Specific features and options may vary, depending on the Color Server model at your site. N OTE : The term "printer" is used throughout this manual to denote a supported printer or copier; the term "toner" refers to either toner or ink. About this manual This manual provides an overview of general color concepts, with a specific focus on color management for print output. It describes multiple scenarios (called workflows) during which color information can be specified. It also provides application notes that explain how to print to the Color Server from popular Microsoft Windows and Apple Mac OS applications. Color terms and concepts, such as "color space," "spot color," "gamut," and "source profile" appear in bold throughout this manual. If you are new to desktop color, or if any terms are unfamiliar, see Glossary, which is a separate document in this set. INTRODUCTION 8 For additional information This manual is one in a set of documentation that includes manuals for both users and system administrators. For a description of all the available documentation, see Welcome. All other manuals should be available at your site. Refer to them for more information as directed in this manual. For additional information about the topics discussed in this manual, see: · Color Printing: For detailed information about the color printing options and settings available with your Color Server, as well as the ColorWise® color management system built into your Color Server. · Print Options: For information about how to set the ColorWise print options. For information about performing color management tasks and using ColorWise Pro ToolsTM, see ColorWise Pro Tools Help. For general information about printing in color, see "Desktop Color Primer" on page 73 and the sources in the "Bibliography" on page 89. OVERVIEW OF COLOR MANAGEMENT CONCEPTS 9 OVERVIEW OF COLOR MANAGEMENT CONCEPTS To create successful color documents and presentations, you can take advantage of the features of color management software as they are implemented by the Color Server and on your desktop computer. This chapter is devoted to various elements of color management that contribute to predictable color results. Understanding color management systems A color management system (CMS) is a "translator" between the color space of the source device (for example, the monitor or a scanner) and the color space of the destination device (for example, the printer). It compares the color space in which the source image was created to the color space in which the job will be output, and adjusts the colors in the document to maintain consistency across different devices. A CMS typically uses a device-independent color space, such as CIELAB, as its intermediate color space. To perform its translation, a CMS needs information about the color space of the source image and the gamut of the printer. This information is provided through profiles, often created by the makers of the computer monitor or printer. The end product of a CMS conversion is a printed document or an image file in the gamut of a particular printer. There has been progress toward standardization in the field of digital color management systems. Both the Windows and Mac OS operating systems support an industry standard format developed by the International Color Consortium (ICC). This ICC format is implemented on Windows computers and on Mac OS computers. Other software developers are also incorporating color management systems into high-end applications. The Color Server color management system, ColorWise, supports this standard profile format. OVERVIEW OF COLOR MANAGEMENT CONCEPTS 10 How color management works Before you can print a color document, the color data in it must be converted to the gamut of the printer. Whether performed by the Color Server or a host-based CMS, the process of converting color data for a printer 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 output profile, also called a destination profile by some color management systems. Color management system Source profile Output profile Device-independent color space Input data Printed data or file The source profile defines the RGB color space of the image's source: characteristics such as the white point, gamma, and the type of phosphors used. The output profile defines the gamut of an output device, such as a printer. The Color Server (or the host-based CMS) uses a device-independent color space to translate between the source color space and the color space of the output device. The Color Server allows you to specify default and override settings for the source color space information and the output profile information (see Color Printing). When you use these settings, there is no need to use the features of other color management systems. Your Color Server software includes ICC profiles for use with other color management systems, although conflicts may arise when the Color Server CMS is used in conjunction with a host CMS. You can also use color management systems to adjust color data to the gamut of an output device other than the one to which you are printing. This process of simulating another output device is commonly used for proofing jobs that are printed on an offset press. For more information about the Color Server simulation feature, see Color Printing. The type of print job and the final output device, Color Server or offset press, determines the workflow that provides the best results. For information about choosing workflows, see "Using Color Management Workflows" on page 13. OVERVIEW OF COLOR MANAGEMENT CONCEPTS 11 Using ColorWise and application color management The Color Server color management system, ColorWise is designed to provide both casual and expert users the best color output for a variety of purposes. Several applications also provide their own color management system. This manual describes how to optimize print output using both ColorWise color management and application color management. The Color Server can intelligently manage the printed appearance of RGB, CMYK, and spot colors. You can allow the Color Server to manage color for most color printing jobs without adjusting any settings. A desktop (host-based) color management system uses ICC profiles to convert colors from one device gamut to another (see "Desktop Color Primer" on page 73). The color data is converted when it passes from one application to another or when the job is sent to the printer; thus, the processing occurs on your computer, as opposed to the Color Server. Conventional color management systems typically address only color conversions, and they occupy your computer processor. When you use ColorWise, jobs leave your computer and are processed faster on the Color Server. The advantages to ColorWise color management versus desktop (application) color management include the following: · Relieving your computer from performing additional processing. Delaying color conversions until the color data reaches the Color Server frees your computer so that you can continue working, and color conversions on the Color Server are, in most cases, much faster than similar conversions on a host computer. · Eliminating the potential for undesirable color management-related conflicts, such as iterative color conversions and inconsistent color. The Color Server applies global corrections to specific groups of RGB, CMYK, and spot colors to avoid such conflicts. · Accepting RGB files in addition to larger CMYK files from applications, which minimizes network traffic and enables jobs to print faster. ColorWise uses ICC profiles to convert colors to the device gamut or simulate other devices, such as an offset printing press. ColorWise manages color conversions for all users printing to the Color Server from Windows and Mac OS computers. It allows users to follow a simple workflow with minimal intervention using robust default settings, while giving advanced users the control and precision they need. OVERVIEW OF COLOR MANAGEMENT CONCEPTS 12 Using ColorWise color management tools Your Color Server user software includes several types of color reference pages that allow you to see the range of colors that can be printed on your printer. For predictable color, use the color reference pages when defining the colors in your document. The resources available are as follows: RGB Color Reference: A Microsoft Word file and a Microsoft PowerPoint file that allow you to view the colors available in the standard palettes of office applications and to see how those colors print on the Color Server (see "Using color matching tools with office applications" on page 21). CMYK Color Reference: An 11-page downloadable PostScript file of CMYK color patches (see "Using the CMYK Color Reference" on page 25). Process Simulation of PANTONE Sol ...
