xi About this manual Introduction This manual explains how to manage color output on the Toshiba GA-1121, and provides information on calibration and color profiles. This manual is part of a set of documentation that includes manuals for users and system administrators. The other manuals are available at your site—refer to them for a complete description of your Toshiba GA-1121. N OTE : The term “GA-1121” is used in this manual to refer to the Toshiba GA-1121.
xii Introduction • The Fiery Color Reference Glossary defines words in bold—for example, output profile—that appear throughout this manual. Color terms and concepts, such as “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, check the Glossary.
xiii Key features of ColorWise • Define whether RGB data is converted into the full gamut of the copier/printer or whether it is first converted into the gamut of another device, such as a press standard. This feature is helpful for making one device behave like another. It is also useful for evaluating the appearance of the RGB file under different printing conditions without having to reprocess the RGB data each time.
1 1-1 Managing color on the GA-1121 Chapter 1: GA-1121 Color Management The following sections describe the options available from the ColorWise color management system and explains how to customize the color settings for your particular needs. They provide descriptions of the preset ColorWise default settings and cover additional options for users who need to customize ColorWise. For information on PostScript Level 2 or 3 printer drivers, see page 1-16.
1 1-2 GA-1121 Color Management control the printing of these mixed-color documents with features that apply specifically to RGB, CMYK, or spot color data. GA-1121 color management generates CMYK data to be sent to the copier/printer. The following diagram illustrates the print options in the GA-1121 color management process that affect color data conversions. You can access these print options when you send a print job to the GA-1121.
1 1-3 Managing color on the GA-1121 You can specify settings for the following options by selecting print options when you send a job to the GA-1121. Some can also be set as defaults by the administrator during GA-1121 Setup or using ColorWise Pro Tools. Settings specified using print options override the defaults. Some options can be used as what was purchased separately.
1 1-4 GA-1121 Color Management GA-1121 color print option Enable Trapping On/Off Image Smoothing What it does Specify whether or not the job automatically traps text and graphics independently of their application. Trapping is intended to correct the misalignment of solid tints in CMYK images. This option is only available with the PostScript driver. The On setting enhances the print quality of low-resolution images. Automatic/Off/On/Below 90–300 ppi (Other) Gamma 1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/2.

1 1-6 GA-1121 Color Management GA-1121 color print option RGB Separation Output/Simulation (Default set at Setup or with ColorWise Pro Tools) What it does Determines which CMYK color space your original RGB data will be separated into—CMYK for the copier/printer (Output) or CMYK for a specified simulation (Simulation). For more information, see page 1-14. This option is only available with the PostScript driver.
1 1-7 Managing color on the GA-1121 Rendering Style The Rendering Style option specifies a CRD for color conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Adobe Photoshop, select the appropriate Rendering Style. The GA-1121 allows you to select from the four rendering styles currently found in industry standard ICC profiles.
1 1-8 GA-1121 Color Management N OTE : The rendering styles associated with the PCL driver do not match those associated with the PostScript driver. Pure Black Text/Graphics The Pure Black Text/Graphics option affects the printout for black text and vector graphics on a page. Under most circumstances, leave this option set to On.
1 1-9 Managing color on the GA-1121 see the application notes. Also, black text and line art defined as RGB = 0, 0, 0 in office applications (such as Microsoft Word) are converted to single-color black (CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows 2000/XP. To print this single-color black at the maximum toner density of the copier/printer, set the Pure Black Text/Graphics option to On. N OTE : This feature is not available with the PCL driver.
1 1-10 GA-1121 Color Management • With Black Overprint Off, the border of the text or text/graphics is on an edge that has cyan and magenta toners on one side (outside the text) and black toner on the other side (inside the text). This transition may cause visible artifacts because of the practical limitations of the copier/printer. N OTE : This feature is not available with the PCL driver.
1 1-11 Managing color on the GA-1121 • On—The GA-1121 uses a built-in table or, with the Spot-On (available as Option), the Spot-On color dictionaries (see page 3-18) to generate the best matches of the PANTONE colors that your copier/printer can produce. The PANTONE number is printed below each swatch. • Off—The GA-1121 prints swatches using the CMYK values recommended by Pantone, Inc. (and used by applications that provide PANTONE color libraries).
1 1-12 GA-1121 Color Management • Other allows you to specify custom RGB source settings. If you choose Other as the RGB Source Profile setting, you must choose settings for the Gamma, Phosphors, and White Point options. • Sources 1-10 specify the definitions you download as RGB source profiles. For more information about downloading RGB source profiles, see page 3-4.
1 1-13 Managing color on the GA-1121 If you are printing with the PostScript driver from a Windows computer and have Two-Way Communication enabled, the name of each downloaded or custom profile is represented in the CMYK Simulation Profile setting menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as Simulation-1 through Simulation-10. For more information on Two-Way Communication, see the User Software Installation Guide.
1 1-14 GA-1121 Color Management • Full (Source GCR) provides a complete and accurate simulation based on colorimetric transformations. Hues are preserved, even for primary colors. The Gray Component Replacement (GCR) level that was specified in the original (source) document is also preserved. Full (Source GCR) is therefore an excellent simulation technique for the highest quality press proofing applications.
1 1-15 Managing color on the GA-1121 N OTE : The RGB Separation print option should be used in conjunction with the Output Profile or CMYK Simulation Profile print options. • Output converts all RGB colors into the CMYK color space of your copier/printer (when set to the printer’s default), or a customized CMYK color space for your copier/printer (when set to Output 1-10).
1 1-16 GA-1121 Color Management The Combine Separations options are: • Off prints each separation individually. • On combines separations as a single, composite-color document and automatically makes these settings for the following print options: Color Mode (CMYK), Rendering Style (None), Pure Black Text/Graphics (Off ), Spot Color Matching (Off ), or Black Overprint (Off ).
1 1-17 PostScript printer driver for Windows and Mac OS N OTE : The following illustrations and instructions do not apply to all applications. Many applications, such as Adobe PageMaker, Adobe Photoshop, Adobe Illustrator, QuarkXPress, and CorelDRAW, have other color management options in addition to those presented in the printer driver.

2 2-1 An overview of calibration Chapter 2: Color Calibration Calibrating the GA-1121 ensures consistent, reliable color output. This chapter explains how calibration works and provides instructions for all calibration procedures.
2 2-2 Color Calibration N OTE : The procedures described in this chapter are fundamentally the same for Windows and Mac OS computers. The main differences are the interface cable and the port used to connect to the measurement instrument. The illustrations in this chapter describe the Windows version. N OTE : The term computer is used to refer to any computer running ColorWise Pro Tools.
2 2-3 Understanding calibration Calibration allows you to: • Maximize the color reproduction capabilities of the GA-1121. • Ensure consistent color quality over time. • Produce consistent output across GA-1121 servers. • Achieve better color matches when reproducing spot colors, such as PANTONE colors or other named color systems. • Optimize the GA-1121 for using ColorWise rendering styles (CRDs) and CMYK simulations, and for using ICC profiles.
2 2-4 Color Calibration To create a measurement file, print a page of color patches. Then measure the patches using either a color measurement instrument connected to a computer on the network or, if it is available, the print device’s scanner. The new measurements are automatically downloaded to the GA-1121. Output profiles and calibration sets Output profiles and calibration sets define desired calibration results. One or more output profiles and calibration sets are provided with the GA-1121.
2 2-5 Using Calibrator All 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. Save and compare pages you printed at different times. If there is a noticeable change in appearance, calibrate the GA-1121. When you examine the Test Page, all color patches should be visible, even though they may be very faint in the five percent and two percent range.

3 3-1 Chapter 3: ColorWise Pro Tools Designed to give you flexible control of color printing, ColorWise Pro Tools include the following color management tools: • Calibrator (see Chapter 2) • Color Editor • Profile Manager • Spot-On (available as Option) • Color Setup 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 versions.
3 3-2 ColorWise Pro Tools Profile Manager Profile Manager allows you to manage and edit ICC profiles. In the case of the GA-1121, these profiles are divided into RGB Source, Simulation, and Output profiles: • RGB Source contains all monitor profiles resident on the GA-1121. RGB Source profiles are used to define the source color space for RGB colors processed by the GA-1121. N OTE : If you use Photoshop 5.x, 6.x, or 7.
3 3-3 Profile Manager In addition, one or more output profiles are provided with the GA-1121.For information about output profiles, see page 1-15. N OTE : When you use Profile Manager from some Windows NT computers, the default color directory may not be created automatically when ColorWise Pro Tools are installed. Create the color folder in the appropriate directory (for example, C:\WinNT\system32\Color) and Profile Manager will be able to download and upload from the default location as expected.
3 3-4 ColorWise Pro Tools 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 ( ).
3 3-5 Profile Manager • Windows 2000—Winnt\System32\Spool\Drivers\Color • Windows XP/Server 2003—Windows\System32\Spool\Drivers\Color • Mac OS 9.x—System Folder: Preferences : ColorSync Profiles for ColorSync 2.0, and System Folder : ColorSync Profiles for ColorSync 2.5 or later • Mac OS X (v10.2/10.3)—System : Library : ColorSync : Profiles 2. If the desired profile does not appear, click Browse to go to a different directory.
3 3-6 ColorWise Pro Tools For Mac OS computers, this profile must be associated with one of the predefined names (Source-1 through Source-10 for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output) or set as the default before it can be used. For Windows computers, all profiles can appear in the printer driver by their profile descriptions (see “Defining profiles” on page 3-7).
3 3-7 Profile Manager 4. Click OK when you are notified that the profile was successfully uploaded. Delete profiles to ensure that the wrong profiles are not used, and to free up disk space on the GA-1121 (although profiles are small and do not take up much space). TO DELETE PROFILES FROM THE GA-1121 1. Start ColorWise Pro Tools and click Profile Manager. 2. Select the profile you want to delete and click Delete. A Warning dialog box asks you to confirm the deletion.
3 3-8 ColorWise Pro Tools TO DEFINE A CUSTOM SIMULATION PROFILE 1. Start ColorWise Pro Tools and click Profile Manager. Custom profile created with Color Editor For the purposes of this example, assume DIC-new is a custom simulation profile created with Color Editor and, as such, no information is displayed for DIC-new under the heading “Appear in Driver as.” N OTE : You can define custom profiles only. Default profiles are predefined and cannot be changed. 2.
3 3-9 Profile Manager N OTE : Although you cannot delete a preset profile, you can use the name of a preset profile name for your edited profile when you select the “Appear in Driver as” option. This replaces the preset profile with your own profile. 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 Simulation-1 now appears under the “Appear in Driver as” column for DIC-new.
3 3-10 ColorWise Pro Tools 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. Considerations for defining Output Profiles The procedures for defining Output Profiles is similar to the preceding example for defining Simulations profiles. However, note these differences: For output profiles, the predefined custom names are Output-1 through Output-10.
3 3-11 Color Editor Color Editor also has several Edit Modes for editing simulations: • Master—Create a 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, Full (Source GCR), or Full (Output GCR)—Create custom linked simulations.
3 3-12 ColorWise Pro Tools 3. Choose a profile to edit and click Select. Another method is to open the Profile Manager, select a profile, and then click Edit. 4. For a simulation profile, choose Master from the Edit Mode menu. For an output profile, choose Custom from the Edit Mode menu.

3 3-26 ColorWise Pro Tools Center Patch 2. To update the center patch to a neighboring color that more closely matches the target, click the corresponding neighbor patch. Neighboring patches represent variations from the center patch and can be selected if they offer a closer match to the desired color. Clicking one of these patches updates the center patch to the new color and provides a new selection of neighboring colors.
3 3-27 Using Spot-On Saturation generates neighbor patches based on less saturated to more saturated variations of the original color. This variation is displayed from left to right, with the original color remaining in the center of the middle group. Choose a setting from the Color Spacing menu to control the closeness of the neighbor patches. A higher setting generates neighbor patches that differ more noticeably from the center color.
3 3-28 ColorWise Pro Tools 6. Click OK to print the patches. The Print Pattern test page prints the following information: • Center patch color CMYK value • Color spacing • Lightness or Saturation neighbors selected • Output profile selected The goal of the Spot-On Color Search is to find the color values that make a printed color patch match a target, not the screen simulation of it. Printing a Print Pattern of the neighbor color patches allows you to compare the printed patches to the color target.
3 3-29 Using Spot-On The Device Codes option allows you to enter color values between 0 and 255. This option reflects the full range of color values that the GA-1121 can actually reproduce, and provides finer gradations of color than are possible with Percentages. 3.
