Tips for success

The built-in ColorWise color management system of the Fiery XJ ensures that every color job you print looks good. Regardless of the computer you work on, the application you use, and the type of color work you do, your Fiery XJ print device provides high-quality color output without any special effort on your part.
You can also customize the Fiery XJ color management system for particular types of projects or environments. The Fiery XJ provides total flexibility, allowing you to specify color settings on a job-by-job basis.
The following list summarizes the issues you should consider when you create and print a color document.
1. Maintain and calibrate your print device and Fiery XJ Color Server regularly.

Chapter 1: Desktop Color Primer

This chapter covers concepts that are basic to printing in color, including:
• The properties of color
• Printing techniques
• Using color effectively
• Raster images and vector images
• Optimizing files for processing and printing
• Workflow scenarios
If you are already familiar with color theory and digital color printing, you can skip to the last section (page 1-10) for tips on optimizing your files for printing.

The properties of color

What we call “color” is really a perceptual ability unique to humans and a small number of animal species. Color theory is an attempt to systematize the properties of color perception, which by nature is relative and changeable. A color appears different depending on the other colors around it, and individuals vary in their abilities to perceive color.
This section introduces concepts that are basic to color theory. You will encounter some of these concepts (such as hue, saturation, and brightness) when you work with color in applications; others provide useful background information.

Color is a complex

The physics of color

The human eye can see electromagnetic radiation at wavelengths between 400 nanometers (purplish blue) and 700 nanometers (red). This range is called the visible spectrum of light. We see pure Sunlight at midday, which we perceive as white or neutral light, is composed of light from across the visible spectrum in more or less equal proportions. Shining sunlight through a prism separates it into its spectral components, resulting in the familiar rainbow of colors (plate 1).
spectral light
as intensely saturated or pure colors.

Like the sun, most light sources we encounter in our daily environment emit a mixture of many light wavelengths, although the particular distribution of wavelengths can vary considerably. Light from a tungsten light bulb, for example, contains much less blue light than sunlight. Tungsten light appears white to the human eye which, up to a point, can adjust to the different light sources. However, color objects appear different under tungsten light than they do under sunlight because of the different spectral makeup of the two light sources.
The mixture of light wavelengths emitted by a light source is reflected selectively by different objects. Different mixtures of reflected light appear as different colors. Some of these mixtures appear as relatively saturated colors, but most appear to us as grays or impure hues of a color.

CIE color model

In the 1930s, the Commission Internationale de l’Eclairage (CIE) defined a standard
color space
communication of color information. This color space is based on research on the nature of color perception. The CIE chromaticity diagram (plate 2) is a two­dimensional model of color vision. The arc around the top of the horseshoe encompasses the pure, or spectral, colors from blue-violet to red. Although the CIE chromaticity diagram is not perceptually uniform—some areas of the diagram seem to compress color differences relative to others—it is a good tool for illustrating some interesting aspects of color vision.
, a way of defining colors in mathematical terms, to help in the
By mixing any two spectral colors in different proportions, we can create all the colors found on the straight line drawn between them in the diagram. It is possible to create the same gray by mixing blue-green and red light or by mixing yellow-green and blue­violet light. This is possible because of a phenomenon peculiar to color vision called
metamerism
different combinations of spectral light can produce the same perceived color.
Purple colors, which do not exist in the spectrum of pure light, are found at the bottom of the diagram. Purples are mixtures of red and blue light—the opposite ends of the spectrum.

Hue, saturation, and brightness

A color can be described in terms of three varying characteristics:
• Hue—tint (the qualitative aspect of a color—red, green, or orange)
• Saturation—the purity of the color
• Brightness—relative position between white and black.
While the CIE chromaticity diagram (plate 2) conveys hue and saturation, a three­dimensional color model is required to add the brightness component (plate 3).
Many computer applications include dialog boxes in which you choose colors by manipulating hue, saturation, and brightness. For example, Photoshop uses a square Color Picker (plate 4) which can be reconfigured according to your preference.

Additive and subtractive color systems

Color devices used in desktop publishing and printing colors using a set of primary colors that are combined to create other colors. There ar e two methods of creating a range of colors from a set of primary colors. Computer monitors and scanners use the Fiery XJ print devices and offset presses, use the

Additive (RGB) color
Color devices that use the additive color model make a range of colors by combining varying amounts of red, green, and blue light. These colors are called the

A familiar device that uses this color model is the computer monitor (plate 6). Monitors have red, green, and blue display a given color. Scanners create digital representations of colors by measuring their red, green, and blue components through colored filters.

Subtractive (CMY and CMYK) color
The subtractive color model is used in color printing, and in color photographic prints and transparencies. While the additive color model simulates the visible spectrum of color by adding light of three primary hues, the subtractive color model uses a “white ” or neutral light source containing light of many wavelengths. Inks, toners, or other colorants are used to selectively absorb (subtract) certain wavelengths of light that otherwise would be reflected or transmitted by the media in question.
The subtractive primaries are cyan, magenta, and yello w; they absorb r ed, gr een, and blue light, respectively (plate 7). Combining any two subtractive primaries creates a new color that is relatively pure or saturated. For example, you can make red by combining magenta and yellow, which absorb green and blue light, respectively. White occurs when no colorant is applied. Combining all three subtractive primaries in theory yields black, but due to deficiencies of cyan, magenta, and yellow colorants, combining these three primaries actually yields a muddy brown. Black colorant is added to compensate for the deficiencies of cyan, magenta, and yellow colorants, and consequently color printing uses four process colors: Cyan, Magenta, Yellow, and blacK (CMYK). The use of black ink helps in producing rich solid blacks and also allows for improved rendition of black text.
The CMYK colorants used in offset printing and by your Fiery XJ print device are to some degree transparent. When one layer of colorant is applied on top of another, you see the effect of both. To create a range of intermediary colors, a method is required for varying the amount of each colorant that is applied. A technique called halftoning is used in offset printing, while color print devices typically use a proprietary system for applying ink or toner colors that is similar to halftoning.
1-5 Printing techniques

Printing techniques

Until recently, most color printing was done on printing presses using one of several printing techniques—offset lithography, flexography, and gravure, to name a few. All traditional printing techniques require lengthy preparation before a print run can take place. Short-run color printing, including Fiery XJ printing, eliminates most of this preparation. By streamlining the process of color printing, the Fiery XJ makes short print runs economically feasible.
In contemporary offset lithographic printing, digital files from desktop computers are output to an imagesetter, which creates film separations. The film is used to make a prepress proof, which is an accurate predictor of the final print job, allowing an opportunity to make corrections before going to press. Once the proof is approved, the printer makes plates from the film and runs the print job on the press.
computer
Desktop computer
With a Fiery XJ, you simply print the file. The Fiery XJ processes the P ostScript infor­mation in the file and sends four bitmaps (one each for cyan, magenta, yellow, and black) to the print engine. The ease of Fiery XJ printing makes possible experimenta­tion that would be too costly on press, allowing unlimited fine-tuning of color and design elements.

Halftone and continuous tone devices

Halftoning is used in offset printing to print each process color at a different intensity, allowing millions of different colors to be reproduced using only the four process colors. Depending on the required intensity of a given color, ink is placed on paper in dots of different size. The grid of dots used for each ink color is called a screen. Halftone screens are aligned to unique angles designed to eliminate interference patterns called moiré that can arise with halftoning.
Some color print devices are commonly referred to as continuous tone (or “contone”) devices. They do not use traditional halftone screen patterns and angles. H owever, they do apply dots (in some cases very elongated dots or lines) of different sizes to paper in a process similar to halftoning.
Even if your color printing is done exclusively on the Fiery XJ, you will encounter concepts from offset printing if you use high-end graphics applications. For example, color controls in illustration applications such as Illustrator are geared toward specifying color for offset printing using process and spot colors. Many applications allow you to specify the screening used for each printing plate.

Using color effectively

The ability to print in color can greatly increase the effectiveness of your message, whether you are printing a presentation or a newsletter , or pr oofing an ad concept that will later be printed on press. Some potential benefits of using color include:
• Conveying information rapidly by using color cues
• Making use of the emotive aspects of different colors
• Increasing impact and message retention
Color can also be a source of distraction and discord if it is used poorly. This section outlines some tips and concepts that will prove useful as you approach designing color materials.
1-7 Using color effectively

A few rules of thumb

Try some of the following strategies for creating successful color materials:
• Rather than applying colors indiscriminately, use color to aid comprehension. In presentations, graphs, and charts, use color to highlight patterns and emphasize differences.
• In general, fewer colors work better than many colors.
• Use red as an accent color. Red is particularly effective when used in otherwise monochromatic materials.
• Consider the tastes of your target audience when choosing colors.
• Keep a file of printed color pieces that appeal to you or strike you as effective. Refer to it for ideas when designing your own documents.

Color wheel

A color wheel (plate 8) is a helpful tool for understanding the interrelation of colors. The colors on one side of the color wheel, from magenta to yellow, appear to most people to be warm colors, while those on the other side, from green to blue, appear to be cool. The distance between two colors on the color wheel can help predict ho w they will appear when seen side by side.
Colors opposite one another on the wheel are called complements (plate 9), and create a striking contrast side by side. This can be the basis for a bold graphical design, but it is an effect you should use with discretion since it can be visually fatiguing. Other bold combinations to consider are split complements (a color and the two colors adjacent to its complement) and triads (three colors evenly spaced on the color wheel). Colors adjacent to one another on the color wheel result in subtle harmonies.
The color wheel simplifies color relationships for the purpose of clarity, showing only saturated or pure colors. Adding the myriad variations of each hue to the palette (more or less saturated, darker or lighter) creates a wealth of possibilities. Taking a pair of complements from the color wheel and varying the saturation and brightness of one or both colors produces a very different result from the pure complements. Combining a light tint of a warm color with a darker shade of its cooler complement often gives pleasing results. Combining a darker shade of a warm color with a light tint of its cooler complement produces an unusual effect you may like.

Once you have mastered the concept of the color wheel, you have a good framework for experimenting with color combinations. Many books targeted at graphic designers show groups of preselected color combinations. Some are organized by themes or moods, and some are based on a custom color system such as PANTONE. The more you develop a critical facility for judging color combinations, the more you will be able to trust your own eye for color. The Bibliography at the back of this manual includes books on design.

Color and text

It is not a coincidence that the overwhelming majority of text you see is printed in black on white paper. Text in black on white is highly legible and is not fatiguing to read for extended periods. For many color materials, using black text on a white background and confining color to graphic elements and headings is a good choice.
Color text can add flair to documents printed on paper when used skillfully, and is widely used in presentations. When using color text, avoid dazzling text and background combinations created from primary complements, especially red and cyan or red and blue; they are visually fatiguing and hard to read. Color text is more legible when distinguished from its background by a difference in lightness—for example, dark blue text on a light beige background. In addition, using many different colors in a string of text makes for a confused appearance and is hard to read. However, using a single highlight color is an effective way to draw the reader’s eye to selected words. See plate 10 for color text samples.
When using color text, keep in mind that small font sizes typically do not print in color with the same sharpness as in black. In most applications, black text prints exclusively in black toner, while color text usually prints with two or more toners. Any misregistration between the different toners on paper causes color text to lose definition. You can make test prints to find the smallest point size at which color text prints clearly. When using high-end graphics applications that allow you to specify color as percentages of cyan, magenta, yellow, and black, you can create pure cyan or pure magenta text that prints with the same sharpness as black text. (Pure yello w text is extremely hard to read on anything but a dark or complementary background.)
1-9 Raster images and vector images

Registration and trapping

With any print device, there is the possibility that the different toners may print slightly out of register, producing distracting gaps between objects. Trapping is the process of spreading one color slightly into adjacent colors to compensate for any misregistration that might occur when the file is printed. Depending on the job’s makeup, you may need to take trapping into consideration for best printed results. See the Bibliography for sources of information on trapping.
Some Fiery XJ systems include a Combine Separations print option. This option can be used with PageMaker and QuarkXPress to proof trapping, overprinting, and other four-color printing effects before creating film separations. With Combine Separations turned on, separations are printed in color on a single page. The Combine Separations print option also enables you to combine Desktop Color Separations (DCS) files to print at high resolution instead of printing the low-resolution master file. For more information, see the Printing Guide.

Raster images and vector images

Two broad categories of artwork can be printed from a personal computer to a color printer: raster and vector images (plate 11).
A raster image, also referred to as a bitmap, is composed of a grid of pixels, each assigned a particular color value. The grid, when sufficiently enlarged, resembles a mosaic made from square tiles. Examples of raster images include scans and images created in painting or pixel-editing applications, such as Photoshop and Painter.
The amount of information found in a raster depends on its resolution and bit depth. The resolution of a raster describes the density of the pixels and is specified in pixels per inch (ppi). The bit depth is the number of bits of information assigned to each pixel. Black and white rasters require only one bit of information per pixel. For photographic quality color, 24 bits of RGB color information are required per pixel, yielding 256 separate levels of red, green, and blue. For CMYK images, 32 bits per pixel are required.
1-10 Desktop Color Primer

When printing raster artwork, the quality of the output depends on the resolution of the raster. If the raster’s resolution is too low, individual pixels become visible in the printed output as small squares. This effect is sometimes called “pixelation.”
In vector images, picture elements are defined mathematically as lines or curves between points—hence the term “vector.” Picture elements can have solid, gradient, or patterned color fills. Vector artwork is created in illustration and drawing applications such as Illustrator and CorelDRAW. Page layout applications such as QuarkXPress also allow you to create simple vector artwork with their drawing tools. PostScript fonts are vector-based as well.
V ector artwork is r esolution-independent; it can be scaled to any size without danger of pixels becoming visible in printed output.
Optimizing files for processing and printing
The following sections provide tips on how to create image files that produce the highest possible print quality while minimizing the processing time and disk space they require.

Resolution of raster images

While a 72 ppi raster image appears sharp on a monitor, the same image would likely appear pixelated when printed to the Fiery XJ. Color print devices are capable of much greater detail than monitors, and require correspondingly higher resolution image files. However , high-r esolution files can be large, and therefore cumbersome to transmit ov er a network, process for printing, store on disk, and edit.
Beyond a certain threshold, a higher image resolution greatly increases file size while having a minimal effect on output quality. The optimal image resolution depends on the resolution of the final print device. Aim for the resolution that optimizes both file size and output quality.
1-11 Optimizing files for processing and printing

The resolution of a raster image, along with its bit depth and physical dimensions, determine its file size. The following table shows the file sizes of color raster images at different dimensions and resolutions.
File size at:
Image size 100 ppi 150 ppi 200 ppi 400 ppi
RGB/CMYK RGB/CMYK RGB/CMYK RGB/CMYK

5"

In this table, the shaded areas indicate that 200 ppi is typically the best trade-off between image quality and file size. However, higher resolutions (e.g., 250 to 300 ppi) may be needed for offset printing, when quality is of the utmost importance, or for images containing sharp diagonal lines.
To find the best image resolution for your purposes, make test prints of some raster artwork at different resolutions. Start with a high-resolution image (400 ppi) and save versions at progressively lower resolutions, down to 100 ppi, using a pixel-editing application such as Photoshop. Always save a copy of the original high-resolution version in case you need to revert to it. The high-resolution data cannot be recreated from a lower resolution version.

Print the files and examine the output. You will likely begin to see a marked deterioration in output quality at resolutions below 200 ppi, while above 200 ppi the improvement may be very subtle.
100 ppi 200 ppi 300 ppi 400 ppi
Image resolution
Raster images prepared for offset printing may need to be at higher resolutions than needed for proofing on your Fiery XJ.

Scaling

Ideally, each raster image should be saved at the actual size it will be placed into the document and at the optimal resolution for the print device. If the image resolution is correct for the print device, there is no quality advantage to be gained by scaling an image down to a percentage of its actual size. If you scale a large image down to a percentage of its actual size, you incur unnecessary file transfer time because the image data for the entire large image is sent to the printer . If an image is placed multiple times at a markedly different sizes in a document, save a separate version of the image at the correct size for each placement.
If you need to place an image at greater than 100% in a document, remember that the output image resolution is affected. For example, if you scale a 200 ppi image to 200%, the image is printed at 100 ppi.
1-13 Workflow scenarios

Workflow scenarios
Color print jobs can be divided into two categories:
• Short-run print jobs for which the Fiery XJ is the final print device
• Offset print jobs being proofed on the Fiery XJ
For either type of job, issues of effective color usage, trapping, file optimization, and scaling are important ones. The areas of differ ence between the workflows for these two types of jobs are outlined in the following sections.

Short-run color printing

For short-run color jobs printed to the Fiery XJ:
• You can work in either the RGB color model or the CMYK color model (see the application notes). When working with RGB colors, you should take advantage of the color rendering capabilities of the Fiery XJ (see Chapter 2).
• When choosing or defining colors in your application, use the Fiery XJ color reference pages to be assured of predictable results (see Chapter 3).
• When printing, choose the appropriate settings for print options that affect color output (see Chapter 2).
• When printing, make sure the resident calibration on the Fiery XJ is the appropriate one for your job. The Fiery XJ includes a calibration target designed for your print device, but you can also create a custom target to achieve particular color effects (see Chapter 2 and the Job Management Guide, which describes Fiery XJ calibration).
1-14 Desktop Color Primer

Offset printing

For jobs that will be proofed on the Fiery XJ in preparation for being printed on an offset press:
• Work in the CMYK color model only (see the application notes). All elements in your document, including placed images, must be in the CMYK color model to create film separations for printing.
• When choosing or defining colors in your application, use the Fiery XJ color reference pages to be assured of predictable results (see Chapter 3).
• If cost is a factor and the document does not contain CMYK images, consider using two or three PANTONE colors, instead of the standard four process colors (see Chapter 3). This reduces the number of film separations and printing plates needed to print the job.
• If your document contains high-resolution CMYK raster images, you can reduce processing time by saving the images in Encapsulated PostScript (EPS) format with Photoshop using Desktop Color Separations (DCS). A DCS image consists of five separate files—one for each of the CMYK color channels of the image, plus one low­resolution master composite file that you use for placement in the document (see your Photoshop documentation). The low-resolution master file provides a composite preview of the image for screen viewing and is used to print composites. DCS files do not use less disk space than single CMYK files, but they do reduce the amount of time needed to send image data to the printer. DCS files can be used to create film separations as well.
• Use the Combine Separations print option to check for trapping problems (see the Printing Guide).
• Choose the appropriate CMYK Simulation and CMYK Simulation Method settings (see Chapter 2).

Chapter 2: Color Management

This chapter provides information on the factors involved in controlling and managing color output with the objective of achieving predictable color results, including:
• Controlling printed color
• Basics of color management
• Fiery XJ color management
• Optional ICC color management on Mac OS and Windows computers

Controlling printed color

When working with color materials, whether they be presentations, illustrations, or complicated page designs, you make aesthetic decisions about the colors you use. Once you have decided on your goal, you then need to realize it in print. Your color printing system becomes an ally in this creative process to the extent that you can get results that are predictable.
• If you have designed a brochure to print on the Fiery XJ, you want the printed colors to match the design specification.
• If you are printing presentations on the Fiery XJ, you want to preserve the vivid colors in the monitor display.
• If you are working with color that will print on press, you want the Fiery XJ output to match prepress proofs or PANTONE color swatches.
The type of print job and the final print device, Fiery XJ or offset press, determine the methodology you use to achieve optimal results.
No matter what your goals are, two hardwar e factors always impact color print output: print device consistency and the range of colors the print device can print, known as its gamut. These factors are covered briefly in this chapter. Creating successful color documents and presentations also requires an understanding of color management software as it is implemented by the Fiery XJ and on your desktop computer. Most of this chapter is devoted to discussing the various elements of color management that contribute to predictable color results.
2-2 Color Management

Maintaining print device consistency

The factors described below affect print device consistency, as well as color fidelity and overall output quality.
Paper stock and toner
The paper and toner used by your print device can greatly affect printed color . F or best results, use the supplies recommended by the manufacturer of the print device.
Maintenance
Problems such as streaking and insufficient or excessive amounts of one or mor e toners arise when a print device does not receive periodic maintenance or needs major repairs. In addition to having it serviced regularly, monitor the condition of your print device by making standard test prints at regular intervals. You can do this easily by printing the Fiery XJ Test Page. Save the prints and show them to the service technician whenever output densities vary from the norm or other problems appear.
Calibration
Output from color print devices is subject to changes in temperature and humidity, and is prone to drift over time, with a resulting loss in color predictability. For this reason, regular service visits alone do not guarantee consistent results from a print device. Where color accuracy and consistency are crucial, regular calibration of the Fiery XJ and print device is necessary.
Calibration compares the measured toner densities from a color print device to a set of target densities and downloads a software correction to the Fiery XJ that keeps the densities consistent. Calibration also optimizes the Fiery XJ’s color response for use with the Fiery XJ color management system (see page 2-6).
A resident calibration target is specified during Fiery XJ calibration. The administrator or operator can create custom calibration targets as needed for the specific requirements of your site. For information on performing calibration, see the Job Management Guide, which describes Fiery XJ calibration.
2-3 Controlling printed color

Print device color adjustments
Your print device may allow you to adjust printed color manually. You can typically increase or decrease toner intensity on an individual or global basis. These settings may affect Fiery XJ output. Make sure these settings remain the same (preferably at a neutral position) from one print job to the next. Before performing Fiery XJ calibration, make sure these settings are at a neutral position.

Print device gamut

Different color reproduction techniques have different color capabilities, or gamuts. Color transparency films have comparatively large gamuts, as do color monitors. The color gamut that can be produced using process inks or CMYK toners on paper is smaller. This is why some colors that can be displayed on a color monitor, especially bright saturated colors, cannot be reproduced exactly by your Fiery XJ print device— nor, for that matter, can they be reproduced on press using process colors. Moreover, different print devices have different gamuts—some colors that your print device can produce cannot be reproduced on an offset press, and vice versa. The following illustration provides a graphical representation of this concept.
Color transparency film
RGB monitor
Offset press (white)
Other print device
You need to account for the gamut of your print device when designing on a color monitor. When printed, colors that fall outside the print device’s gamut are “mapped” to printable colors. This process, referred to as gamut mapping, takes place when color data is converted or adjusted to meet the color space and gamut requirements of a print device.
2-4 Color Management
2
The Fiery XJ is specially designed to perform gamut mapping at high speed with high quality results. It provides these color management features automatically, using either built-in default settings or settings that you specify for a particular print job. For added flexibility , the F iery XJ color management system can also be used in combination with color management systems on Mac OS and Windows computers (see page 2-11 and page 2-13).

Basics of color management

The past several years have seen progress toward standardization in the field of digital color management systems. Both the Mac OS and Windows 95 operating systems now support a standard format developed by the International Color Consortium (ICC). This ICC format is implemented on Mac OS computers in ColorSync 2.x and on Windows 95 and Windows NT 4.0 computers in Image Color Matching (ICM). More and more software developers are also incorporating color management systems into high-end applications. The Fiery XJ provides a custom color management system that can be used independent of, or together with, platform-based and application­based color management tools.
A color management system, or CMS, is a “ translator ” betw een the color space of the image source (the monitor, or a scanner, for example) and the color space of the target print device. The CMS uses a device-independent color space, such as CIELAB, as its reference point (see page 1-2). To perform its translation, the CMS needs information about the color space of the image source and the color space and gamut of the print device. This information is provided in the form of profiles, often created by the makers of the monitor or print device. The end product of a CMS conversion is a printed document or an image file in the color space and gamut of a particular print device.
NOTE: If color matching between computer display and printed output is critical,
calibrate your monitor as closely as possible to the printed output. For most users, predictability of printed color output is adequate and monitor calibration is not necessary. For information on monitor calibration, see your Photoshop or Illustrator documentation.
2-5 Basics of color management

Color conversion

Before a color document can be printed, the color data in it must be converted to the color space and gamut of the print device. Whether performed by Fiery XJ color management or by an ICC CMS, the process of converting color data for a print device is the same: the CMS interprets RGB image data according to a specified source profile and adjusts both RGB and CMYK data according to a specified target profile.
Color management system
Source profile
Device-independent
color standard
Input data Printed data or file
The source profile defines the RGB color space characteristics of the image’s source— characteristics such as the white point, the gamma, and the type of phosphors used. The target profile defines the color space characteristics and gamut of the target print device. The Fiery XJ (or the ICC CMS) uses a device-independent color standard to translate between the source color space and the target color space.
The Fiery XJ allows you to specify default and override settings for the source color space information and the target profile information (see “Fiery XJ color management” on page 2-6). When you use these settings, you do not need to use the features of other color management systems. Your Fiery XJ user software includes ICC profiles for use with other color management systems if you choose to use them.
Color management systems can also be used to adjust color data to conform to the gamut of a print device other than the one to which you are printing. This process of simulating another print device is commonly used for proofing jobs that will print on an offset press. The Fiery XJ simulation feature is described on page 2-10.

Fiery XJ color management
The Fiery XJ uses a simple and flexible color architecture that produces excellent color results with default settings. It also allows you to customize your color results using various color controls.
The diagram below illustrates the controls in the Fiery XJ color management process that affect color data conversions. With the exception of the resident calibration, you access these controls via print options when you send a print job. Most of these options and their settings are described in subsequent sections of this chapter.
The output of the Fiery XJ color management process is CMYK data that is ready to be sent to the print device. Additional processing may be performed on board the print device before printing begins.

Applies an RGB source space definition to RGB data (see page 2-8). If you choose the Other setting, you can specify particular settings for gamma, phosphors, and white point with the following three options.
Applies the specified gamma value to the RGB source space definition (see page 2-8). To use this print option, you must choose Other as the RGB Source setting.
Applies the specified phosphor (monitor type) information to the RGB source space definition (see page 2-8). To use this print option, you must choose Other as the RGB Source setting.
Applies the specified white point value to the RGB source space definition (see page 2-8). To use this print option, you must choose Other as the RGB Source setting. If you set this option to anything other than Printer’s Default, set the Rendering Style option to Solid Color for best results. The Photographic and Presentation settings of the Rendering S tyle option use pre-defined white point definitions which override the (Other) White Point setting.
Applies a Fiery XJ color rendering style (CRD) to RGB data (see page 2-9).
Performs a color adjustment on all color channels to make the printed output lighter or darker.
Adjusts CMYK color data to simulate an offset press standard or a custom color gamut defined at your site. Choosing None bypasses simulation (see page 2-10).

2-8 Color Management

RGB Source

The RGB Source option is used to provide a source color space definition for RGB data in your document. The setting you specify for this option overrides any source color space profiles you may have specified with other color management systems. For example, if you specified a ColorSync System Profile on your Mac OS computer (see page 2-11), the RGB Source setting overrides it. In cases where you don’t want this setting to override another specified source color space, choose the Off setting.
EFIRGB is recommended for printing to the Fiery XJ. The source color space defined by this setting is optimal for color conversions that will be sent to a Fiery XJ print device. It also allows for consistent output across different platforms.
sRGB (PC) specifies the source space of a generic Windows computer monitor.
Apple Standard specifies the source space 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, P hosphors, and White Point options.
If you set RGB Source to Off, PostScript RGB data (such as RGB EPS images) and nonPostScript RGB data (such as RGB TIFF images) are converted differently by the Fiery XJ color management system.
• PostScript RGB data is converted using the CRD specified by the Rendering Style option (see page 2-9). PostScript RGB data contains its own source color space information which is used as a reference point for the conversion.
• NonPostScript RGB data is converted using a general under-color-removal conversion method. NonPostScript RGB data does not contain source color space information and so cannot be converted using a CRD.

Rendering styles

The Rendering Style option is used to specify a CRD for color conversions. The following table describes the various color rendering styles (CRDs) provided with Fiery XJ software and provides guidelines on when to use each one. Each color rendering style uses a different gamut mapping method, such as Photographic or Solid, designed for a particular kind of color usage.
The ICC rendering styles referred to in the table are settings you can choose when specifying a target profile with an ICC color management system (see the application notes.)
Fiery XJ rendering style: Best used for:
Photographic—Preserves tonal relationships in images
rather than exact colors. This rendering style maps out­of-gamut RGB colors to printable CMYK colors in a way that retains differences in lightness. Color accuracy is sacrificed slightly in favor of presenting color relationships in the way the human eye perceives them. Photographic rendering typically gives less saturated output when printing out-of-gamut RGB colors than Solid Color rendering does.
Presentation
rendering style does not try to match printed colors precisely to displayed colors but instead provides vibrant, dense colors. Photographic images, however , are treated the same way as by the Photographic rendering style.
Solid Color—Provides best color accuracy and preserves
the saturation of displayed colors. This rendering style matches RGB colors to printable CMYK equivalents wherever possible and maps out-of-gamut RGB colors to the closest printable colors.
None
—Creates bright saturated colors. This
—No CRD is applied

CMYK Simulation

There are several print option settings that affect output when printing press proofs or simulations. These options affect CMYK data only.
The CMYK Simulation setting specifies the offset press standard or other color gamut that you want to simulate. You can also create up to five custom Quick simulations and five custom Full simulations using the Fiery Print Calibrator (see the Job Management Guide).
The CMYK Simulation setting you should specify depends on the press standard for which the CMYK data was separated. For example, for images that were separated for SWOP, choose SW OP-Coated as the CMYK S imulation setting. For images that were separated using a custom separation (such as a device-specific separation or a separation produced with an ICC profile), choose None as the CMYK Simulation setting.

CMYK Simulation Method

The CMYK Simulation Method setting specifies the quality of simulation to perform. Quick simulation applies one-dimensional transfer curves that adjust output density only. Full simulation provides a more complete and accurate simulation by applying four-dimensional transfer curves that adjust hue as well as output density. Depending on image size and resolution, Full simulation may take more time than Quick simulation.
Spot Color Matching
The Spot Color Matching option provides automatic matching of P ANTONE library colors with their best CMYK equivalents.
• On—The Fiery XJ uses its built-in lookup table to generate the closest CMYK matches of PANTONE colors your print device can produce.
• Off—The Fiery XJ uses the CMYK equivalents defined by your application to print PANTONE colors.
For jobs that contain P ANT ONE library colors, set Spot Color Matching to On unless you are printing press simulations. When printing press simulations, set Spot Color Matching to Off and choose the appropriate CMYK Simulation setting (see page 2-10).
2-11 Optional ICC color management for advanced users

The Spot Color Matching option can be used 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 3-6) prints differently depending on the Spot Color Matching setting.
• On—When you print the PANT ONE Coated Color Reference, the F iery XJ uses its built-in lookup table to generate the best matches of the PANTONE colors that your print device can produce. The PANTONE number is printed below each swatch.
• Off—When you print the PANTONE Coated Color Reference, the Fiery XJ 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 belo w each swatch.

Optional ICC color management for advanced users

This section describes how the ICC color management systems implemented on Mac OS and Windows platforms can be used in combination with Fiery XJ color management. You do not need to use the Mac OS or Windows color management systems to get good color printing results—the Fiery XJ provides its own built-in color management. This information is provided for advanced users with particular customization requirements.
Color management on Mac OS computers
The Mac OS includes the ICC ColorSync 2.x color management system. The AdobePS 8.5.1 printer driver (included in the Fiery XJ user software) supports ColorSync 2.x features and all other P ostScript Level 2 and 3 printing features. You can use the AdobePS printer driver to control color conversions of RGB data with ColorSync profiles. Some PostScript applications also provide independent color management features that use ColorSync profiles.
To use the AdobePS driver to perform color management, choose the ColorSync Color Matching setting and specify a ColorSync printer profile when you print (see page 4-2). With these settings, the AdobePS driver performs color conversions and

sends the resulting color data to the Fiery XJ. For information on color management tools provided with applications, see the application notes.

You can specify a ColorSync source color profile for your Mac OS computer with the ColorSync System Profile Control Panel (see Getting Started ). The recommended source color profile for printing to your Fiery XJ print device is the EFIRGB ICC profile included in your Fiery XJ user software. The source color space defined by this profile is the same as that defined by the EFIRGB setting of the RGB Source option (see page 2-8).
The RGB Source setting overrides the ColorSync System Profile setting for RGB data sent to the Fiery XJ. If you do not want the ColorSync profile setting to be overridden, set the RGB Source print option to Off.
The RGB Source setting does not override other source profile settings in cases where you use the printer driver or your application’s color management system to perform color conversions. For example, if you print using the ColorSync Color Matching setting (as described above), the printer driver performs the color conversion and sends CMYK data to the Fiery XJ. In another example, if you assign a ColorSync source profile to an RGB image placed in a document, the application performs the conversion to CMYK and the assigned source profile is not overridden by the RGB Source setting. In these cases, where CMYK data is sent to the Fiery XJ, choose an appropriate CMYK Simulation setting for the print job.
Target profiles
The target profile, or printer profile, contains information about the color space and gamut of the target print device. If you use the ColorSync Color Matching setting of the AdobePS driver, you must specify the printer profile that ColorSync will use to perform its color conversions.
Some applications let you assign ColorSync target profiles to R GB images you place in a document (see the application notes). When you print the document, the application performs color conversions on the placed images, using the profiles you specified, and embeds the resulting color data in the document. Three rendering styles are included in a ColorSync profile, each tailored for a specific type of color output (see page 2-9).
See Chapter 4 for information on setting print option settings that affect printed color .

Color management on Windows computers

The Windows 95 and Windows NT 4.0 operating systems include the Image Color Matching (ICM) color management system.
• The Adobe PS4 printer driver for Windows 95 (included in your Fiery XJ user software) supports ICM features and all PostScript Level 2 and 3 printing features.
With Windows 95, you can instruct the Adobe PS4 driver to perform color management using ICM. To do this, select the “Use image color matching” option in the Graphics tab of the printer’s Properties dialog box. If the “Use image color matching” option does not appear, make sure that the printer’s ICM profile is installed in the Windows\System\Color folder (for instructions, see G etting Started). With the proper ICM settings, the printer driver performs color conversions and sends the resulting color data to the Fiery XJ.
• The Microsoft PostScript Level 2 Printer Driver for Windows NT 4.0 does not currently support all ICM features.
• The Windows 3.1x operating systems does not support ICM.
• Some PostScript applications also provide independent color management features that use ICM profiles (see the application notes).
Source color space profile
A default source color space is defined for every Windows computer monitor. The RGB Source setting overrides this default source color space (see page 2-8). If you do not want the monitor’s default source color space to be overridden, set the RGB Source print option to Off.
The RGB Source setting does not override other source profile settings in cases where you use the printer driver or your application’s color management system to perform color conversions. For example, if you print with Windows 95 using Image Color Matching (as described above), the printer driver performs the color conversion and sends CMYK data to the Fiery XJ. In another example, if you assign an ICM source profile to an RGB image placed in a document, the application performs the conversion to CMYK and the assigned source profile is not overridden by the RGB Source setting. (See the application notes for information on the color management tools available with different applications.)

Target profiles
The target profile, or printer profile, contains information about the color space and gamut of the target print device. If you use the “Use image color matching” option of the Adobe driver for Window 95, you must install the printer profile that ICM will use to perform its color conversions.
Some applications let you assign ICM target profiles to RGB images that you place in a document (see the application notes). When you print the document, the application performs color conversions on the placed images, using the profiles you specified, and embeds the resulting color data in the document. Three rendering styles are included in an ICM profile, each tailored for a specific type of color output (see page 2-9).
See Chapter 4 for information on print option settings that affect printed color.

Chapter 3: 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 with QuickDraw and GDI applications, such as presentation applications and word processing programs
• Choosing colors with PostScript applications, such as page layout programs, illustration programs, and pixel-editing applications

Working with color

The two main factors that influence how you work with color in your 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.
PostScript applications such as illustration, pixel-editing, and page layout applications use the CMYK color model.
The type of printing you plan for the document—short-run printing on the Fiery XJ versus offset press printing—determines the way you define colors as well as the print option settings you choose.
• For short-run printing on the Fiery XJ, use any type of application and define colors in either RGB or CMYK. If your application provides, you can also choose colors from the PANT ONE Coated color library. Choose the appropriate settings for print options affecting color output (see Chapter 2).
• For offset printing jobs, use a PostScript application and define colors in CMYK or choose colors from the PANTONE Coated color library. Placed images should also be CMYK. Choose the appropriate settings for print options affecting color output (see Chapter 2).
3-2 Working with Color in Applications

Color reference pages

Your Fiery XJ user software includes several types of color reference pages that let you see the range of colors your print device can produce. You can be assured of predictable color results if you use the color reference pages when defining the colors you want to use in your document.
• RGB color reference pages—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 XJ (see page 3-3).
• CMYK pages—a downloadable PostScript file of CMYK color patches in the range of colors your print device can print (see page 3-5).
• PANTONE Coated color reference book—a 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 3-6).
Office applications
PostScript printers such as the F iery XJ must receive P ostScript instructions to print an image or a document. Many applications do not create these P ostScript 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 Apple QuickDraw! to display and print when running on Mac OS computers; they use the Windows Graphics Device Interface (GDI) to display and print when running under Windows. We refer to these QuickDraw and GDI applications as “office applications.”
All office applications handle color similarly , using the same R GB 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 XJ. (An exception to this is a CMYK EPS file placed in the document, which is sent as CMYK data.)
3-3 Office applications
3
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 print device (see page 2-3). When you print the document, out-of-gamut RGB colors are mapped to colors your print device can produce.
• These applications send only RGB data to the Fiery XJ. You control the rendering intent 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 your print device’s color gamut. Fiery XJ color rendering styles are described on page 2-9.
Choosing colors in office applications
Two RGB color reference pages, a Microsoft Word file and a Microsoft Pow erP oint file, are provided with your F iery XJ user software. Print these files using different CRDs to see how the colors appear when printed to the Fiery XJ. For best results, print the color reference page using the same media and CRD 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.

Resident calibration

The resident calibration on the Fiery XJ is applied to all data in the print job, so make sure the resident calibration is the right one for your job. The Fiery XJ includes a calibration target designed for your particular print device; by default, this target is the resident calibration.
In certain cases you may wish to create and use a custom calibration target to achieve particular color effects (see the manual in your documentation set that describes Fiery XJ calibration). If a custom target is resident on the Fiery XJ, the custom calibration is applied to all data except CMYK data to which a CMYK Simulation is applied.

PostScript applications

Most applications used for illustration, pixel editing, and page layout can create the PostScript information they send to PostScript printers or save in PostScript files. Illustrator, Photoshop, PageMaker, QuarkXPress, and FreeHand are all PostScript applications.
PostScript applications work with color in many different ways. Most allow you to choose process colors (by entering a percentage for cyan, magenta, yellow, and black), as well as named colors from a custom color system such as PANTONE. When you print composites, these applications send process-color equivalents for named spot colors to color print devices. In some applications, you can also choose colors using the RGB, HSB, HSL, or other color models.
Generally, PostScript applications send color information to the Fiery XJ in CMYK. An exception to this is RGB images placed in the document which are sent directly to the Fiery XJ (unless you specify special color management settings in your application). In addition, some PostScript applications that allow you to define colors in RGB or other color models can also send the data in those color spaces.
Color controls in PostScript applications are typically designed for printing on an offset press, and some adjustments are required for printing to the F iery XJ. Displayed versions of colors you choose in these applications may not match Fiery XJ output exactly, and named colors may not print accurately on the Fiery XJ, since these colors typically require custom inks.
3-5 PostScript applications
3

Choosing colors in PostScript applications

With PostScript applications, you can create colors using any of the color models supported by the application. All PostScript applications support the CMYK model; some also support the RGB model and other color models based on monitor display values. PostScript applications also allow you to choose named colors using one or more color libraries, such as PANTONE (see page 3-6).
The important thing to remember when creating or choosing colors is that the displayed versions of those colors may not match Fiery XJ output or the output of identically defined colors from other color print devices. For this reason, you should use swatch color matching to ensure predictable color printing results with the Fiery XJ or to match your Fiery XJ color output to colors produced by other print devices.
Swatch color matching
Your Fiery XJ user software includes downloadable PostScript files of reference pages for CMYK colors and PANTONE-equivalent colors. By choosing colors from these reference pages, you can be sure of obtaining the same color from your print device.
For best results, calibrate the F iery XJ before printing the reference pages and your final output.
NOTE: S watch color matching does not match monitor colors to printed colors. For this
you must use a color management system and calibrate your monitor to the color output of your print device.
Using the CMYK color reference pages
The CMYK color reference pages, included with your Fiery XJ user software, let you see how various cyan, magenta, yellow, and black combinations look when printed on your print device. Using the CMYK color reference pages, you can easily determine the CMYK values to specify to obtain the printed colors you want.
3-6 Working with Color in Applications
3
The CMYK color reference file is a PostScript file that prints 11 letter/A4-size pages.
CMYK color reference page
To use the CMYK color reference pages, download the file using Fiery Downloader. The printed pages display groups of color patches in graduated combinations of yellow, magenta, and cyan, and smaller patches that include 25, 50, and 75% black. Refer to these pages to pick colors and specify process color values in your application. (For the location of the CMYK color reference file, see G etting S tarted. F or instructions on using Fiery Downloader, see the Printing Guide.)
NOTE: If you plan to later print your document on press, you may need to adjust the
process values to duplicate the colors from your Fiery XJ.
Using the PANTONE Coated color reference book
The PANTONE Coated color reference book, included with your Fiery XJ user software, can help assure predictable results with colors chosen from the PANTONE Coated color library. The PANTONE Coated color reference book is a PostScript file that prints 19 letter/A4-size pages.
3-7 PostScript applications
3
The information printed by the PANTONE Coated color reference book depends on the setting of the Spot Color Matching option.
• On—Prints swatches of the closest equivalents of PANTONE colors your print device can produce. The equivalent PANTONE color name is printed below each swatch.
• Off—Prints swatches of the CMYK equivalents of PANTONE colors as defined by Pantone. (These are the same CMYK values defined in applications that include PANTONE libraries.) The CMYK values used to produce the color, as well as the PANTONE color number, are printed below each swatch.
To print the PANTONE Coated color reference book, download the file to the Fiery XJ using Fiery Downloader. (For the location of the file on the User Software CD, see Getting Started.) If the default Spot Color Matching setting on the Fiery XJ is not the setting you want to use for printing the PANTONE colors, download the file to the Hold queue. Then use Fiery WebSpooler or the Command WorkStation to override the Spot Color Matching setting.

Resident calibration

The resident calibration on the Fiery XJ is applied to all data in the print job, so make sure the resident calibration is the right one for your job. The Fiery XJ includes a calibration target designed for your particular print device; by default, this target is the resident calibration.
In certain cases you may wish to create and use a custom calibration target to achieve particular color effects (see the manual in your documentation set that describes Fiery XJ calibration). If a custom target is resident on the Fiery XJ, the custom calibration is applied to all data except CMYK data to which a CMYK Simulation is applied.

CMYK simulation

If you are using the Fiery XJ to print proofs for an offset press job or to simulate another print device, choose the appropriate CMYK Simulation and CMYK Simulation Method print option settings.
4-1 What a printer driver does

Chapter 4: Printer Drivers and Print Options

This chapter describes the role of the printer driver in your workflow and explains how to use Mac OS and Windows printer drivers for Fiery XJ printing. It includes the following topics:
• An explanation of what a PostScript Level 2 or 3 printer driver does
• Information on the capabilities of various printer drivers
• Instructions for setting color options with the Adobe PostScript printer drivers for Mac OS, Windows 95, and Windows 3.1x
• Instructions for setting Fiery XJ print options with the Microsoft PostScript Level 2 printer driver for Windows NT 4.0

What a printer driver does

To take full advantage of the features of the Fiery XJ, your print jobs must be sent as PostScript Level 2 (or higher) files. Most applications cannot create this PostScript data directly. It is the function of a printer driver to interpret the instructions generated by the application and convert them into PostScript data.
A PostScript Level 2 or 3 printer driver also allows you to select print options specific to your print device. To do this, the printer driver must be matched with a PostScript printer description file (PPD) for your Fiery XJ. The PPD contains information about the particular features supported by the Fiery XJ and the print device. When you print a job, the printer driver lets you choose among features by specifying print options.
A few PostScript applications (for example, PageMaker 6.5) can send PostScript Level 2 data directly to the print device and present print options within the application interface. Even these applications, however, require that you use a PostScript Level 2 or greater printer driver.
4-2 Printer Drivers and Print Options

Your Fiery XJ user software includes Adobe printer drivers for Mac OS, Windows 95, and Windows 3.1x computers. These are the r ecommended printer drivers for printing to the Fiery XJ.
For Windows NT 4.0 computers, use the Microsoft PostScript Level 2 printer driver included with Windows NT 4.0. Printer descriptions are available on your Fiery XJ User Software CD.
Adobe PostScript Printer Driver for Mac OS
This section explains how to set color management print options with the AdobePS 8.5.1 printer driver for Mac OS. AdobePS is a PostScript 3 driver that can take full advantage of the color features of the Fiery XJ, and lets you save a set of print option settings that you use often.
Before you proceed, make sure you have completed the following procedures:
• Install the AdobePS printer driver and the Fiery XJ PPD as described in Getting Started.
• Select the Fiery XJ in the Chooser and match it with the Fiery XJ PPD.
NOTE: The following illustrations and instructions do not apply to all applications.
Some applications, such as PageMaker 6.5, handle color management settings independently of the printer driver. For information on specific applications, see the application notes.

Setting color management print options

You choose print options from the various panes of the AdobePS driver dialog box.
NOTE: The word “pane” is used to describe the different “pages” that appear in the
driver’s dialog box when you make selections from pull-down menus in the dialog box. Each pane presents a particular set of print options.
To access the initial AdobePS dialog box, choose Print from your application’s File menu.
4-3 Adobe PostScript Printer Driver for Mac OS

The AdobePS driver offers you the following three Color Matching options.
• PostScript Color Matching—This option is intended for use with PostScript Level 2 (or higher) printers such as the Fiery XJ. It provides for color conversion on the Fiery XJ using a color rendering dictionary resident on the printer (i.e., a Fiery XJ CRD) or a color rendering dictionary that is downloaded with the print job. Typically you should use this option for printing to the Fiery XJ.
• ColorSync Color Matching—This option provides for color conversion on the computer using a color rendering dictionary generated by ColorSync from an ICC profile. This option can be used with PostScript Level 2 printers such as the Fiery XJ, but is intended for use with PostScript Level 1 printers, or in cases where the computer’s processing capability exceeds that of the printer, or for use with customized ICC profiles. If you use this option, be sure to specify your custom ICC profile or the Fiery XJ ICC profile as the Printer Profile.
• Color/Grayscale—This option maps color data to grayscale shades for monochrome printers and provides a generic color conversion for color print devices.

Chapter 5: Adobe Photoshop 4.0

This chapter covers features of Photoshop version 4.0 for Mac OS and Windows. The illustrations show only Mac OS dialog boxes, but the information and instructions apply equally to the Windows version of Photoshop. Most of the information presented in this chapter also applies to previous versions of Photoshop.

Before you begin

A special feature of Photoshop allows you to save RGB EPS (PostScript) images that include independent source color space information. This feature is sometimes r eferred to as “PostScript Level 2 tagging” or “RGB tagging.”
Y ou define the sour ce color space to apply to R GB EPS images by specifying a M onitor Setup in Photoshop. This Photoshop-specific source color space definition is overridden by the RGB Source print option setting unless you set RGB Source to Off (see page 2-8).
If you are using a Windows version of Photoshop or Photoshop 2.5 for Mac OS, use the instructions below to ensure proper functioning of the RGB tagging feature.

With Windows versions of Photoshop

If you use any Windows version of Photoshop, you must edit the Photoshop configuration settings file in order to enable PostScript Level 2 tagging for RGB EPS files.
In the Photoshop\Prefs folder, open the Photos40.ini (Photoshop 4.0) or Photos30.ini (Photoshop 3.0) file and append the following line to it:
DISABLERGBTAGS=1
Save the file; the change takes effect the next time you start Photoshop.
5-2 Adobe Photoshop 4.0
5
With Photoshop 2.5 for Mac OS
If you use Photoshop version 2.5 for Mac OS, make sure the plug-in called “Don't Tag RGB PostScript®” is not placed in the Photoshop Plug-ins folder. Otherwise, PostScript Level 2 tagging does not occur for RGB EPS files.
If you remove the plug-in, the change takes effect the next time you start Photoshop.
Defining colors
You can choose colors in Photoshop with various color models including HSB, Lab, RGB, and CMYK. You can also choose named colors from the PANTONE Coated color library in Photoshop. For best results, use the color definition methods described in Chapter 3.
Saving files for importing into other documents
Before saving an RGB EPS file, check the Photoshop Monitor Setup. This setting defines the RGB source color space information that will be included in the RGB EPS image (see page 5-1). You can override this source color space with the RGB Source setting (see page 2-8).
Choose Photoshop EPS or TIFF
Before saving any file, perform any rotating, cropping, and resizing needed. This speeds processing when printing from the application in which the image is placed.
It is recommended that you use the EPS or TIFF file formats to save RGB images that will be imported into other documents and printed to the Fiery XJ. EPS and TIFF files can be imported into virtually all page layout applications.
5-3 Selecting options when printing
5
In the EPS Format dialog box, choose binary encoding and do not include transfer functions or halftone screens. A TIFF preview is compatible with both Mac OS and Windows computers.
If you experience problems printing the document in which you place the image, substitute an ASCII-encoded version of the same image, and print the document again. Binary encoding is much more compact than ASCII encoding, but occasionally causes printing problems with some system configurations.
NOTE: If you choose to try JPEG encoding, keep a backup of the original image saved
with binary encoding until you have seen the printed results of the JPEG-encoded file. The compression used for JPEG encoding may produce unwanted artifacts in the file. If you see unexpected results in the printed output of a JPEG-encoded file, use a binary-encoded version instead.

Selecting options when printing

You can print RGB or CMYK images from Photoshop.
• When you print RGB images, you can choose whether the conversion to CMYK data is performed by the Fiery XJ (using a CRD) or by Photoshop (using Photoshop’s separation settings).
• When you print CMYK images, you can print composites or color separations.

Printing RGB images

Use the following instructions to print RGB images.
Choose whether to print in RGB or CMYK. (With the AdobePS 8.5.1 printer driver for Mac OS, these options appear in the Adobe Photoshop pane of the Print dialog box.)
If you select “Print in R GB,” Photoshop sends RGB data to the Fiery XJ and a CRD is used to perform color conversion. Choose the appropriate print option settings for RGB data (see Chapter 2 and Chapter 4).
If you select “Print in CMYK,” Photoshop performs a color conversion and sends CMYK data to the Fiery XJ. With this setting, RGB Source, Rendering S tyle, and S pot Color Matching settings have no effect.
• If Photoshop is configured for separating to an offset press standard, apply the corresponding CMYK Simulation setting. For example, if Photoshop is configured for separating to SWOP, choose SWOP-Coated as the CMYK setting.
• If Photoshop is configured for a custom separation (not a press standard), choose None as the CMYK Simulation setting or choose the corresponding custom simulation target if one has been created.
5-5 Selecting options when printing

For fastest print times, select JPEG encoding. You should, however, check the printed output carefully for unwanted artifacts that can appear as a result of JPEG compression. If you see unexpected results in the printed output when printing with JPEG encoding, print the job again using Binary encoding.
Choose any other print options you want to use (see Chapter 4).

Printing CMYK images

Use the following instructions to print CMYK images.
Choose an encoding method. (With the AdobePS 8.5.1 printer driver for Mac OS, these options appear in the Adobe Photoshop pane of the Print dialog box.) For fastest print times, select JPEG encoding. You should, however, check the printed output carefully for unwanted artifacts that can appear as a result of JPEG compression. If you see unexpected results in the printed output when printing with JPEG encoding, print the job again using Binary encoding.
5-6 Adobe Photoshop 4.0
5
Choose any other print options you want to use (see Chapter 4). RGB Source and Rendering Style settings have no effect on CMYK images. The Spot Color Matching setting is also irrelevant because Photoshop converts PANTONE colors to CMYK values when you work in CMYK mode.
• If the image was separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, if the image is separated for SWOP, choose SWOP-Coated as the CMYK Simulation setting.
• If the image was separated using a custom separation (not a press standard), choose None as the CMYK Simulation setting or choose the corresponding custom simulation target if one has been created.
6-1 Working with page layout applications

Chapter 6: Page Layout Applications

This chapter provides instructions for printing color documents from Adobe PageMaker 6.5, QuarkXPress 4.02, and QuarkXPress 3.32.
Before printing from these applications, make sure the appropriate printer driver and the Fiery XJ PPD are installed on your computer as described in Getting Started.

Working with page layout applications

The following sections apply to all page layout applications.
Defining colors
Page layout applications generally use the CMYK color model. Some allow you to define colors with other color models and may be able to send that data to the Fiery XJ in those other color models. Generally, however, CRDs (which affect only RGB data) do not affect colors defined in page layout applications. For predictable results with CMYK colors, use the CMYK Color Reference pages when defining colors in page layout applications. See “Choosing colors in PostScript applications” on page 3-5.
NOTE: If the application allows you to define colors in RGB, you should determine
whether it converts the RGB data to CMYK before sending it to the Fiery XJ. If it does, this will determine which Fiery XJ print options effect your job. For example, if the application converts RGB black (defined in your document as R0%, G0%, B0%) to four-color CMYK black when it sends the job to the Fiery XJ, the Pure Black Text/ Graphics option will have no effect when you print the job.
Y ou can also choose named colors fr om the P ANT ONE Coated library. See “Using the PANTONE Coated color reference book” on page 3-6.

Importing images

EPS and TIFF are the recommended formats for images imported into page layout documents. Support for importing other file formats may be provided by individual applications.
6-2 Page Layout Applications
6
All RGB images placed in your document are affected by the RGB Source and Rendering Style settings. The Fiery XJ color management system applies the specified RGB Source setting to all RGB data and then uses the specified Rendering Style (CRD) to perform a color conversion. An exception to this occurs if you assign ICC profiles to RGB images using the application’s color management tools (see “Tips for advanced users”). In this case, the application performs the color conversion of the image and sends CMYK data to the Fiery XJ.
NOTE: To take advantage of RGB Source and Rendering Style settings for images
imported into QuarkXPress 4.02, save the images in the EPS format.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a single CRD may not be suitable for all the images. In this case you may want the photographic images to bypass the CRD altogether. To accomplish this, separate the image to CMYK data with a pixel-editing application such as Photoshop and perform color correction on it. Then save it as an EPS or TIFF file and import it into the document.
Alternatively, you can save the RGB image in TIFF format and assign it an ICC profile and rendering intent when you import it into the document, if your application supports this feature.

CMYK simulation and calibration

You can specify a press simulation target and a press simulation method for the job with print options (see page 2-10). The CMYK Simulation setting affects all CMYK color data sent by the page layout application.
• If the document contains CMYK images that were separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, for images separated for SWOP, choose SWOP-Coated as the CMYK Simulation setting.
• If the document contains CMYK images that were separated for a custom separation (not a press standard), choose None as the CMYK Simulation setting or choose the corresponding custom simulation target.

All RGB images are affected by the resident calibration on the Fiery XJ. CMYK data is also affected if the resident calibration is the device-specific calibration provided with the Fiery XJ. (See the manual in your documentation set that describes Fiery XJ calibration.) If the resident calibration is a custom target created at your site, it is not applied to CMYK data. If necessary , print the T est Page to see which target is currently resident on the Fiery XJ.
Adobe PageMaker 6.5 for Mac OS and Windows
The Windows and Mac OS versions of PageMaker 6.5 are essentially identical. The illustrations in this section show only the Windows version, with the exception of instances where differences exist between the two versions.
PostScript Level 2 interface
PostScript Level 2 features, including color management, are incorporated into the PageMaker 6.5 application interface. When y ou print from P ageMaker 6.5, you specify print options and color settings using PageMaker print dialog boxes, not the printer driver dialog boxes described in Chapter 4. However, you must use a PostScript Level 2 (or higher) printer driver to access Fiery XJ print options when printing from PageMaker.
Windows version requirement
For the Windo ws version of PageMaker 6.5, make sure a copy of the Fiery XJ PPD file is in both of the following folders:
• PM65\RSRC\USENGLSH\PPD4

Assigning ICC profiles to RGB images
When you place a non-EPS RGB image (such as a TIFF, JPEG, or GIF image), you can specify an ICC source profile and a rendering intent for the image. You can assign a unique rendering intent to each image you import.
When you use this feature, PageMaker controls the color conversion of the RGB images (using the specified ICC profiles) and sends CMYK data to the Fiery XJ. The CMYK data produced by these conversions is not separated for offset press standards; therefore you should set the CMYK Simulation print option to None (see “CMYK Simulation” on page 2-10). The RGB Source and Rendering Style settings have no effect on these images.

Chapter 7: Illustration Applications

This chapter provides instructions for using Adobe Illustrator 7.0 for Mac OS and Windows, FreeHand 7.0 for Mac OS and Windows, and CorelDRAW! 7.0 for Windows.
Before printing from these applications, make sure the appropriate PostScript printer driver and the Fiery XJ PPD are installed on your computer as described in Getting Started.

Working with illustration applications

You can print directly from an illustration application or use it to create and save files that will be imported into a page layout document. To print from an illustration application, use the printer driver and the print settings recommended in Chapter 4.
NOTE: These application notes provide instructions for printing composites only.
For instructions on printing color separations, refer to the documentation for your application.
As a general rule, use the EPS file format when saving files with an illustration application.
Defining colors
All illustration applications use the CMYK color model. While some also allow you to define colors using other color models, they all send CMYK data to the Fiery XJ. Consequently, the RGB Source and Rendering Style settings (which affect only RGB data) do not affect colors printed from illustration applications. For predictable results with CMYK colors, use the CMYK Color Reference pages when defining colors (see “Choosing colors in PostScript applications” on page 3-5).
NOTE: If you define colors in RGB and print directly from the application, the
application converts the RGB data to CMYK before sending it to the Fiery XJ. This will determine which Fiery XJ print options affect your job. For example, if the application converts RGB black (defined in your document as R0%, G0%, B0%) to four-color CMYK black when it sends the job to the Fiery XJ, the Pure Black Text/ Graphics option will have no effect when you print the job.

Y ou can also choose named colors fr om the P ANT ONE Coated library. See “Using the PANTONE Coated color reference book” on page 3-6.

Importing images

In general, all images placed into illustration application documents should be in EPS format.
All RGB images placed in your document are affected by the RGB Source and Rendering Style settings. The Fiery XJ color management system applies the specified RGB Source setting to all RGB data and then uses the specified Rendering Style (CRD) to perform a color conversion. An exception to this occurs if you assign ICC profiles to RGB images using the application’s color management tools (see “Tips for advanced users”). In this case, the application performs the color conversion of the image and sends CMYK data to the Fiery XJ.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a single CRD may not be suitable for all the images. In this case you may want the photographic images to bypass the CRD altogether. To accomplish this, separate the image to CMYK data with a pixel-editing application such as Photoshop and perform color correction on it. Then save it as an EPS or TIFF file and import it into the document. Alternatively, you can save the RGB image in TIFF format and assign it an ICC profile and rendering intent when you import it into the document (see the individual application notes in this chapter).

CMYK simulation and calibration

You can specify a press simulation target and a press simulation method for the job with print options (see page 2-10). The CMYK Simulation setting affects all CMYK color data sent by the illustration application.
• If the document contains CMYK images that were separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, for images separated for SWOP, choose SWOP-Coated as the CMYK Simulation setting.
• If the document contains CMYK images that were separated for a custom separation (not a press standard), choose None as the Simulation setting or choose the corresponding custom simulation target.

Chapter 8: Office Applications
This chapter provides instructions for printing color documents from QuickDraw and GDI applications such as presentation, spreadsheet, and word processing applications. You can use these instructions with the Microsoft Office 97 and Microsoft Office 95 suite of applications and Persuasion v3.0.
Working with office applications
Before printing from these applications, make sure the appropriate printer driver and the Fiery XJ PPD are installed on your computer as described in Getting Started. The Fiery XJ color management system provides complete color management for jobs printed from office applications.
Defining colors
Office applications use the RGB color model. For instructions on defining colors, see “Choosing colors in office applications” on page 3-3.
Working with imported files
Use EPS format files for all raster images you import into office applications. They print at their full resolution on the Fiery XJ (not at the low resolution used for the screen preview).
Although your application may allow you to import a variety of file formats, EPS format files are recommended for all raster images you want to import; some applications have printing problems when using file formats such as TIFF and PICT.
All RGB images placed in your document are affected by your RGB Source and Rendering Style settings.

Tip for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a single CRD may not be suitable for all the images. In this case you may want the photographic images to bypass the CRD altogether. To accomplish this, separate the image to CMYK data with a pixel-editing application such as Photoshop and perform color correction on it. Then save it as an EPS file and import it into the document.

Selecting options when printing

There are few differences between office applications with regard to Fiery XJ printing. The instructions in this chapter apply to all office applications. Use the instructions in Chapters 2 and 4 to specify print options and color management settings. To specify these options, you must use a PostScript Level 2 (or higher) printer driver, such as the Adobe PostScript Printer Driver.
Because these applications send RGB data to the F iery XJ, your choices of RGB Source and Rendering Style settings are important. Be sure to specify the appropriate CRD for the color effect you want (see “Rendering styles” on page 2-9).

Calibration targets

All color data in the job is affected by the resident calibration on the Fiery XJ. This target may be the one designed for your print device and shipped with the Fiery XJ, or it may be a custom target created at your site (see the manual in your documentation set that describes Fiery XJ calibration). If necessary, print the Test Page to see which target is the currently resident on the Fiery XJ.
