About this manual

This manual is organized to supply you with key information about managing the color output of your Fiery. Chapter 1 discusses the Fiery’s print options and how to get the best color results, and Chapter 2 describes several effective workﬂows. ColorWise Pro Tools™ are discussed in the next two chapters. Chapter 3 covers Calibrator™ and other methods used to calibrate the copier, and Chapter 4 takes you through the features of Proﬁle Manager™, used to manage color proﬁles on the Fiery, and Color Editor™, which lets you customize simulation and output proﬁles. Succeeding chapters offer tips for printing from business and graphics applications. Finally, the appendixes offer information about color theory and color management.

xiv Introduction

Words in bold, for example,

, are terms that appear in the glossary. The bibliography at the end of this manual provides sources for further investigation of color printing issues.

OTE

Starting on this page, color terms and concepts such as “RGB data,” “color

space,” “spot color,” “gamut,” and “source proﬁle” are used throughout this manual. If you are new to desktop color or if any terms are unfamiliar, be sure to read Appendixes A and B or check the glossary.

Key features of ColorWise

ColorWise

Fiery and designed to provide both casual and expert users the best color output for a variety of purposes. The ColorWise default settings were speciﬁcally selected to provide great out-of-box color from many applications and Windows and Mac OS platforms. This means that casual users can get good quality output without knowing about or changing any color settings on the Fiery.

To get consistent color, you should be sure the Fiery is calibrated on a regular basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to calibrate using either the scanner that comes with the copier or an optional densitometer (see Chapter 3).

is the second-generation

color management system

(CMS) built into the

There are a number of features you can use to modify printing results. Depending on your particular needs, you can:

• Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset

press standards

• Match PANTONE colors for the best match when printed using four-color press

conditions or when printed using presses with extra, custom plates

xv Key features of ColorWise

• Select a

color rendering dictionary

(CRD), also called a rendering style, for RGB printing. CRDs allow for rich, saturated printing of presentation graphics; smooth, accurate printing of photographs; and relative or absolute colorimetric rendering for specialized needs

• 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 copier or whether it is ﬁrst converted into the gamut of another device, such as a press standard. This feature is very 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 offers an open color architecture, letting users customize the Fiery to meet new printing needs as they arise. ColorWise supports ICC proﬁles, which are industry standard color proﬁles that deﬁne the color behavior of a device. By downloading ICC proﬁles to the Fiery, it can simulate a custom press (or another copier) as well as accurately print colors from a particular monitor or a particular scanner. In addition, you can create customized ICC proﬁles for the copier.

ColorWise also lets you use any Status T densitometer by importing data in a standard ﬁle format (see Appendix C). In this case, it is important to note that the quality of the instrument used determines the quality of the calibration.

1-1 Managing color on the Fiery

Chapter 1: Fiery Color Management

The ﬁrst part of this chapter describes the options available from the ColorWise color management system and explains how you can customize the color settings for your particular needs. It provides descriptions of the preset default settings of ColorWise and covers additional options for users who need to customize ColorWise.

Beginning on page 1-13 is a detailed explanation of what a PostScript Level 2 or PostScript 3 printer driver does, as well as information on the capabilities of various printer drivers and instructions for setting color options with the PostScript drivers for Windows NT 4.0, Windows 95/98, and Mac OS.

OTE

Most of the color management features described in this chapter are available

only with the PostScript driver, not with the PCL driver.

Managing color on the Fiery

There are three ways to modify the Fiery’s printing behavior:

• You can select ColorWise options for an individual print job using menus that appear from the printer driver.

• You can select most ColorWise options as server defaults from Fiery Setup or from the Control Panel, as described in the to all subsequent print jobs unless you override them.

• You can select some ColorWise options, particularly default and calibration options, from ColorWise Pro Tools. These options include default Simulation Proﬁle (see page 1-8), Simulation Method (see page 1-9), Appear in Driver as (see page 4-8), default Source Proﬁle (see page 1-6), RGB Separation (see page 1-7), and associated calibration set (see page 3-3).

Conﬁguration Guide

. These defaults will apply

ICC proﬁle

settings

Applications can generate color data for the Fiery in many different most common type of color data produced from ofﬁce applications is RGB, while prepress applications generally produce CMYK data. Desktop applications can also generate spot colors such as PANTONE colors. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colors. The Fiery lets users control the printing of these mixed-color documents with features that apply speciﬁcally to RGB, CMYK, or spot color data.

1-2 Fiery Color Management

Fiery color management generates CMYK data to be sent to the copier; additional processing may then be performed before printing begins.

The diagram below illustrates the print options in the Fiery color management process that affect color data conversions. You access these print options when you send a print job to the Fiery. Most of these options and settings are described in subsequent sections of this chapter.

RGB Source Proﬁle is the only color option that applies strictly to RGB color data. The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces.

OTE

For users who are familiar with PostScript 3.0 color, RGB Source Proﬁle affects

all CIEBasedABC color spaces (if the source space is RGB). Also, if you send CMYK data to the Fiery in CIEBasedDEFG format, for example, by choosing PostScript Color Management in Adobe Photoshop, the Fiery’s Rendering Style selection—which normally affects only RGB data—will also affect this CMYK data.

1-3 Managing color on the Fiery

Settings for the following options can be speciﬁed via print options when you send a job to the Fiery. Some can also be set as defaults by the administrator during Fiery Setup. Settings speciﬁed via print options override the defaults.

RGB Separation

Output/Simulation

Determines which CMYK color space your original RGB data will be separated into—CMYK for the copier (Output) or CMYK for a speciﬁed simulation (Simulation) (see page 1-7). It is important to note that when RGB Separation is set to Simulation, RGB colors are affected by CMYK Simulation Proﬁle and CMYK Simulation Method. (This feature is available with the PostScript driver only.)

Adjusts CMYK color data to simulate an offset press standard or a custom color gamut deﬁned at your site. The Match Copy setting bypasses Fiery calibration to match a copy made from the copier glass. Choosing None bypasses simulation (see page 1-8).

OTE: Some of the Simulation settings have slightly different names depending

on the model of copier. (This feature is available with the PostScript driver only.)

Quick simulation applies one-dimensional transfer curves that adjust output density only. Full simulation applies colorimetric transformations that adjust hue as well as output density (see page 1-9). (This feature is available with the PostScript driver only.)

The Output Proﬁle is applied to all data in the print job (see page 1-9). Userdeﬁned output proﬁles can be downloaded to the Fiery with ColorWise Pro Tools (see Chapter 4). (This feature is available with the PostScript driver only.)

The On setting optimizes the quality of black text and line art output (see page 1-10). (This feature is available with the PostScript driver only.)

The On setting overprints black text placed on colored backgrounds; it automatically activates the Pure Black Text/Graphics option (see page 1-11). (This feature is available with the PostScript driver only.)

The On setting enables Fiery matching of PANTONE colors; Off instructs the Fiery to match color output to a Pantone-speciﬁed CMYK combination (see page 1-12). (This feature is available with the PostScript driver only.)

Detailed explanations of how these and other settings affect your print jobs are provided in subsequent sections of this chapter.

1-5 Managing color on the Fiery

Rendering styles

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

1-6 Fiery Color Management

RGB Source Proﬁle

The RGB Source Proﬁle setting allows you to deﬁne the characteristics of the RGB data in your document so that the appropriate color conversion can occur on the Fiery. Commonly used monitor color spaces are available from the driver and from the ColorWise Pro Tools Proﬁle Manager. In addition, for special needs you can 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 Fiery 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 prints from the Fiery will be consistent across platforms. Below are the Fiery’s RGB Source Proﬁle options.

• 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 PC 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 setting, you can choose settings for the Gamma, Phosphors, and White Point options.

• Sources 1-10 specify the deﬁnitions you download as RGB source proﬁles. (For more information about downloading RGB source proﬁles, see Chapter 4.)

• None instructs the Fiery 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.

1-7 Managing color on the Fiery

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 1-5). NonPostScript RGB data and PostScript RGB data that does not contain a source color space deﬁnition is converted using a general undercolor removal conversion method.

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

RGB Separation

The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are converted to CMYK. The name of this option is meant to be descriptive, since the option deﬁnes the color spaces that will be used by the Fiery to “separate” the RGB data into CMYK values.

The two choices available for this option determine whether RGB data is converted into the full gamut of the copier (Output) or whether it is ﬁrst converted into the gamut of another digital printer or a press standard (Simulation). This feature is helpful for making one device behave like another for RGB data. For example, if a high-quality ICC proﬁle is available for another print device, the copier can simulate the behavior of that device.

RGB Separation is also useful for prepress applications. For example, it lets you experiment with the appearance of an RGB scan under different press printing conditions without having to convert the RGB data to CMYK data for each printing condition. When the desired printing condition is found, you can then convert the ﬁle to CMYK, if desired, using the same CMYK simulation proﬁle that was used during the experimentation.

NOTE: The RGB Separation print option should be used in conjunction with the

Output Proﬁle or CMYK Simulation Proﬁle print options.

1-8 Fiery Color Management

• Output converts all RGB colors into the CMYK color space of your copier (when the Output Proﬁle option is set to Printer’s default), or a customized CMYK color space for your copier (when the Output Proﬁle option is set to Output 1-10).

• Simulation converts all RGB colors into the CMYK color space for a speciﬁed simulation (make sure to select the desired simulation with the CMYK Simulation Proﬁle print option).

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.

The CMYK Simulation Proﬁle setting you should 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 Fiery 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 Fiery. For more information about downloading ICC proﬁles to the Fiery, see “Downloading proﬁles” on page 4-5.

• The Match Copy setting bypasses Fiery calibration to simulate the color of a copy produced by the copier. Use this setting when you print images scanned with the Fiery Scan plug-in set to Match Copy.

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

1-9 Managing color on the Fiery

CMYK Simulation Method

The CMYK Simulation Method setting speciﬁes the quality of simulation to perform.

• Quick applies one-dimensional transfer curves that adjust output density only.

• Full provides a more complete and accurate simulation by applying colorimetric transformations that adjust hue as well as output density. The Full Simulation option also maintains the integrity of the black channel by adjusting it independently. This is especially important for images separated using an optimized black generation (UCR/GCR) setting either from a scan or from within an application such as Photoshop.

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

Output Proﬁle

The output proﬁle is applied to all data in the print job, so make sure the selected proﬁle is right for your job. The default output proﬁle consists of both a proﬁle for your copier, describing its color characteristics, and a calibration target that describes the expected behavior of the copier.

In certain cases you may wish to customize the default output proﬁle using the ColorWise Pro Tools Color Editor to achieve particular color effects (see page 4-13). If so, the new customized output proﬁle is applied to all data in the print job. Changing only the output proﬁle does not affect its associated calibration target (since the target is based on a copier model). If you wish, you can edit D-Max values of the calibration target separately (see page 4-7).

You can also use the ColorWise Pro Tools Proﬁle Manager to download your own output proﬁle to the Fiery (see page 4-5). Downloaded output proﬁles are at ﬁrst associated with the default calibration target. As mentioned above, you can edit calibration target D-Max values separately.

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

1-10 Fiery Color Management

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 it is preferable to leave this option set to the On position. When Pure Black Text/Graphics is on, black colors generated by applications are printed using 100 percent black-only toner (for example, RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%). This means the black text and line art will not exhibit halftone artifacts and will not be misregistered, since there is only one toner used. In addition, this setting eliminates blasting. This option is automatically set to On when the Black Overprint option is set to On.

For some jobs it is preferable to turn this option Off, for example, if the page includes gradient ﬁlls that use black. The table below describes the behavior of the Pure Black Text/Graphics option with black data deﬁned in different color spaces.

NOTE: The Pure Black Text/Graphics option can be used only when printing

composites, not when printing separations.

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 Fiery. These elements are not affected by the Pure Black Text/Graphics option. See the application notes for details. Also, black text and line art deﬁned as RGB = 0, 0, 0 in ofﬁce

1-11 Managing color on the Fiery

applications (such as Microsoft Word) are converted to single-color black (CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 2 driver for Windows NT 4.0. To print this single-color black at the maximum toner density of the copier, 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 lets you specify whether or not black text, deﬁned as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%, overprints colored backgrounds.

• On—Black text overprints colored backgrounds, eliminating white gaps and reducing halo affects or misregistration of colors. Setting Black Overprint to On automatically activates the Pure Black Text/Graphics option.

• Off—Black text knocks out colored backgrounds.

NOTE: PostScript applications may perform their own black overprint conversions

before sending the print job to the Fiery.

One example of how you might use this setting is with a page that contains some 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 On, the ﬁnal text portions of the page are overprinted, or combined with the underlying colors. This results in CMYK = 40%, 30%, 0%, 100% for the color used for the text. 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. 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 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). On many devices, this transition causes visible artifacts because of the practical limitations of the copier.

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

1-12 Fiery Color Management

Spot Color Matching

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

• On—The Fiery uses its built-in table to generate the closest CMYK matches of PANTONE colors your copier can produce. (New tables are generated when you add new output proﬁles.)

• Off—The Fiery uses the CMYK equivalents deﬁned by your application to print PANTONE colors.

For jobs that include PANTONE 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 1-8).

NOTE: You can 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 on page 5-7) prints differently depending on the Spot Color Matching setting.

• On—The Fiery uses its built-in table to generate the best matches of the PANTONE colors that your copier can produce. The PANTONE number is printed below each swatch.

• Off—The Fiery prints swatches using the CMYK values recommended by Pantone (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.

1-13 PostScript Printer Drivers and Print Options

PostScript Printer Drivers and Print Options

This section describes the role of the printer driver and explains how to use Windows and Mac OS printer drivers for Fiery printing.

NOTE: The term “PostScript” by itself is used to refer to Adobe PostScript Level 2 or

later. For more information on the PCL drivers for this copier, see the Printing Guide.

What a PostScript printer driver does

To take full advantage of the features of the Fiery, your print jobs must be sent as PostScript data. Since most applications cannot generate PostScript data directly, it is the function of a printer driver to interpret instructions from the application and convert them to PostScript data.

A PostScript printer driver also allows you to select print options speciﬁc to your copier. To do this, the printer driver must be matched with a PostScript printer description ﬁle (PPD) for your Fiery. The PPD contains information about the particular features supported by the Fiery and the copier. The PPD can be thought of as the lines of PostScript code in the ﬁle that are device-speciﬁc. When you print a job, the printer driver lets you choose among features by displaying print options.

A few PostScript applications can send PostScript data directly to the copier and present print options within the application interface. Even these applications, however, require that you use a PostScript printer driver.

Your Fiery user software includes Adobe PostScript printer drivers for Windows 95/98, Windows NT 4.0, and Mac OS computers. These are the recommended printer drivers for printing to the Fiery. (See Getting Started for information on installing printer drivers.)

It is recommended that you set the print options initially in Fiery Setup (see the Conﬁguration Guide). This provides you with a default conﬁguration that is appropriate for most Fiery print jobs.

1-14 Fiery Color Management

Adobe PostScript printer driver for Windows 95/98 and Windows NT 4.0

The printer driver options described in this section can be accessed by clicking Start\Settings\Printers, right-clicking the appropriate PPD name, and selecting Properties (Windows 95/98) or Document Defaults (Windows NT 4.0) from the popup menu. These settings are also accessible from the Print Setup or Page Setup dialog boxes of most applications.

For Window 95/98, the Fiery driver interface enables you to save combinations of settings that you can later access. Additionally, you can choose different settings for individual jobs from the applications you use.

The printer driver writes a PostScript ﬁle containing the instructions generated by your application and the Fiery print options you selected. The printer driver sends the PostScript ﬁle to the Fiery. The Fiery then performs PostScript processing and color conversions and sends raster color data to the print device.

NOTE: The following illustrations and instructions do not apply to all applications.

Many applications, such as PageMaker, Photoshop, Illustrator, QuarkXPress, and CorelDRAW, have other color management options in addition to those presented in the printer driver. For information on speciﬁc applications, see Chapters 6 through 9.

Setting color management print options for Windows 95/98 and Windows NT 4.0

This section explains how to set Fiery color print options with the Adobe PostScript printer driver version 4.3.x for Windows 95/98 and version 5.1 for Windows NT, PostScript 3 printer drivers that can take full advantage of the color features of the Fiery. Before you proceed, make sure you have completed the following procedures described in Getting Started:

• Install the Adobe PostScript Printer Driver version 4.3.x (Windows 95/98) or

Adobe PostScript printer driver for Mac OS

This section explains how to set color management print options with the AdobePS 8.6 printer driver for Mac OS, a PostScript 3 driver that takes full advantage of the color features of the Fiery and lets you save a set of print option settings.

Before you continue, make sure you have completed the following:

• Install the AdobePS printer driver and the Fiery PPD, as described in Getting Started.

• Select the Fiery in the Chooser and set it up with the Fiery PPD.

NOTE: The following illustrations and instructions do not apply to all applications.

Setting color management print options

You choose print options from the various panes of the AdobePS driver dialog box. To access the initial AdobePS dialog box, choose Print from your application’s File menu.

NOTE: The word “pane” is used to describe the different pages that appear in the

driver’s dialog box when you make selections from the pull-down menu at the top left. Each pane presents a particular set of print options.

The AdobePS driver includes the following Color Matching options.

• Color/Grayscale—When this setting is used to print to the Fiery, ColorWise provides all color conversions on the Fiery. Typically, you should use this option when printing to the Fiery.

• PostScript Color Matching—Intended for use with PostScript devices such as the Fiery. It provides for color conversion on the Fiery using a color rendering dictionary resident on the copier (that is, a Fiery CRD) or a color rendering dictionary that is downloaded with the print job.

NOTE: If you use the PostScript Color Matching option, the driver may, depending on

the application you are using, attach a CMYK source deﬁnition to the CMYK data in your document. In such a case, the CMYK data in your document is reseparated using a Fiery CRD. The destination color space for the CRD is determined by the RGB Separation print option. By setting RGB Separation to Simulation, CMYK data is

1-18 Fiery Color Management

printed according to all speciﬁed CMYK Simulation Proﬁle and CMYK Simulation Method settings. By setting RGB Separation to Output, CMYK data is converted to the selected output proﬁle’s CMYK color space.

• ColorSync Color Matching—Provides for color conversion on the host computer. This option can be used with PostScript devices such as the Fiery, but it is intended for use with PostScript Level 1 devices. If you use this option, be sure to specify the Fiery’s ICC proﬁle as the Printer Proﬁle. ColorSync Color Matching is not a suggested color matching method because it does not work in conjunction with all applications and requires that you disable features of ColorWise on the Fiery.

2-1 Workﬂow concepts

Chapter 2: Simple and Advanced Workﬂows

This chapter discusses color management workﬂows used in short-run color printing as well as color prooﬁng on the Fiery. It also gives examples of color management in speciﬁc desktop applications and the interaction between those applications and ColorWise color management.

NOTE: See Chapter 1 for information on the differences in color management support

between the PostScript driver and the PCL driver.

Workﬂow concepts

The term “workﬂow” is used to describe the path a job follows from its creation in a desktop application to ﬁnal printed output. It is helpful to think of the following categories when describing workﬂows:

• Short-run printing versus color prooﬁng for eventual output on an offset press

• RGB, CMYK, and PANTONE color systems

• Desktop color management within an application versus color management on the Fiery, along with the notion that different versions of desktop applications handle color management differently. So it is important to pay close attention to the version of a particular application when considering the workﬂows in this chapter.

Short-run printing versus color prooﬁng

Short-run color printing refers to those jobs for which the Fiery is the ﬁnal print device. Printing jobs to the Fiery in preparation for printing on an offset press is referred to as color prooﬁng. Both types of Fiery print jobs use RGB, CMYK, and PANTONE colors.

• For short-run jobs, bright, saturated colors are often desirable. These are achieved by using the full range of colors available, referred to as the full gamut of copier, or more simply copier CMYK. See “Advanced Workﬂows” on page 2-9 for short-run printing examples.

• Offset jobs proofed on the Fiery require the printed colors to match those from another set of CMYK printing conditions. Colors that are speciﬁed for an offset press require CMYK simulation that is optimized for prooﬁng on the copier. See Advanced Workﬂows on page 2-9 for color prooﬁng examples that simulate the gamut of another digital printer or press standard.

2-2 Simple and Advanced Workﬂows

RGB, CMYK, and PANTONE colors

Colors can be deﬁned in several different color models, the most common being RGB, CMYK, and the PANTONE color matching system. Each model requires a different color conversion at the Fiery. These different color conversion workﬂows are explained below.

• RGB source proﬁles and color rendering dictionaries are used to map RGB colors through a device-independent color space to a destination space, either the full copier gamut in a short-run printing workﬂow or CMYK simulation in a color prooﬁng workﬂow.

• CMYK colors are device-dependent. In a prooﬁng scenario, colors speciﬁed in prepress applications are adjusted so the gamut of the Fiery copier can simulate that of the press. In a short-run printing workﬂow, specifying CMYK colors according to the calibrated copier output eliminates the need for simulation during printing.

• PANTONE spot colors are special inks manufactured to run on an offset printing press. Spot colors can be simulated using CMYK copier toners or process color inks. Two basic workﬂows exist for printing PANTONE colors to the Fiery:

Spot Color Matching On instructs the Fiery to match the output of the copier to the PANTONE spot color.

Spot Color Matching Off instructs the Fiery to match the copier output to a Pantone-speciﬁed process simulation. This CMYK combination is then printed with the CMYK Simulation setting you choose, such as SWOP or Custom, and CMYK Simulation Method set to Full.

2-3 Workﬂow concepts

Desktop versus Fiery color management

A desktop color management system uses ICC proﬁles to convert colors from one device gamut to the next (see Appendix B). The color data is converted when it is passed from one application to another or when the job is sent to the copier, so the processing occurs on your computer as opposed to the Fiery.

One advantage of using ColorWise color management over desktop color management is that your computer is spared the added processing chores; delaying color conversions until the color data reaches the Fiery frees up your computer so you can continue working, and color conversions on the Fiery are in most cases much faster than similar conversions on a host computer.

Managing most or all of your color on the Fiery can also eliminate the potential for undesirable color management-related conﬂicts, such as iterative color conversions and inconsistent color. The Fiery applies global corrections to speciﬁc groups of RGB, CMYK, and PANTONE colors to avoid such conﬂicts.

Finally, by sending RGB ﬁles instead of larger CMYK ﬁles from applications to the Fiery, network trafﬁc is minimized and jobs are generally printed more quickly.

ColorWise uses ICC proﬁles to convert colors to the copier gamut or to simulate other devices such as an offset printing press. ColorWise manages color conversions for all users printing to the Fiery from Windows and Mac OS computers. It lets users follow a simple workﬂow with minimal intervention using robust default settings, while giving advanced users the control and precision they need.

The Fiery can intelligently manage the printed appearance of RGB, CMYK, and PANTONE colors. You can let the Fiery manage color for most short-run color printing jobs without adjusting any settings.

2-4 Simple and Advanced Workﬂows

Simple workﬂows

Every time you print a document containing colors that were not chosen for your speciﬁc copier, those colors need to be converted, which requires color management. Colors can be deﬁned or modiﬁed at any stage in the workﬂow. Since ColorWise is compatible with most other color management systems, you can use the workﬂow most familiar to you.

This section provides examples of color workﬂows that should meet the needs of most Fiery users. For information on speciﬁc desktop applications, see Chapters 6 through 9.

Select your colors wisely

For the colors you see on your monitor to match those on your printed output, they must go through color management, including precise calibration of your monitor and copier. If you are not equipped or inclined to maintain accurate monitor color management, you may opt for an easier approach. First, determine which is more important for you—printed colors or monitor displayed colors.

If displayed colors are more important, trust your eyes and your monitor. Visually select colors on your monitor, but be aware that colors will be optimized only for your monitor. When the document is opened on other monitors, the colors may look different. And even though printed colors may not match those displayed on your monitor, they will still print on the Fiery with good results.

If printed colors are your priority, choose colors from printed samples. By using these sample colors, your printed output will remain consistent regardless of how the colors appear on different monitors. Print the palette of available colors from business applications and then select colors from the printed samples. The Fiery comes with color reference ﬁles on the user software CD (see page 5-2). You can also print the color charts from the Control Panel and select colors by numbers or by name from the printed samples. Advanced applications let you deﬁne colors in the easier-to-control PANTONE and CMYK color spaces. See Chapter 5 for more advice on color selection.

No matter which workﬂow most closely matches your own, you should calibrate your copier regularly (see Chapter 3).

2-5 Simple workﬂows

Select a short workﬂow

Every time colors are converted, performance and color accuracy are affected. Therefore, a workﬂow with fewer steps minimizes the risk of error.

Workﬂow 1 using ColorWise calibration—minimal workﬂow

A minimal color workﬂow requires that you calibrate the copier. Select from printed colors as described above, and set the CMYK Simulation option to None, since simulation is not needed when colors are already deﬁned using CMYK values optimized for your calibrated copier.

NOTE: CMYK Simulation set to None is also useful when you want to prepare an

output proﬁle of your calibrated copier or when you use less efﬁcient color management from the desktop (such as ColorSync or ICM).

In this workﬂow, colors are modiﬁed only at the calibration stage. This is indicated by the black box in the diagram below.

Workﬂow 2 using ColorWise color management—standard workﬂow

Fiery servers are highly optimized for the speciﬁc copier they drive, and ColorWise addresses many issues unique to your copier, including screens, individual toner response, interactions among toners, natural smoothness of blends, and the capability to render PANTONE and custom colors. The Fiery distinguishes text and graphic from image elements, so the black channel information is preserved while parameters used for CMYK color separations are maintained.

Conventional color management systems typically address only color conversions, and they occupy your computer’s processor. When you use ColorWise, jobs leave your computer faster to be processed more quickly on the Fiery.

The recommended standard color workﬂow (indicated by the black boxes in the diagram below) uses ColorWise calibration and color management.

To ensure that the colors you have selected reach the Fiery and ColorWise in a usable form, you should bypass any color management from applications and printer drivers. (Keep in mind, however, that color management from applications and printer drivers is fully supported by ColorWise (see “Advanced workﬂows” on page 2-9).

You must print with the CMYK Simulation print option set to match the CMYK color space in your application when you selected the colors. Any CMYK Simulation setting (except Match Copy) applies calibration, so the response of the copier will appear to be stable.

The recommended values for CMYK Simulation are SWOP in America, Euroscale in Europe, and DIC in Japan—choices that respect the color standard for each region. If colors have been selected speciﬁcally for your calibrated copier, set CMYK Simulation to None.

Workﬂow 3 bypassing ColorWise—not recommended

Bypassing ColorWise color management, while an option, is not a recommended workﬂow. When you bypass ColorWise, you must choose colors using only CMYK formulas designed speciﬁcally for your copier, and you must print with the CMYK Simulation option set to Match Copy. The Fiery still prints pages using your PostScript ﬁles, and drives the copier and its accessories, but it does not perform CMYK color transformation, nor does it consider the calibration of the copier. Calibration is needed in order to get consistent output, since the color response from your copier varies signiﬁcantly depending on wear, heat, humidity, and service.

The diagram below indicates that no modiﬁcations are made to colors in this workﬂow.

Turn off color management in your application

Generally, when printing to the Fiery, it is best to disable color management in the application to ensure that the Fiery receives color data properly and prints it accurately.

Save your ﬁles using color-safe settings

There are several additional steps you can take to ensure color accuracy.

• When saving EPS ﬁles, do not include PostScript Color Management information. This minimizes the risk conﬂicting data and multiple color conversions. PostScript Color Management causes your CMYK and RGB colors to be interpreted by the Fiery as though they were supplied in the Lab color space and, as a result, to be processed by CRDs rather than your simulation settings.

• Include ICC color information in ﬁles. ColorWise will not conﬂict with this information, and such data can be useful to identify the speciﬁc color space used by your ﬁles.

• Do not include halftone and transfer functions.

• Turn off color management in the printer driver.

On Windows machines, if the printer driver offers Image Color Matching options, select Printer Image Color Matching.

On Mac OS computers, you should set the printer driver to include no color management commands at print time (see page 1-17).

The following sections present advanced color management workﬂow examples for three short-run printing and three color prooﬁng situations. Each workﬂow example consists of a brief description, steps for creating and manipulating the ﬁles, a list of the ColorWise settings used in the example, and a table that summarizes the workﬂow.

NOTE: These examples use speciﬁc software packages to represent image-editing,

illustration, page-layout, and business/ofﬁce applications; they are Adobe Photoshop, Adobe Illustrator, QuarkXPress, and Microsoft PowerPoint, respectively.

Short-run printing examples

The following examples illustrate short-run printing on the Fiery.

Photoshop RGB workﬂow

This short-run workﬂow of printing an RGB image from Photoshop is one of the simplest Fiery color workﬂows. In it, RGB data is sent from the application, through the printer driver, to the Fiery, and the RGB-to-CMYK conversion takes place on the Fiery using a CRD rather than in the application. Use the settings illustrated in this workﬂow for printing photographs and artwork.

This document could be created as follows:

• Create an RGB image in Photoshop.

• Print the ﬁle directly to the Fiery.

See Chapter 7 for recommended print settings from Photoshop.

• Use ColorWise to convert the RGB image to copier CMYK, or the full gamut of copier.

3-1 Introduction

Chapter 3: Color Calibration

Calibrating the Fiery ensures consistent, reliable color output. You can calibrate the Fiery with ColorWise Pro Tools using an X-Rite DTP32 automatic scanning densitometer (available as an option). By connecting the densitometer to the serial port on your computer, you can quickly measure color patches and download measurements to the Fiery. You can also obtain measurements from the copier’s builtin scanner and calibrate using AutoCal2 which does not require the use of a densitometer and can be run from ColorWise Pro Tools or from the Control Panel.

NOTE: See Chapter 1 for information on the differences in color management support

between the PostScript driver and the PCL driver.

This chapter explains how calibration works and provides instructions for all calibration procedures. Calibrating with ColorWise Pro Tools is described on page 3-9; calibrating from the Fiery Control Panel with AutoCal2 is described on page 3-15.

For information on advanced calibration and simulation features available with ColorWise Pro Tools, such as editing proﬁles and creating custom proﬁles, see Chapter 4. A format for inputting color measurements from other densitometers is described in Appendix C.

The procedures described in Chapters 3 and 4 are fundamentally the same for Windows 95/98, Windows NT 4.0, and Mac OS computers, including those running Command WorkStation software. The main differences are the interface cable and the port used to connect to the densitometer.

NOTE: The term computer is used to refer to any computer running

ColorWise Pro Tools.

Introduction

Calibration generates curves that adjust for the difference between the actual toner densities (measurements) and the response expected by the output proﬁle.

• Measurements represent the actual color behavior of the copier.

• Calibration sets are sets of measurements.

3-2 Color Calibration

• A calibration target that describes the expected behavior of the copier is contained in each output proﬁle.

Once you have calibrated the Fiery with ColorWise Pro Tools or with AutoCal2 from the Fiery Control Panel, a calibration set is stored on the Fiery. This calibration set will be used when it is associated with an output proﬁle. Every output proﬁle has an associated calibration set. If you have not speciﬁed one, the calibration set associated with the default output proﬁle is used.

NOTE: Changing calibration has the potential to affect all jobs for all users, so you may

want to limit the number of people authorized to perform calibration. An Administrator password can be set from the Fiery Control Panel or in Setup from the Command WorkStation to control access to calibration.

Understanding calibration

Although most users’ needs are met by the default calibration set, the Fiery allows you to choose a calibration set to customize calibration for specialized jobs.

Calibration allows you to:

• Maximize the color reproduction capabilities of the Fiery

• Ensure consistent color quality over time

• Produce consistent output across Fiery servers that are connected to the same print engine

• Achieve better color matches when reproducing spot colors such as PANTONE colors or other named color systems

• Optimize the Fiery for using ColorWise rendering styles (CRDs) and CMYK simulations, and for using ICC proﬁles

How calibration works

Success in obtaining satisfactory print quality from a color server such as a Fiery connected to a copier depends on many factors. Among the most important are establishing and maintaining optimal toner densities. Density is a measure of the light absorbed by a surface. By carefully regulating toner densities, you can obtain consistent printed color.

3-3 Understanding calibration

Even with a calibrated system, toner density is affected by service settings, humidity, and temperature; it also tends to drift over time. Regular measurement detects day-today variations in densities, and calibration corrects for them.

Calibration works by creating calibration curves on the Fiery that compensate for the difference between actual (measured) and desired (target) density values.

Calibration curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that will be made to the data you start with. Transfer functions are often graphed as input or output curves.

The Fiery generates calibration curves after comparing measured values to the ﬁnal target values for each of the four toner colors. The target values are based on the output proﬁle speciﬁed.

Measurements

Measurement files contain numerical values that correspond to the toner density produced by the copier when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.

To create a measurement file, first print a page of color patches from ColorWise Pro Tools or from the Control Panel to the copier. Then measure the patches using either an X-Rite DTP32 densitometer connected to a computer on the network or the copier’s scanner. The new measurements are automatically downloaded to the Fiery.

Output proﬁles and calibration sets

Output proﬁles and calibration sets deﬁne desired calibration results. One or more output proﬁles and one or more calibration sets are provided with the Fiery. When you calibrate the Fiery, you can select the calibration set that corresponds to the typical printing jobs at your site. This same calibration set can be associated with one or more output proﬁles. (For more information on output proﬁles, see page 1-9.)

3-4 Color Calibration

Scheduling calibration

In general, you should calibrate the Fiery at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the copier is subject to wide ﬂuctuations in temperature or humidity, calibrate every few hours. To get the best performance, calibrate whenever there is a noticeable change in print quality.

If you need to split a print job into two or more batches to be printed at different times, it is especially important to calibrate before printing each batch. You should also calibrate the Fiery after copier maintenance. However, because the copier may be less stable immediately after maintenance, wait until you have printed approximately 50 pages before you calibrate.

NOTE: Since printed output from the copier is very sensitive to changes in temperature

and humidity, the copier should not be installed near a window or in direct sunlight, near a heater or air conditioner. Paper is sensitive to climate changes as well. It should be stored in a cool, dry, stable environment, and reams should remain sealed until they are needed.

Print color reference pages, such as the Color Charts (from the Control Panel or from the Command WorkStation) and the color reference pages included with the user software (see Getting Started). All of these pages include fully saturated color patches and pale tints of cyan, magenta, yellow, and black. Images with skin tones offer a very good basis for comparison. You can save and compare pages you printed at different times. If there is a noticeable change in appearance, you should calibrate the Fiery.

If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated with time, show the pages to your copier service technician to ﬁnd out whether adjusting the copier can improve output.

3-5 Using a densitometer

Checking calibration status

You can check whether the Fiery is calibrated, which calibration set and output proﬁle were used, and when the copier was last calibrated:

• Print a Conﬁguration page or Test Page from the Control Panel or the Command WorkStation.

• When you select a calibration set in Calibrator, the last calibration and the user who performed it are displayed.

Using a densitometer

ColorWise Pro Tools are designed to work with the X-Rite DTP32 reﬂection densitometer where color measurements are entered automatically.

NOTE: Measurements from other densitometers can be input using a simple ASCII ﬁle

format (see page C-1).

Setting up the densitometer

Before you calibrate the Fiery, you need to connect, conﬁgure, and calibrate the densitometer to prepare for measuring the printed patches (see “Calibrating the densitometer” on page 3-8). For additional information about setting up and using the densitometer, see the documentation included with it.

3-6 Color Calibration

TO CONNECT THE X-RITE DTP32 TO THE COMPUTER:

1. Turn off the computer.

2. Plug the square end of the interface cable (looks like a modular phone plug) into the I/O port on the side of the X-Rite DTP32.

3. Attach the connector to the computer.

For a Windows computer, insert the 8-pin mini-DIN end of the interface cable into the 9-pin DB9 Connector cable adapter. Insert the 9-pin end into the COM1 or COM2 port on the computer and tighten the screws. If the available port on your computer is 25-pin, you must use the 8-pin-to-25-pin adapter.

7. Use ColorWise Pro Tools to calibrate the Fiery (see page 3-9).

3-8 Color Calibration

Calibrating the densitometer

You will need the black-and-white X-Rite Auto-Cal Strip included with the densitometer. Calibrating the densitometer does not require ColorWise Pro Tools.

TO CALIBRATE THE X-RITE DTP32:

1. Connect the densitometer to the computer and supply power (see page 3-5).

2. From the Main Menu on the X-Rite DTP32 display, press the p1 key once to reach p2.

3. Press the cal key.

Calibrating motor speed is displayed, followed by the words INSERT CAL STRIP.

4. Insert the arrow end of the X-Rite Auto-Cal Strip into the 35mm slot on the front of the X-Rite DTP32 until it stops or the roller starts pulling the strip.

Reading appears momentarily, followed by the density values and CALIBRATION OK.

The densitometer automatically returns to the MAIN MENU.

If UNRECOGNIZABLE STRIP appears, repeat the process or try cleaning the strip (see the X-Rite DTP32 Operating Manual).

5. Start ColorWise Pro Tools and proceed to calibrate the Fiery (see the next section).

Recalibrate the densitometer at least once per month. For critical color, calibrate the densitometer every time you calibrate the Fiery. The densitometer may also warn periodically that it requires calibration.

3-9 Using a densitometer

Calibrating with ColorWise Pro Tools

Using the densitometer or AutoCal2, you can quickly measure color patches and download these measurements to the Fiery using ColorWise Pro Tools Calibrator.

NOTE: Multiple users can be connected to one server with ColorWise Pro Tools, but

only one user at a time can use Calibrator. An error message appears if you try to calibrate when another user is already using ColorWise Pro Tools to calibrate.

ColorWise Pro Tools for Windows and Mac OS computers are fundamentally the same; differences are noted in this chapter. The windows and dialog boxes you see illustrated are the Windows version.

NOTE: Changing the calibration has the potential to affect all jobs for all users, so you

may want to limit the number of people authorized to perform calibration. An Administrator password can be set from the Fiery Control Panel to control access to calibration.

TO CALIBRATE THE COPIER USING CALIBRATOR:

1. Launch ColorWise Pro Tools and connect to the Fiery.

For instructions on conﬁguring the connection to the Fiery, see Getting Started.

2. Click Calibrator.

Expert Mode offers two additional options: Print Pages and View Measurements.

With the Print Pages option, you can print a calibration Comparison Page showing the results of the new measurements with any proﬁle associated with the currently selected calibration set. You can also create a custom comparison page and save it as a PostScript or an Encapsulated PostScript (EPS) ﬁle called CALIB.PS. Then print the ﬁle to the Hold Queue of the Fiery from your application or download it to the Hold Queue with Fiery Downloader. An additional way to create the CALIB.PS ﬁle is to rename any job in the Hold Queue using Command WorkStation.

3-14 Color Calibration

With the View Measurements option, you can view the current set of measurements as a table or as a graph that shows both the measurements and the target curves (shown below).

Output proﬁle name

appears here

When more than one proﬁle use the same target, an additional menu called Plot Against appears at the top right of the window above. It lists all output proﬁles that use that same calibration set. Selecting an output proﬁle from this menu displays the target curves associated with that proﬁle. If each output proﬁle contains a unique calibration target, when you switch proﬁles, the curves displayed also change.

3-15 Calibrating from the Control Panel using AutoCal2

Calibrating from the Control Panel using AutoCal2

You can calibrate the Fiery from the Control Panel using AutoCal2, which calibrates the Fiery using the copier’s built-in scanner as a densitometer. If an Administrator password has been set, you will need it for calibration.

For instructions on using the Fiery Control Panel, see the Conﬁguration Guide.

For troubleshooting during the AutoCal2 procedure, see the Job Management Guide.

4-1 Proﬁle Manager

Chapter 4: ColorWise Pro Tools

ColorWise Pro Tools are color management applications that give you ﬂexible control of color printing. There are three tools:

• Calibrator (see Chapter 3)

• Color Editor

XP12

• Proﬁle Manager

ColorWise Pro Tools for Windows and Mac OS computers are fundamentally the same; differences are noted in this chapter. The windows and dialog boxes illustrated are the Windows version. For information on installing and conﬁguring a connection to ColorWise Pro Tools, see Getting Started.

NOTE: See Chapter 1: for information on the differences in color management support

between the PostScript driver and the PCL driver.

Proﬁle Manager

Proﬁle Manager allows you to manage and edit ICC proﬁles. In the case of the Fiery, these proﬁles are divided into RGB Source, Simulation, and Output proﬁles.

• RGB Source contains all monitor proﬁles resident on the Fiery. RGB Source proﬁles

are used to deﬁne the source color space for RGB colors processed by the Fiery.

• Simulation contains printer proﬁles used to simulate another device on the Fiery.

•

Output contains copier proﬁles that describe the attached copier. For more

information on output proﬁles, see page 1-9.

4-2 ColorWise Pro Tools

NOTE: Changing the Fiery default proﬁles affects all jobs for all users, so you might

want to limit the number of people authorized to use ColorWise Pro Tools by setting an Administrator password.

Several proﬁles are provided with the Fiery, and you can create additional ones as needed by modifying the existing ones. You can also download proﬁles from any workstation to the Fiery. The proﬁles provided are:

RGB Source:

• sRGB (PC)—source color space for a generic Windows computer monitor

• Apple Standard—standard source color space for Mac OS computer monitors with

older versions of ColorSync

• EFIRGB—preset default setting for a Fiery

Simulation:

• SWOP-Coated—the United States press standard

• Euroscale—the European press standard

• DIC—the Japanese press standard

Output:

• Fiery DocuColor 12—proﬁle that describes the copier

• Fiery DocuColor 12 HiGCR —proﬁle that describes the copier, but with a higher level

of black generation than the preset default proﬁle (should be used if gray balance is of a higher priority than print quality)

• Fiery DocuColor 12 Max PPM K—proﬁle that describes the copier but ensures that

equal levels of red, green, and blue will be printed as black-only at 50 pages per minute. Use this proﬁle if you are printing documents that contain both color and black-and-white pages and you want to make sure that the copier prints at the highest speed for each type of page.

NOTE: Fiery DocuColor 12 is built into the Fiery; Fiery DocuColor 12 HiGCR and

Fiery DocuColor 12 Max PPM K can be found on the User CD in the ICM folder (Windows) or ColorSync folder (Mac OS).

4-3 Proﬁle Manager

Setting the default proﬁles

The default proﬁles are applied to all print jobs sent to the Fiery, unless you override them using print options. Therefore, the defaults should be the most commonly used proﬁles.

TO SPECIFY A DEFAULT PROFILE:

1. Launch ColorWise Pro Tools and click Proﬁle Manager.

The left side of the screen lists the ICC proﬁles in the default directory of your computer. The right side lists each of the three types of proﬁles on the Fiery.

The lock icon ( ) to the left of a proﬁle name indicates that the proﬁles cannot be deleted and can be edited only if it is saved under a new name. Only Simulation and Output proﬁles can be edited.

A small icon to the left of a proﬁle name indicates the default proﬁle for each category (RGB Source, Simulation, and Output). If you designate a different proﬁle as the default, the icon appears next to your designated proﬁle. The icon indicating the default RGB Source and Output proﬁles looks like a target ( ). The icon indicating

4-4 ColorWise Pro Tools

2. Select the proﬁle you want as the default for a proﬁle type, and click Proﬁle Settings.

3. In the Proﬁle Settings dialog box, click Default and click Apply.

the default Simulation proﬁle changes in appearance depending on whether the RGB Separation setting in the Global Settings dialog box is set to Simulation ( ) or Output ( ).

4. Click OK.

5. In the main Proﬁle Manager window, the target icon appears next to the new default proﬁle you speciﬁed. Repeat steps 2 through 4 for each type of proﬁle.

If no default is set for RGB Source, then the RGB Source print option is set to None. If no default proﬁle is set for Simulation, then the CMYK Simulation print option is set to None. For more information on print options, see Chapter 1.

For Output there is always a default proﬁle. You can change the Output default by selecting a preset proﬁle you want as the default and clicking Proﬁle Settings. Or you can create a new default under a new name by selecting a preset proﬁle and specifying your choice of the calibration set in the Use Calibration Set pop-up menu and a new name in the Proﬁle Description menu.

4-5 Proﬁle Manager

Downloading proﬁles

The Fiery comes with default proﬁles. It is possible to download additional proﬁles from any computer connected to the Fiery.

TO DOWNLOAD A PROFILE:

1. Launch ColorWise Pro Tools and click the Proﬁle Manager.

The left side of the main Proﬁle Manager windows lists the ICC proﬁles in the default directory of your workstation.

For Windows 95/98, the default directory is \Windows\System\Color. For Windows NT 4.0, the default directory is \Winnt\System32\Color. For Mac OS, the default directory is System Folder:Preferences:ColorSync™ Proﬁles for ColorSync 2.0, and System Folder:ColorSync™ Proﬁles if you have ColorSync 2.5 or later.

2. If the desired proﬁle does not appear, click Browse to go to a different directory.

Browse to the directory containing the proﬁle you want to download and click OK.

4-6 ColorWise Pro Tools

3. When the proﬁle you wish to download appears in the list in the main Proﬁle Manager window, select it.

If the proﬁle is compatible with the Fiery, a green arrow indicates that the proﬁle is available for download. Only output device proﬁles are downloadable to Simulation and Output. Only input device proﬁles are downloadable to RGB Source.

NOTE: On Windows computers, the proﬁles must have an extension of .icc or .icm to

be listed. On Mac OS computers, the proﬁles must have a ﬁle type of proﬁle.

All ICC proﬁles in the selected directory on your computer are displayed in the list in the main Proﬁle Manager window. However, because a proﬁle is listed does not necessarily mean it can be downloaded to the Fiery.

Simulation proﬁles should be only proﬁles of devices for which you want the Fiery to match in terms of color output characteristics. Output proﬁles should be only proﬁles of the device to which your Fiery is connected. Although CMYK printer proﬁles can be downloaded as Simulation or Output, consider how they will be used. If you want the Fiery prints to look like another printer, download that proﬁle as a Simulation. If you have a custom proﬁle of the copier your Fiery is connected to, download that proﬁle as an Output proﬁle.

4. Click the arrow to download the proﬁle and click OK when the download is complete.

The new proﬁle now appears on the list of proﬁles on the right side of the Proﬁle Manager main window.

This proﬁle must be associated with one of the predeﬁned names (Source-1 through 10 for RGB Source, Simulation-1 through 10 for Simulation, or Output-1 through 10 for Output) or set as the default before it can be used. See “Deﬁning proﬁles” on page 4-8.

NOTE: When an output proﬁle is downloaded, it inherits the calibration target of the

current default output proﬁle.

4-7 Proﬁle Manager

Editing proﬁles

XP12

The proﬁles on the Fiery can be customized to meet your speciﬁc needs and the characteristics of your copier using Color Editor either directly or through Proﬁle Manager. See “Color Editor” on page 4-13 for more information on how to edit proﬁles.

Managing proﬁles

With Proﬁle Manager, you can back up proﬁles and delete proﬁles. You should always back up proﬁles before updating Fiery software to ensure that no custom proﬁles are lost.

NOTE: You can back up and delete only those proﬁles that appear in the main Proﬁle

manager window without the lock icon next to them. Locked proﬁles cannot be deleted, but most can be backed up.

TO BACK UP PROFILES:

1. Launch ColorWise Pro Tools and click Proﬁle Manager.

2. Select the proﬁle on the Fiery to upload.

The arrow in the middle of the Proﬁle Manager window turns green and points to the left, indicating the proﬁle is available for upload.

3. Click the green arrow, choose a name and location for the proﬁle, and click Save.

The name will be the ﬁlename of the proﬁle, but the proﬁle description will be the original one or the one you entered in the Proﬁle Settings dialog box.

NOTE: When saving the proﬁle on a Windows computer, be sure to include the

extension .icm. If the extension is not included, additional dialog boxes appear.

4. Click OK when you are notiﬁed that the proﬁle was successfully uploaded.

4-8 ColorWise Pro Tools

Delete proﬁles to make sure no one uses the wrong proﬁle and to free up disk space on the Fiery (although proﬁles are small and don’t take up much space).

TO DELETE PROFILES FROM THE FIERY HARD DISK:

1. Launch ColorWise Pro Tools and click Proﬁle Manager.

2. Select the proﬁle you wish to delete and click Delete.

A Warning dialog box asks you to conﬁrm deletion.

NOTE: You cannot delete preset proﬁles, proﬁles that are currently set as default, or

proﬁles that are linked to any of the predeﬁned custom names, for example Simulation-1.

3. Click Yes to delete the proﬁle.

If you want to delete a proﬁle that is currently set as the default or associated with a custom name, click Proﬁle Settings and uncheck the default option.

Deﬁning proﬁles

Before you can apply any downloaded or edited proﬁle to a print job, that proﬁle must be linked to one of the predeﬁned custom names, or you can set the proﬁle as the default for all print jobs (see setting default proﬁles, page 4-3). There are 10 names available for custom proﬁles— Source-1 through 10 for RGB Source, Simulation-1 through 10 for Simulation, or Output-1 through 10 for Output.

NOTE: A custom simulation proﬁle is used to illustrate this procedure. The same steps

apply for deﬁning custom or downloaded output proﬁles.

For the purposes of this example, assume DIC-new is a custom simulation proﬁle created with Color Editor. As you can see, DIC-new has no information under the heading “Appear in Driver as.”

2. Select DIC-new in the Simulation list, and click Proﬁle Settings or double-click DIC-new.

3. Select the “Appear in Driver as” checkbox, choose one of the predeﬁned custom simulation names (Simulation-1 through Simulation-10) from the pop-up menu, and then click Apply.

Make sure to choose a name that is not already linked with another simulation. If you try to deﬁne two proﬁles with the same name, you will get an error message.

For an output proﬁle, the predeﬁned custom names would be Output-1 through Output-10.

4-10 ColorWise Pro Tools

NOTE: While you cannot delete a preset proﬁle, you can use a preset proﬁle’s name for

your edited proﬁle when you select the “Appear in Driver as” option. This replaces the preset proﬁle with your own proﬁle.

When you choose Proﬁle Settings for an output proﬁle, the Use Calibration Set option also appears. You must calibrate the Fiery with this calibration set before this option has any effect. If you have never measured for this calibration set, default measurements will be used. For more information about calibration sets, see page 3-2.

In Proﬁle Settings you can also change proﬁle descriptions for all non-locked proﬁles.

4. Click OK.

DIC-new will

appear in

driver as

Simulation-1

4-11 Proﬁle Manager

Simulation-1 now appears under the “Appear in Driver as” column for DIC-new. Choosing Simulation-1 from the CMYK Simulation option of the printer driver applies the DIC-new simulation to the print job.

If you do not deﬁne a custom simulation proﬁle, your job will print with CMYK Simulation Proﬁle set to None. If you do not deﬁne a custom RGB Source or Output proﬁle, the default proﬁle is used.

Changing global settings

Use the Global Settings button to open a dialog box where you can set the default simulation method and the proﬁle used for RGB Separation. You can also access information on how all the proﬁles are applied to color data in a job.

4-13 Proﬁle Manager

XP12

Color Editor

Color Editor is used to customize simulation and output proﬁles and can be accessed either directly by clicking its icon in the ColorWise Pro Tools main window, or indirectly through the Proﬁle Manager.

Editing Proﬁles

Color Editor allows you to create custom proﬁles by editing existing simulation or output proﬁles and saving the changes as a new proﬁle. With Color Editor, you can ﬁne-tune a proﬁle on your Fiery to meet your exact speciﬁcations.

NOTE: You cannot edit source proﬁles; only simulation and output proﬁles can be

customized.

Color Editor has two Edit Modes for editing output proﬁles.

• Custom—Use Custom to edit output proﬁles and save customized versions of them.

• % Density—Use % Density to view the calibration target, which is one component

of the output proﬁle. You cannot make changes to the calibration target in this window, but you can import a new target (see page 3-2).

Color Editor also has three Edit Modes for editing simulations.

• Master—Use Master mode to create custom master simulation that affects all print

jobs to which it is applied, unless a linked simulation exists for the selected combination of simulation proﬁle, simulation method and output proﬁle.

• Quick or Full—Use Quick or Full mode to create custom linked simulations. Linked

simulations affect the print job only if the corresponding simulation proﬁle, simulation method, and output proﬁle are selected. If you choose an output proﬁle and simulation method for which you have created a custom linked simulation, that simulation is applied automatically to the job. If you choose a simulation method or output proﬁle for which there is no custom linked simulation, then the master simulation is automatically applied.

4-14 ColorWise Pro Tools

Quick applies one-dimensional transfer curves that adjust output density only, while Full provides a more complete and accurate simulation by applying colorimetric transformations that adjust hue as well as output density (see page 1-9).

NOTE: If you made edits to a master simulation after you created a linked simulation,

the edits are not applied to the linked simulation.

TO EDIT A SIMULATION PROFILE IN MASTER MODE OR AN OUTPUT

PROFILE IN CUSTOM MODE:

1. Launch ColorWise Pro Tools and click Color Editor.

2. Choose Simulation or Output from the View pop-up menu.

Simulation lists the simulation proﬁles resident on the Fiery, and Output lists the output proﬁles resident on the Fiery.

3. Choose a proﬁle to edit and click Select.

NOTE: You can also open the Proﬁle Manager, select a proﬁle, and click Edit.

4-15 Proﬁle Manager

4. For a simulation proﬁle, choose Master from the Edit Mode menu. For an output proﬁle, choose Custom from the Edit Mode menu.

(See page 4-19 for instructions for using Quick or Full mode.)

The eye icons indicate

cyan, magenta, and

yellow are visible and

can be edited

You can use this dialog box to view or edit proﬁles. The graph allows you to view and manipulate color output values.

NOTE: When editing an output proﬁle in Custom mode, the Import button at the

bottom of the Color Editor window lets you import a calibration target ﬁle (.trg) created on another Fiery using the previous version of ColorWise. The current version of ColorWise does not allow you to save a target separately; rather, it saves the target in conjunction with an output proﬁle.

4-16 ColorWise Pro Tools

5. Select the colors you want to edit by turning colors off and on.

6. Click Dot Gain to adjust the dot gain value for simulating press output.

The box with the eye icon to the left of each color indicates whether that color is visible on the graph and will be affected by changes to the curves, brightness, and dot gain controls. You can view and edit all four colors (cyan, magenta, yellow, and black) at once or any combination thereof. Working with only one or two colors at a time helps you ﬁne-tune your adjustments. To turn off a color, click its eye icon. In the example below, cyan and magenta are visible and can be edited.

You can choose either the North American or European standard. Then use the sliders to select the desired Dot Gain:

• The range of values for North American at 50% input are from 0% to 50% gain on

output.

• The range of values for European at 40% input are from 0% to 59% gain on output;

the range of values for European at 80% input are from 0% to 20% gain on output.

A curve with this shape makes a color appear lighter by reducing density in the midtones.

4-17 Proﬁle Manager

If you use Dot Gain values, you should apply the settings ﬁrst so that the curves are deﬂected from their straight-line positions. Then make edits to the new curves. When you adjust Dot Gain values, all existing points on the curve are removed. A warning dialog box gives you the chance to cancel Dot Gain settings before they are applied.

7. Use the plus and minus buttons to adjust brightness.

Changes to the brightness are reﬂected in the curve(s).

8. You can adjust the curves directly by clicking and dragging points on the curve or by entering numbers into the input and output boxes.

The graph maps the input percentage to the output percentage. (These percentages refer to the size of the CMYK halftone dots.) The curve you selected appears, and points along the curve are marked so you can adjust them.

A curve with this shape makes a color appear darker by adding density in the midtones.

A curve with this shape increases contrast.

NOTE: You should adjust points in this way only after you have entered the Dot Gain

and Brightness values.

4-18 ColorWise Pro Tools

9. For an output proﬁle, you can set maximum densities of the C, M, Y, and K channels.

10. When you are ﬁnished, click Save and enter a name for the new proﬁle.

For greater precision, you can key in percentages in the Input and Output boxes or use the arrow keys on the keyboard to adjust the curve. To use the arrow keys, you must ﬁrst click on the curve to establish an anchor point that serves as a reference.

You can enter the maximum densities, called D-Max values, of individual colors for proﬁles that support density settings. D-Max settings are not available when editing Simulation proﬁles in Master mode.

The new custom proﬁle is saved to the Fiery with the new name. If you edit one of the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), you may want to include the original name as part of the new target name, for example, DIC-new, to help you remember the source of the new target.

NOTE: Preset default proﬁles are locked and must be saved with a new name.

Custom proﬁles must be linked to one of the 10 predeﬁned custom proﬁle names (Simulation-1 through 10 for simulation or Output-1 through 10 for output) in order to be accessible from the printer driver. You can create as many custom proﬁles as you want, but a maximum of 10 are available from the printer driver at any one time. See “Deﬁning proﬁles” on page 4-8 for information on linking custom proﬁles to the predeﬁned custom proﬁle names.

NOTE: If you set a custom proﬁle as the default, you can access it from the printer

driver without linking it to one of the predeﬁned custom names. Simply select “Printer’s default” from the printer driver.

4-19 Proﬁle Manager

TO EDIT A SIMULATION IN QUICK OR FULL MODE:

1. Launch ColorWise Pro Tools and click the Color Editor.

2. Choose Simulation from the View pop-up menu, choose the simulation proﬁle to edit, and click Select.

OTE: You can also open the Proﬁle Manager, select a simulation proﬁle, and click

Edit.

3. Choose Quick or Full from the Edit Mode menu, and choose an output proﬁle with which your edited simulation will be linked from the Link with menu.

The edited simulation will be linked with the output proﬁle you select from the “Link with” menu.

NOTE: When editing a simulation proﬁle in Quick mode, the Import button at the

bottom of the Color Editor window lets you import a custom Quick Simulation created on another Fiery using the previous version of ColorWise. The current version of ColorWise does not allow you to save custom Quick or Full Simulations independently; rather, they are saved as components of the same proﬁle.

4-20 ColorWise Pro Tools

4. Edit and save the simulation as described in the procedure (steps 5 through 10) starting on page 4-16.

For this new simulation to be automatically applied to a print job, the CMYK Simulation, Simulation Method, and Output Proﬁle settings must be the same as those used when you edited the proﬁle. If the Simulation Method is different or a different output proﬁle is selected, then the Master simulation is applied.

NOTE: A Simulation Proﬁle can have a custom Master and one or more custom links—

up to two links (Quick and Full) for each output proﬁle on the system.

Undoing simulation edits

You can undo the changes you made to simulations (master and linked) in a number of ways:

• If you have not yet saved your edits, click Done on the Color Editor menu bar, and

don’t save the changes.

• If you saved your edits under a new simulation name and want to delete all edits (in

Master, Quick, and Full modes) to the simulation, see page 4-8.

• If you saved your edits under a new simulation name and want to undo the edits to

one or more linked simulation, use the following procedure.

TO UNDO EDITS MADE TO A CUSTOM LINKED SIMULATION:

1. Launch ColorWise Pro Tools and click either Color Editor or Proﬁle Manager.

2. Choose Simulation from the View pop-up menu, choose the simulation for which you wish to undo edits, and click Select (Color Editor) or Edit (Proﬁle Manager).

4-21 Proﬁle Manager

3. Choose Quick or Full from the Edit Mode menu and choose the output proﬁle with which your unwanted edits are linked from the Link with menu.

4. Click Revert to Master.

OTE: Revert to Master makes the curves for one or more linked simulations match the

last saved master simulation. If you have edited and saved changes to a master simulation, your linked simulations will revert to the changed master, not the original.

5. Indicate whether you want to revert the currently selected linked simulation only, or revert all links of this simulation proﬁle, and click OK.

4-22 ColorWise Pro Tools

6. If you choose “For all Edit Modes and all Proﬁle Links,” a warning dialog box appears. Click OK.

The curves for the linked simulation(s) now match the last saved master simulation exactly.

Checking edited proﬁles

You can view a printed sample of a proﬁle before you save it to the Fiery. You can print a:

• Comparison Page provided with ColorWise Pro Tools, which shows a comparison of

images and colored patches with and without edits.

• User deﬁned CALIB.PS in the Hold Queue.

You can create a custom comparison page and save it as a PostScript or an Encapsulated PostScript (EPS) ﬁle called CALIB.PS and then print the ﬁle to the Hold Queue of the Fiery from your application or download it to the Hold Queue with Fiery Downloader (see page 3-13).

4-23 Proﬁle Manager

TO CHECK A PROFILE:

1. Click Test Print from the Color Editor window.

2. Select a page to print, specify the paper size and input tray (Comparison Page only), and click Print.

For Comparison Page, specify the paper size (LTR/A4 or 11x17/A3) in the Paper Size pop-up menu. In the Input Tray pop-up menu, specify the paper source.

NOTE: If you print the measurement page from the Manual Feed Tray, make sure to

select “MF set at copier” in the Input Tray pop-up menu. Load the appropriate paper in the Manual Feed tray and then select the correct paper size from the copier touch panel display.

5-1 Working with color

Chapter 5: Working with Color in Applications

This chapter provides guidelines for deﬁning colors in your documents to produce the results you want. The following topics are covered:

• Factors affecting how you work with color

• Choosing colors in applications that rely on GDI or QuickDraw to communicate

data to the printer driver, such as presentation applications and word processing programs

• Choosing colors in applications that have the ability to write their own PostScript,

such as some page-layout programs, illustration programs, and pixel-editing applications

NOTE: See Chapter 1 for information on the differences in color management support

between the PostScript driver and the PCL driver.

Working with color

The two main factors that inﬂuence how you work with color in the creation of documents are the application you use and the ﬁnal print device. Applications vary in the methods they provide for choosing colors and in the way they transmit color data to the print device.

• Ofﬁce applications such as presentation software, spreadsheets, and word processing

programs use the RGB color model. They typically transmit only RGB data to the print device.

• Illustration applications use both the RGB and CMYK color models but typically

transmit only CMYK data to the print device.

• Pixel-editing applications use both the RGB and CMYK color models. They also

transmit both RGB and CMYK data to the print device.

The type of printing you plan for the document—short-run color printing on the Fiery versus color printing for eventual printing on an offset press—determines the way you deﬁne colors as well as the print option settings you choose.

5-2 Working with Color in Applications

• For short-run color printing on the Fiery, use any type of application and deﬁne

colors in either RGB or CMYK. If your application supports it, you can also choose colors from the PANTONE color library. Placed images may be limited to the RGB color space. Choose the appropriate settings for print options affecting color output (see page 1-1).

• For color prooﬁng, use an application that writes its own PostScript and deﬁne

colors in RGB, CMYK, or choose colors from the application’s PANTONE color library. Placed images can also be deﬁned in RGB or CMYK. Choose the appropriate settings for print options affecting color output (see page 1-1).

NOTE: The Fiery allows you to use RGB or CMYK data when printing proofs for an

offset press run. However, sending data to an imagesetter most often requires CMYK data.

Color reference pages

Fiery user software includes several types of color reference pages that let you see the range of colors that can be printed on your copier. For predictable color, use the color reference pages when deﬁning the colors in your document.

• RGB Color Reference—a Microsoft Word ﬁle and a Microsoft PowerPoint ﬁle that

let you view the colors available in the standard palettes of ofﬁce applications and see how those colors print on the Fiery (see page 5-4).

• CMYK Color Reference—an 11-page downloadable PostScript ﬁle of CMYK color

patches (see page 5-6).

• PANTONE Coated Color Reference—a 19-page downloadable PostScript ﬁle of

color patches showing CMYK equivalents of PANTONE Coated colors. This ﬁle prints differently depending on the setting of the Spot Color Matching option (see page 5-7).

In addition, you can print RGB, CMY, and PANTONE color charts from the Fiery Control Panel.

5-3 Ofﬁce applications

Ofﬁce applications

When using the PostScript printer driver, copiers such as the Fiery must receive PostScript instructions to print an image or a document. Many applications do not create these PostScript instructions by themselves, and instead rely on the printer driver to create them. Included in this category are most word processors, spreadsheets, and presentation packages. These applications use Windows Graphics Device

Interface (GDI) to display and print when running under Windows and Apple QuickDraw to display and print when running on Mac OS computers. We refer to

these GDI and QuickDraw applications as “ofﬁce applications.”

All ofﬁce applications handle color similarly, using the same RGB color model used for the color monitor display. Most ofﬁce applications allow you to choose colors from a palette of preselected colors; some allow you to add new colors to the palette using a color picker. Although some applications allow you to specify color using the CMY, HSL, and HSV color models, these applications always send RGB color data to the Fiery. (An exception to this is a CMYK EPS ﬁle placed in the document, which is sent as CMYK data.)

When working with color in ofﬁce applications, keep in mind that:

• The range of colors that can be displayed in RGB on your monitor is much larger

than the range of colors that can be printed on your copier. When you print the document, out-of-gamut RGB colors are mapped to colors your copier can produce.

• These applications send only RGB data to the Fiery. You control the rendering style

of the color conversion with your selection of a CRD.

Each CRD uses a different color rendering style, and therefore has a different way of mapping unprintable colors to the color gamut of your copier. Fiery color rendering styles are described on page 1-5.

5-4 Working with Color in Applications

Choosing colors in ofﬁce applications

Two RGB color reference pages, a Microsoft Word ﬁle and a Microsoft PowerPoint ﬁle, are provided with your Fiery user software. Print these ﬁles using different CRDs to see how the colors appear when printed to the Fiery. For best results, print the color reference page using the same print options you plan to use for your ﬁnal document. Select the colors you want to use from the printed version of the RGB color reference page and then use those colors in your document.
