1-2 iR C2100/2100S Color Management iR C2100/2100S color management generates CMYK data to be sent to the copier/printer; additional processing may then be performed before printing begins. The diagram below illustrates the print options in the iR C2100/2100S color management process that affect color data conversions. You access these print options when you send a print job to the iR C2100/2100S.
Page 19
1-3 Managing color on the iR C2100/2100S Settings for the following options can be specified via print options when you send a job to the iR C2100/2100S. Some can also be set as defaults by the administrator during iR C2100/2100S Setup. Settings specified via print options override the defaults.
1-4 iR C2100/2100S Color Management iR C2100/2100S color print option: What it does: CMYK Simulation Method Quick simulation applies one-dimensional transfer curves that adjust Quick/Full output density only. Full simulation applies colorimetric (Default set at Setup or in transformations that adjust hue as well as output density (see page 1-8). ColorWise Pro Tools) Output Profile The Output Profile is applied to all data in the print job (see page 1-9).
1-5 Managing color on the iR C2100/2100S Equivalent iR C2100/2100S rendering style: Best used for: ICC rendering style: —Creates saturated colors Artwork and graphs in presentations. Presentation Saturation but does not match printed colors In many cases it can be used for mixed Graphics precisely to displayed colors.
1-6 iR C2100/2100S Color Management • specifies an EFI-defined color space recommended for users who EFIRGB have no detailed information about their RGB data. • specifies the industry standard definition for a generic Windows sRGB (PC) PC monitor. • specifies the definition of all standard Mac OS computer Apple Standard monitors.
1-7 Managing color on the iR C2100/2100S The two choices available for this option determine whether RGB data is converted into the full gamut of the copier/printer (Output) or whether it is first converted into the gamut of another digital printer or a press standard (Simulation).
1-8 iR C2100/2100S Color Management If you are printing with the PostScript printer driver on a Windows 95/98 computer, the name of each profile is visible in the pop-up menu for the CMYK Simulation Profile setting. If you are printing with the PostScript printer driver on Windows NT, Windows 2000, or a Mac OS computer, custom simulations appear as Simulation 1 through Simulation 10.
1-9 Managing color on the iR C2100/2100S Output Profile The output profile is applied to all data in the print job, so make sure the selected profile is right for your job. The default output profile consists of both a profile for your copier/printer, describing its color characteristics, and a calibration target that describes the expected behavior of the copier/printer.
1-10 iR C2100/2100S Color Management The Pure Black Text/Graphics option can be used only when printing composites, not when printing separations. Pure Black Text/Graphics: Input black color: Prints 100% black With the default profile, prints a rich black using all toners. CMYK Prints only with black toner, because CMYK simulations preserve the black channel.
1-11 Managing color on the iR C2100/2100S PostScript applications may perform their own black overprint conversions before sending the print job to the iR C2100/2100S. One example of how you might use this setting is with a page that contains some black text on a light blue background.
1-12 iR C2100/2100S Color Management Spot Color Matching and the PANTONE Coated Color Reference The PANTONE Coated Color Reference (described on page 5-6) prints differently depending on the Spot Color Matching setting. • —The iR C2100/2100S uses its built-in table to generate the best matches of the PANTONE colors that your copier/printer can produce.
1-13 Printer Drivers and Print Options Your iR C2100/2100S user software includes Adobe PostScript printer drivers for Windows 95/98, Windows NT 4.0, and Mac OS computers or Microsoft PostScript printer driver for Windows 2000. These are the recommended printer drivers for printing to the iR C2100/2100S. (See Getting Started for information on installing printer drivers.)

2-1 Workflow concepts This chapter discusses color management workflows used in short-run color Chapter 2: printing as well as color proofing on the iR C2100/2100S. It also gives Simple and examples of color management in specific desktop applications and the Advanced interaction between those applications and ColorWise color management.
2-2 Simple and Advanced Workflows RGB, CMYK, and PANTONE colors Colors can be defined in several different color models, the most common being RGB, CMYK, and the PANTONE color matching system. Each model requires a different color conversion at the iR C2100/2100S. These different color conversion workflows are explained below.
2-3 Simple workflows One advantage of using ColorWise color management over desktop color management is that your computer is spared the added processing chores; delaying color conversions until the color data reaches the iR C2100/2100S frees up your computer so you can continue working, and color conversions on the iR C2100/2100S are in most cases much faster than similar conver- sions on a host computer.
2-4 Simple and Advanced Workflows Select your colors wisely For the colors you see on your monitor to match those on your printed output, they must go through color management, including precise calibration of your monitor and copier/printer. If you are not equipped or inclined to maintain accurate monitor color management, you may opt for an easier approach.
Page 43
2-5 Simple workflows CMYK Simulation set to None is also useful when you want to prepare an output profile of your calibrated copier/printer or when you use less efficient color management from the desktop (such as ColorSync or ICM). In this workflow, colors are modified only at the calibration stage. This is indicated by the black box in the diagram below.
Page 44
2-6 Simple and Advanced Workflows The iR C2100/2100S comes into play near the end of the color workflow. To ensure that the colors you have selected reach the iR C2100/2100S and ColorWise in a usable form, you should bypass any color management from applications and printer drivers.
2-7 Advanced workflows Turn off color management in your application Generally, when printing to the iR C2100/2100S, it is best to disable color management in the application to ensure that the iR C2100/2100S receives color data properly and prints it accurately. Save your files using color-safe settings There are several additional steps you can take to ensure color accuracy.
2-8 Simple and Advanced Workflows Short-run printing examples The following examples illustrate short-run printing on the iR C2100/ 2100S. Photoshop RGB workflow This short-run workflow of printing an RGB image from Photoshop is one of the simplest iR C2100/2100S color workflows. In it, RGB data is sent from the application, through the printer driver, to the iR C2100/2100S, and the RGB-to-CMYK conversion takes place on the iR C2100/2100S using a CRD rather than in the application.

3-1 Introduction Calibrating the iR C2100/2100S ensures consistent, reliable color output. Chapter 3: You can calibrate the iR C2100/2100S with ColorWise Pro Tools using an Color Calibration X-Rite DTP32 automatic scanning densitometer (available as an option). By connecting the densitometer to the serial port on your computer, you can quickly measure color patches and download measurements to the iR C2100/2100S.
3-2 Color Calibration • A calibration target that describes the expected behavior of the copier/printer is contained in each output profile. Once you have calibrated the iR C2100/2100S, a calibration set is stored on the iR C2100/2100S. This calibration set will be used when it is associated with an output profile.
Page 57
3-3 Understanding calibration Even with a calibrated system, toner density is affected by service settings, humidity, and temperature; it also tends to drift over time. Regular measurement detects day-to-day variations in densities, and calibration corrects for them. Calibration works by creating calibration curves on the iR C2100/2100S that compensate for the difference between actual (measured) and desired (target) density values.
3-4 Color Calibration Scheduling calibration In general, you should calibrate the iR C2100/2100S at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the copier/printer is subject to wide fluctuations in temperature or humidity, calibrate every few hours.
3-5 Using a densitometer Using a densitometer ColorWise Pro Tools are designed to work with the X-Rite DTP32 reflection densitometer where color measurements are entered automatically. When you cannot obtain an expected result with ReaderCal, use this procedure. Measurements from other densitometers can be input using a simple ASCII file format (see page C-1).
Page 60
3-6 Color Calibration 3. Attach the connector to the computer. For a Windows computer, insert the 8-pin mini-DIN end of the interface cable into the 9-pin DB9 Connector cable adapter. Insert the 9-pin end into the COM1 or COM2 port on the computer and tighten the screws. If the available port on your computer is 25-pin, you must use the 8-pin-to-25-pin adapter.
3-7 Calibrating the densitometer 4. Use the AC adapter to provide power. Plug the small connector on the adapter cable into the side of the X-Rite DTP32 and plug the adapter into a wall outlet. Small connector AC adapter 5. Turn on the computer. 6.

5-2 Working with Color in Applications • For color proofing, use an application that writes its own PostScript and define colors in RGB, CMYK, or choose colors from the application’s PANTONE color library. Placed images can also be defined in RGB or CMYK.
5-3 Office applications Office applications The iR C2100/2100S must receive PostScript instructions to print an image or a document. Many applications do not create these PostScript instructions by themselves, and instead rely on the printer driver to create them. Included in this category are most word processors, spreadsheets, and presentation packages.
5-4 Working with Color in Applications Choosing colors in office applications Two RGB color reference pages, a Microsoft Word file and a Microsoft PowerPoint file, are provided with your iR C2100/2100S user software. Print these files using different CRDs to see how the colors appear when printed to the iR C2100/2100S.
5-5 PostScript applications Generally, PostScript applications send color information to the iR C2100/ 2100S as CMYK data. An exception to this is an RGB image placed in the document, which is sent directly to the iR C2100/2100S (unless you specify special color management settings in the application).

7-8 Adobe Photoshop If you experience problems printing the document in which you place the image, substitute an ASCII 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.
7-9 Photoshop 5.x Selecting options when printing You can print RGB or CMYK images from Photoshop. • When you print an RGB image, you can choose whether the conversion to CMYK is performed by the iR C2100/2100S (using a CRD), by PostScript (using PostScript Color Management), or by Photoshop's built- in color management engine (by choosing an Output profile from the Space menu).
7-10 Adobe Photoshop Printing CMYK images Use the following instructions to print CMYK images. Choose an encoding Choose CMYK method Color as the color space Choose CMYK Color from the Space pop-up menu. Any other setting causes Photoshop to convert image data to that color space before sending it to the iR C2100/2100S.

7-11 Photoshop 5.x For fastest print times, choose JPEG encoding, but check printed output carefully for unwanted artifacts that can appear as a result of JPEG compression. If you see unexpected results in the printed output, print the job again using Binary or ASCII encoding. Choose other print options you want to use (see Chapter 1).
7-12 Adobe Photoshop Photoshop 4.x A special feature of Photoshop allows you to save RGB EPS (PostScript) images that include independent source color space information. This feature is sometimes referred to as “PostScript Level 2 tagging” or “RGB tagging.” You define the source color space to apply to RGB EPS images by specifying a Monitor Setup in Photoshop.

A-2 Desktop Color Primer 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, a way of defining colors in mathematical terms, to help...
A-3 Desktop Color Primer 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 simulate the range of visible colors using a set of primary colors that are combined to create other colors.
A-4 Desktop Color Primer The subtractive primaries are cyan, magenta, and yellow; they absorb red, green, 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.
A-5 Desktop Color Primer 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 and allows you 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.
A-6 Desktop Color Primer Even if your color printing is done exclusively on the iR C2100/2100S, 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.
A-7 Desktop Color Primer 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.
A-8 Desktop Color Primer Color text can add flair to documents printed on paper when used skillfully. This technique 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.
A-9 Desktop Color Primer When printing raster artwork, the quality of the output depends on the resolution of the source raster. If the raster resolution is too low, individual pixels become visible in the printed output as small squares. This effect is sometimes called “pixelation.”...

A-10 Desktop Color Primer 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...
A-11 Desktop Color Primer 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. Image quality 100 ppi 200 ppi 300 ppi...
B-1 Color Management This appendix provides information on controlling and managing color Appendix B: output in order to achieve predictable color results. It also discusses the basics Color of color management. Management 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.
B-2 Color Management Paper stock and toner The paper and toner used by your copier/printer can greatly affect printed color. For best results, use the supplies recommended by the manufacturer of the copier/printer. Maintenance Problems such as streaking and insufficient or excessive amounts of one or more toners arise when a copier/printer does not receive periodic maintenance or needs major repairs.
B-3 Color Management 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 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 gamut requirements of a print device.
B-4 Color Management Color conversion Before a color document can be printed, the color data in it must be converted to the gamut of the print device. Whether performed by the iR C2100/2100S or by a host-based 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 output profile, also called a destination profile by...
