About the Documentat ion About the Documentation This manual is part of a set of Fiery Network Controller for Sharp AR-C360P, herein referred to as the “Fiery,” documentation that includes the following manuals for users and system administrators. Most are available as Acrobat PDF (Portable Document Format) files on the User Documentation CD.
Introduction About this manual This manual explains how to manage color output on the Fiery, 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 Fiery. Note: The term “Fiery” is used in this manual to refer to the Fiery Network Controller for Sharp AR-C360P.
Introduction • Appendix B describes the Simple ASCII File Format (SAIFF), which can be used to import toner density measurements from measurement devices. • 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.
Key features of ColorWise • Select a color rendering dictionary (CRD), also called a rendering style, for RGB printing. CRDs allow for rich, saturated printing of presentation graphics; smooth, accurate printing of photographs; and relative or absolute colorimetric rendering for specialized needs. • Define the source of incoming RGB color data for better screen matching and provide for better color conversion of RGB data with no source information.
1 1-14 Managing color on the Fiery Chapter 1: Fiery Color Management The following sections describe the options available from the ColorWise color management system and explain 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 1-31.
1 1-15 Managing color on the Fiery applications generally produce CMYK data. Desktop applications can also generate spot colors, such as PANTONE colors. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colors. The Fiery allows users to control the printing of these mixed-color documents with features that apply specifically to RGB, CMYK, or spot color data. Fiery color management generates CMYK data to be sent to the printer.
1 1-16 Fiery Color Management CIEBasedDEFG format, for example, by choosing PostScript Color Management in Adobe Photoshop, the Fiery Rendering Style selection—which normally affects only RGB data—will also affect this CMYK data.
1 1-17 Managing color on the Fiery You can specify settings for the following options by selecting print options when you send a job to the Fiery. Some can also be set as defaults by the administrator during Fiery Setup or using ColorWise Pro Tools. Settings specified using print options override the defaults. Fiery color print option Brightness 85% Lightest to 115% Darkest What it does Performs a color adjustment on all color channels to make the printed output lighter or darker.
1 1-18 Fiery Color Management Fiery color print option What it does (Other) Phosphors Applies the specified phosphor (monitor type) information to the RGB source space definition (see page 1-25). To use this print option, you must choose Other as the RGB Source Profile setting. Output Profile The output profile is applied to all data in the print job (see page 1-29). User-defined output profiles can be downloaded to the Fiery using ColorWise Pro Tools.
1 1-19 Managing color on the Fiery Fiery color print option Spot Color Matching On/Off (Default set at Setup or with ColorWise Pro Tools) What it does The On setting enables Fiery-defined matching of spot colors to their best CMYK equivalents. With Spot-On, you can manage and edit these spot color matches (see page 3-81). Off instructs the Fiery to match color output to a CMYK combination specified by the source application for the document (see page 1-23).
1 1-20 Fiery Color Management Rendering Style The Rendering Style option specifies a CRD for color conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Photoshop, select the appropriate Rendering Style. The Fiery allows you to select from the four rendering styles currently found in industry standard ICC profiles.
1 1-21 Managing color on the Fiery Fiery rendering style Absolute Colorimetric—Provides no white point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to a bluish gray. Best used for Situations when exact colors are needed and visible borders are not distracting. It may also be used with PostScript color management to affect CMYK data for simulation purposes.
1 1-22 Fiery Color Management Note: Use the Pure Black Text/Graphics option only when printing composites, not when printing separations. Input black color RGB Pure Black Text/Graphics On Prints 100% black Off With the default profile, prints a rich black using all toners. CMYK Prints only with black toner, because CMYK simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the printer.
1 1-23 Managing color on the Fiery • Text & Graphics—Black text and graphics overprint colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors. • Off—Black text or text/graphics knocks out colored backgrounds. Note: PostScript applications may perform their own black overprint conversions before sending the print job to the Fiery. One example of how you might use this setting is with a page that contains black text on a light blue background.
1 1-24 Fiery Color Management • On—The Fiery uses a built-in table to generate the closest CMYK matches of spot colors your printer can produce. (New tables are generated when you add new output profiles.) With SpotOn, the Fiery uses the CMYK matches determined through SpotOn (see page 3-81). • Off—The Fiery uses CMYK equivalents defined by the spot color manufacturer, such as PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.
1 1-25 Managing color on the Fiery are printed below each swatch. These CMYK values are printed through the selected CMYK Simulation and Output Profile settings. RGB Source Profile The RGB source profile setting allows you to define the characteristics of the RGB data in your document so the appropriate color conversion can occur on the Fiery. Commonly used monitor color spaces are available from the printer driver and from the ColorWise Pro Tools Profile Manager.
1 1-26 Fiery 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 3-66.
1 1-27 Managing color on the Fiery With the Windows printer drivers, you can also view an unlimited number of custom Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can view up to 10 Full custom simulations. The number of custom simulations is limited by the disk space on the Fiery.
1 1-28 Fiery Color Management • Quick applies one-dimensional transfer curves to adjust output densities in the cyan, magenta, yellow, and black channels. This technique leads to pleasant color output from your printer because pure primary colors are not “contaminated” by other colorants. While it is the fastest simulation method and perfect for drafts, avoid using it for final documents that will be used as press proofs.
1 1-29 Managing color on the Fiery The two choices available for this option determine whether RGB data is converted into the full gamut of the printer (see output profile) or is first converted into the gamut of another digital printer or press standard (simulation). This feature is helpful for making one device behave like another for RGB data. For example, if a high-quality ICC profile is available for another print device, the Fiery can simulate the behavior of that device.
1 1-30 Fiery Color Management calibration target (since the target is based on a printer model). You can edit D-Max values of the calibration target separately (see page 3-72). Use the ColorWise Pro Tools Profile Manager to download your own output profile to the Fiery (see page 3-66). Downloaded output profiles are at first associated with the calibration target that is tied to the default output profile. You can edit calibration target D-Max values separately.

2 2-38 An overview of calibration Chapter 2: Color Calibration Calibrating the Fiery ensures consistent, reliable color output. This chapter explains how calibration works and provides instructions for all calibration procedures.
2 2-39 An overview of calibration An overview of calibration Calibration generates curves that adjust for the difference between the actual toner densities (measurements) and the response expected by the output profile. • Measurements represent the actual color behavior of the printer. • Calibration sets are sets of measurements. • A calibration target that describes the expected behavior of the printer is contained in each output profile. After you have calibrated the Fiery, a calibration set is stored.
2 2-40 Color Calibration Understanding calibration Although most users’ needs are met by the default calibration set, the Fiery allows you to choose a calibration set to customize calibration for specialized jobs. Calibration allows you to: • Maximize the color reproduction capabilities of the Sharp ARC360P. • Ensure consistent color quality over time. • Produce consistent output across Fiery servers.
2 2-41 Understanding calibration The Fiery generates calibration curves after comparing measured values to the final target values for each of the four toner colors. The target values are based on the output profile specified. Measurements Measurement files contain numerical values that correspond to the toner density produced by the printer when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors. To create a measurement file, print a page of color patches.
2 2-42 Color Calibration Note: Because printed output from the printer is very sensitive to changes in temperature and humidity, the Sharp AR-C360P should not be installed near a window or in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate changes as well. It should be stored in a cool, dry, stable environment, and reams should remain sealed until they are needed.
2 2-43 Understanding calibration output profile were used, and when the printer was last calibrated: • Print a Configuration page or Test Page from the Control Panel or Command WorkStation/Command WorkStation LE. • Select a calibration set in Calibrator (available from ColorWise Pro Tools); the last calibration and the user who performed it are displayed.
2 2-44 Color Calibration Using Calibrator ColorWise Pro Tools Calibrator allows you to calibrate the Fiery using the measurement method of your choice. Changing the calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration.

3 3-68 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 3-69).
3 3-69 Profile Manager 3. Click the green arrow, choose a name and location for the profile, and click Save. The name will be the file name of the profile, but the profile description will be the original description, or the one you entered in the Profile Settings dialog box. Note: When saving the profile on a Windows computer, include the extension .icm. If the extension is not included, additional dialog boxes appear. 4. Click OK when you are notified that the profile was successfully uploaded.
3 3-70 ColorWise Pro Tools 1 through Source-10 for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output. For Windows computers, all profiles appear by their actual names in the printer driver. These fixed names are used in the printer driver, so you can select profiles per job even if your driver does not have the capability to obtain an updated list from the Fiery. Note: A custom simulation profile is used to illustrate this procedure.
3 3-71 Profile Manager 3. Select the “Appear in Driver as” option, choose one of the predefined custom simulation names (Simulation-1 through Simulation-10) from the menu, and then click Apply. Note: Choose a name that is not already linked with another simulation. You cannot define two profiles with the same name.

Use the sliders to adjust to the desired Dot Gain: • The range of values for North American at 50% input are from 0% to 50% gain on output. • The range of values for European at 40% input are from 0% to 59% gain on output; the range of values for European at 80% input are from 0% to 20% gain on output.
3 3-77 Color Editor A curve with this shape makes a color appear darker by adding density in the midtones. A curve with this shape makes a color appear lighter by reducing density in the midtones. A curve with this shape increases contrast. Note: Adjust points in this way only after you have entered the Dot Gain and Brightness values. For greater precision, type percentages in the Input and Output fields or use the arrow keys on the keyboard to adjust the curve.
3 3-78 ColorWise Pro Tools Note: Preset default profiles are locked and must be saved with a new name. For Mac OS computers, custom profiles must be linked to one of the ten predefined custom profile names (Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output) to be accessible from the printer driver. Create as many custom profiles as you want, but a maximum of ten are available from the printer driver at any one time.
3 3-79 Color Editor The edited simulation will be linked with the output profile you choose from the “Link with” menu. Note: When editing a simulation profile in Quick mode, clicking Import at the bottom of the Color Editor window allows you to import a custom Quick Simulation created on another Fiery using the previous version of ColorWise.

Spot-On allows you to adjust and manage lists of spot colors and their CMYK equivalents.
3 3-82 ColorWise Pro Tools 2. Choose the desired output profile and click OK. Output profile names appear here The Spot-On main window appears. The CMYK values you see in the window are calculated with respect to the specified profile. Using the Spot-On main window The Spot-On main window displays a list of color groups which represent libraries of spot colors on the Fiery. Tool icons for working with colors appear at the top of the window.
3 3-83 Using Spot-On By default, the Fiery includes several PANTONE libraries along with a System library. The DIC, HKS, and TOYO libraries are available with Spot-On. These factory default libraries appear marked with the default group icon ( ). You can also add custom color groups and colors to the Spot-On window (see page 3-85). Added groups appear marked with the custom group icon ( ). Both default and custom groups can be opened to display their included colors. To open and close a color group 1.
3 3-84 ColorWise Pro Tools Working with existing colors With Spot-On, you can view and manage existing groups of colors on the Fiery. You can also search for a particular color in the SpotOn list. Color groups in the Spot-On window appear in order of their priority. Highest priority is given to color groups at the top of the list. For instance, if two colors from two different color groups have the same name, the Fiery uses the color from the higher group and disregards the other color.
3 3-85 Using Spot-On name, and click OK. The pasted selection becomes a custom color group or color with the specified name. To find a specific color 1. Choose Find from the Edit menu. The Find dialog box appears. 2. Enter the name of the color you want to find and click OK. Spot-On searches for the specified color, starting from the top of the color list. The located color appears selected in the color list. 3.
3 3-86 ColorWise Pro Tools To rename a custom color or color group 1. Select the Color Name or specific color you want to edit. 2. Type the new name exactly as it appears in the print job documents, including uppercase and lowercase characters and spaces, as necessary. Note: Default groups or colors, such as PANTONE, cannot be renamed. Downloading custom color groups You can download custom color groups from your computer to the Fiery.
3 3-87 Using Spot-On The Select file dialog box appears. 3. Locate and select the desired color group, and click Open. The downloaded group is added to the specified location in the Spot-On list. If you did not specify a location, the group is added to the top of the list. If the downloaded group has the same name as an existing group in the list, you are prompted to rename the downloaded group.
3 3-88 ColorWise Pro Tools 2. Choose Upload from the File menu. The Save As dialog box appears. 3. Browse to the location where you want to save the file, name the file, and then click Save. Editing color values The Spot-On Color Search targets the exact CMYK toner equivalents required to simulate a desired spot color on the printer. If an existing spot color is not printing as desired, you can modify the color values as needed to achieve your intended result.
3 3-89 Using Spot-On The current color appears in the centerpatch of the window. 2. To update the centerpatch to a neighboring color that more closely matches the target, click the corresponding neighbor patch. Neighboring patches represent variations from the centerpatch and can be selected if they offer a closer match to the desired color. Clicking one of these patches updates the centerpatch to the new color and provides a new selection of neighboring colors.
3 3-90 ColorWise Pro Tools Select either Lightness or Saturation in the Color Directions Legend. Lightness generates neighbor patches based on darker to lighter shades of the original color. This variation is displayed from left to right, with the original color remaining in the centerof the middle group. Saturation generates neighbor patches based on less saturated to more saturated variations of the original color.
3 3-91 Using Spot-On For Paper Size, choose the size of the paper you want to use for printing the patches. For Paper Tray, specify the input tray for the paper you want to use. 6. Click OK to print the patches.
3 3-92 ColorWise Pro Tools 2. Select how you want to enter the CMYK values. The Percentages option allows you to enter color values between 0 and 100%, in increments of 0.5. Values out of this range are rounded to the nearest whole or half percentage. 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 Fiery can actually reproduce, and provides finer gradations of color than are possible with Percentages. 3.
3 3-93 Using Spot-On For best results, download and save any measurement data you have gathered with the ED-100 or ES-1000 in its offline state. Spot-On automatically clears stored data when it establishes a connection with the instrument. For information on downloading stored data from the ED-100 or ES-1000, see the documentation included with the instrument. To import color measurements into Spot-On 1. Install and set up the ES-1000 or ED-100 for use with your computer.

B B-109 Appendix B: Importing Density Measurements Importing Density Measurements This appendix describes Simple ASCII File Format, which can be used to import density measurements from measurement devices. To use your own measurement data from an alternate measurement instrument, record your individual readings in a text file and structure it as follows. Simple ASCII Import File Format (SAIFF) This format describes Status T measurement data for import into the ColorWise Pro Tools Calibrator.
B B-110 Importing Density Measurements For Windows computers, the file extension must be .cm1. For Mac OS computers, the file type must be ‘TEXT’. Measurement data in EFI 34 and EFI 21 are paper-relative. For other pages, if the first line corresponds to zero ink value, the Calibrator assumes that the measurement data is absolute and adjusts it to become paper-relative by subtracting the density values of the first line from the remaining patches.
B B-111 Importing Density Measurements Example of 1D Status T density for EFI 21 patch page This file format is used to specify the Status T density measurements of the EFI 21 patch page. The value in the first column is the patch number.
