows printer drivers, you can also view an unlimited number of custom Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can view up to 10 Full custom simulations. The number of custom simulations is limited by the disk space on the EX7750.

1-13 Managing color on the EX7750

If you are printing with the PostScript driver from a Windows computer and have Two-Way Communication enabled, the name of each downloaded or custom proﬁle is represented in the CMYK Simulation Proﬁle setting menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom proﬁles appear as Simulation-1 through Simulation-10. For more information about Two-Way Communication, see the User Software Installation Guide.

The None setting sends your original CMYK data to the printer in its calibrated state, without conversions to simulate another printer. This setting is not generally recommended, unless you want to bypass the conversion by ColorWise and use another color management system.

The CMYK Simulation Proﬁle setting you specify depends on the press standard for which the CMYK data was separated.

•For images that were separated using a custom separation (such as a separation

produced with an ICC proﬁle), choose the corresponding proﬁle on the EX7750 with the CMYK Simulation Proﬁle setting.

•For images that were separated for SWOP, choose SWOP as the CMYK Simulation

Proﬁle setting.

NOTE: To properly simulate a printed image that was separated through the use of an

ICC proﬁle, the same proﬁle must be present on the EX7750. For more information about downloading ICC proﬁles to the EX7750, see “Downloading proﬁles” on page 3-5.

NOTE: This feature is not available with the PCL driver.

1-14 EX7750 Color Management

CMYK Simulation Method

The CMYK Simulation Method allows you to deﬁne your preferred CMYK-to-CMYK conversion technique.

• Quick applies one-dimensional transfer curves to adjust output densities in the cyan,

magenta, yellow, and black channels. This technique leads to pleasant color output from your printer because pure primary colors are not “contaminated” by other

colorants. While it is the fastest simulation method and perfect for drafts, avoid

using it for ﬁnal documents that will be used as press proofs. Other techniques offer more color simulation accuracy, which is expected by prooﬁng applications.

• Full (Source GCR) provides a complete and accurate simulation based on colorimetric

transformations. Hues are preserved, even for primary colors. The Gray

Component Replacement (GCR) level that was speciﬁed in the original (source)

document is also preserved. Full (Source GCR) is therefore an excellent simulation technique for the highest quality press prooﬁng applications.

• Full (Output GCR) is also a complete and accurate simulation method based on

colorimetric transformations. Hues are preserved, even for primary colors. With this method, the Gray Component Replacement (GCR) level that was speciﬁed in the original document is not preserved. Instead, all CMYK data is reseparated using the GCR level speciﬁed by the Output Proﬁle. This simulation technique is similar to traditional ICC color matching methods and is appropriate for most documents designed for the press, but reproduced on your printer.

NOTE: When you specify On for Pure Black Text/Graphics, and specify Full (Output

GCR) for CMYK Simulation Method, the black text and graphics in your document are printed with 100% black-only toner.

NOTE: This feature is not available with the PCL driver.
