1 EFI Color Tech Brief: The Magic of Black with Fiery Color Profiler Suite Introduction As digital press owners increase their expectations for color quality and want to validate printed output against industry standards, such as Fogra and ISO, they need guidance on how to achieve the best results with Fiery color tools and Fiery Color Profiler Suite. Toner-based digital print systems typically ship with default ICC profiles designed to optimize smoothness in light areas where tone reproduction has historically been better on conventional presses. However, in order to achieve better color accuracy and validate against ISO standards, correctly configuring the black and other profile settings is critical when creating output profiles and configuring Fiery color settings. This tech brief describes the best practices for configuring Fiery color settings and using Color Profiler Suite to make profiles that validate against industry standard such as Fogra and ISO. Applying high levels of gray-component replacement (GCR) is useful for achieving better grays, getting better precision to validate against ISO standards, and achieving expanded gamut on the output. Several competing color-profiling tools have been attracting customer attention in the market by promising better precision mostly using device link profiles (DLPs). However, none of these tools are as easy to use as tools that are integrated with a Fiery print server for both novice and expert users. Profiles made with Color Profiler Suite match Fogra standards with better image appearance than any of these competitors. Fiery Color Profiler Suite, at $3,400 MSRP for the full package with unlimited profiling, is the least costly and most efficient way for customers to achieve the desired color results and to match ISO standards in their ongoing print operations. Background To understand why additional training is necessary to achieve true black in an ICC profile that enables validation of printed output against ISO standards, it is important to review how users have traditionally generated black. Black generation in ICC profiles is modeled on how black separations were generated when making films using an analog process camera or a trade scanner. Historically, black was made as a camera black separation using a salmon-colored filter. The other color separations were captured with red, green and blue filters to generate CMY separations. These separations originally had full-range blacks with black halftone dots present throughout the tone scale, including in the highlights. With the advent of digital trade scanners for making separations and printing processes that did not require a dot to be present throughout the tone scale for proper press operation, black generation moved to the use of a skeletal black Electronics For Imaging, Inc.

2 In a skeletal black separation, black use is minimized in highlight regions so that it can be used to maximize contrast in the mid- to three-quarter-tones. The human eye is most critical of the light areas of an image and, for this reason, most of the contrast range of the three colors is used in these areas to maximize contrast. This results in the three colors becoming flat in the shadow regions. Black can then be used to restore contrast. Scanner color computers and some modern color separation techniques allow the optional use of under-color removal (UCR) and/or gray-component replacement (GCR). UCR reduces the amount of color ink (or toner) in neutral shadows. GCR uses black to replace color inks or toners in saturated colors to potentially minimize ink/toner consumption and to achieve better stability in the printing process. Color Profiler Suite Controls for the Black Channel Black channel control is the most important part of how color separations are made, whether the profile is for a digital or conventional press. Fiery Color Profiler Suite offers a full range of controls to shape the black separation channel and to enable special features such as UCR and GCR. Color Profiler Suite gives the user maximum control over black generation settings with more sophisticated tools than competing profiling solutions developed originally for the offset market. Color Profiler Suite can make excellent profiles for conventional printing systems, but also has refined tools for specific toner engine behaviors. No competing solution offers as wide a range of black generation controls as Color Profiler Suite. How to Optimize Black Generation in Color Profiler Suite Profiles The Fiery Calibrator Wizard, available in Fiery System 10 and later, is designed for novices to easily make high-quality profiles by accessing Color Profiler Suite directly from Fiery Calibrator. However, to access and configure the expert black controls, users need to make a profile with optimized black settings. For this, use the Printer Profiler feature in the full version of Color Profiler Suite rather than the calibration wizard. Refer to the diagram on page 5 for general steps required to create color profiles used for certification. Before making a custom profile in Color Profiler Suite, users should create a custom Calibration Set for the paper to be profiled. To begin this process, start with the procedure for the specific Fiery software version as shown here: For Fiery System 10 and later, follow the steps in Appendix A. For Fiery System 9 Release 2 and older, follow the steps in Appendix B. Then follow the steps in Appendix C for all Fiery systems to create a custom ICC output profile without a calibration target, and to add the calibration target when importing the profile to the Fiery print server Electronics For Imaging, Inc. 2

3 Optimizing Color Matching with a Device Link Profile In general, the color management tools that compete with Color Profiler Suite require users to create device link profiles (DLPs) to validate against ISO standards. This is a more time-consuming technique that requires multiple measurements and iterated refinements of the DLP. However, EFI technology does not require users to create a DLP to match and certify against any standard. EFI has a large number of Fogra certifications and more IDEAlliance digital press certification than any digital front end in the world, all achieved only with Fiery Color Profiler Suite without using DLPs. Color Profiler Suite does offer similar DLP tools and some additional functions in the Device Linker for matching G7 tolerances, but DLP s are typically not required for any validation. Users who want to achieve closer colorimetric matching to an appearance standard such as ISO Coated Fogra 39 or G7 tonality and gray balance may choose to use the Color Profiler Suite Device Linker. If a DLP is required, Color Profiler Suite simplifies the creation process since users can create and update the device link profiles directly on the Fiery print server. This means users do not need to change color settings for jobs that use these profiles as the DLPs are updated. By comparison, it is complicated, time consuming and easy to make mistakes when creating and using DLPs from third-party tools and workflows because users must manually edit Job Properties so that legacy jobs can leverage updated DLPs. See Appendix D for how to make a DLP with Color Profiler Suite and use it on a Fiery print server. Comparisons with Competitive Products Consider these aspects of competing color management tools when evaluating their use for profiling the Fiery print server and validating against ISO standards: Competing tools have no expert knowledge built into them about how various toners or inks combine on specific print engines leaving the user to guess how the colorants will combine on a particular printer and how to configure black settings to accommodate this. Color Profiler Suite allows users to load a factory profile that EFI experts have optimized for the particular printer. Using these profiles eliminates the guesswork by providing an easy starting point to create a custom profile for a particular media. Competing color management tools are not integrated with the Fiery print server, so the user must be trained to manually print patch sets correctly, load custom profiles and keep track of jobs and workflows that use each profile over time. Using Color Profiler Suite saves time, confusion and errors in the profiling process. Competitive tools are either very costly (U.S. $10,000 and up) or are priced based on toner savings which the software itself calculates, instead of using a true measurement. Manufacturers have no independent, verifiable way to predict the long-term cost or value of the solution and, for this reason, business models based on toner savings are likely not viable. Unlike competitive tools that rely on DLPs, EFI does not require users to create a DLP to match and certify against any world standards. EFI Fiery print servers have achieved a large number of Fogra and IDEAlliance certifications with a simple output profile created from Color Profiler Suite Printer Profiler. For details, please review the Application Data Sheet (ADS) for print systems certified by IDEAlliance at Electronics For Imaging, Inc. 3

4 Summary Using Fiery Color Profiler Suite is the least costly and most efficient way for customers to achieve desired color results and match industry standards, such as ISO, in their ongoing print operations. Color Profiler Suite is bundled with many production-level Fiery print systems, so customers do not need to invest in additional color-matching tools. Color Profiler Suite Maximum GCR profiles deliver better print appearance than competitive products. Fiery partners and dealers find that it is more profitable to deliver an integrated and bundled color management solution, leveraging partner professional services or EFI Tier-1 support, and sell a loyal customer more print systems over time. Trying to up-sell the customer an expensive alternative to Color Profiler Suite has the risk that the customer will fail to achieve the desired color results over time and choose another vendor for their next press purchase. In real-world printing operations, color management is still not one-button easy. However, Color Profiler Suite integrated to Fiery servers and combined with EFI Fiery Global University training, how-to documents, read-me files, Fiery Forum feedback, Fiery Dashboard, and bundled EFI Tier-1 tech support provides the product experience and instructions necessary to create and maintain custom printer profiles and verify color precision against ISO standards Electronics For Imaging, Inc. 4

5 Matching Industry Color Standards with Color Profiler Suite This diagram provides an overview of the steps required to create custom calibration sets and output profiles on various Fiery systems. Fiery System 10 and later See Appendix A for step by step instructions. Create new calibration set via the wizard. Use Fiery Calibrator. Follow steps 1 to 18 of the wizard on the Fiery server before exiting. When saving a calibration set, a duplicate output proflle will be created that may be used to select the new calibration set. Exit the calibration wizard at this point. Do NOT allow the wizard to create an output profile at this point or you will not have access to the profile settings. Fiery System 9 Release 2 and older See Appendix B for step by step instructions. Create new calibration set. Use Fiery Calibrator. Choose an exiting calibration set as a starting point and an ouput proifle which will be duplicated to create a placeholder profile that can be used to select the new calibration set. Record Dmax values. In Calibrator, record the measured values, not the target values. Apply and save new calibration set. Enter the Dmax values from Calibrator into the temporary output profile that includes the name of the calibration set just saved. Apply and save the profile. See Appendix C for step by step instructions. Load the temporary output profile linked to the the custom calibration set as the server default. Disable the option Use Media Defined Profiles if available in expert color settings, to ensure that the temporary profile remains selected when printing. Create a custom output profile in Color Profiler Suite Printer Profiler with Use Current Calibration in Color Profiler Suite if the option is offered when starting. For Profile settings, choose a factory default profile for a paper similar to the one being profiled. Choose Optimize Colorimetric Precision and Maximum GCR options. Create a new output profile with custom black settings and when saving, link it to the new calibration set. Configure color settings on the Fiery server to use the new profile. Optional: Use Color Profiler Suite Verify module for verification. Procedures for verification are at help.efi.com/cps in the User Guide. Optional: See Appendix D to create a device link to achieve precise colorimetric matching Electronics For Imaging, Inc. 5

To start, launch Fiery Command WorkStation and connect to the Fiery print server. 2. Go to Device Center > Color Setup. 3. Click on Basic Settings in the Color Setup tab. a. Set CMYK Source to ISO Coated FOGRA39L to match Fogra 39 standard for Europe or Asia, or SWOP2006 to match IDEAlliance ISO standard in the U.S. b. Set the CMYK processing method to Full (output GCR). c. For Gray and Black, set the CMYK gray setting to Off to disable special black preservation for images. This setting must be disabled in order to pass certifications. d. Set the Output Profile to the custom ICC profile just created in Color Profiler Suite. e. Check to see that the calibration set loads with the custom profile. f. Click the Expert Settings button at the upper right of the Basic Color Settings window Electronics For Imaging, Inc. 24

25 Appendix - C. Configuring Fiery Color Settings g. For a verification print using a standard control bar, enable Simulate Paper White on expert color settings. This will allow that job in Job Center to match an appearance-matching stan dard such as ISO Coated v.2 if the white point of paper profiled does not have the same white point as the standard. This option is only available with Fiery Graphic Arts Package, Premium Edition installed on the Fiery server. Note: Enabling Simulate Paper White will result in a print that has dots in the non-image paper white areas if the paper being profiled does not have the same white point as the standard to be matched. While such a print may measure successfully for certification, customers will be more satisfied with production print jobs that use a paper with the same white point as the standard, thereby avoiding the paper simulation dots. Another option is to loosen the tolerance for paper white matching in the verification software. h. Go to the Output tab and make sure Use media-defined profiles if available is disabled. Otherwise, the media-defined profile for the paper type will be used instead of the new custom profile selected in Step D above. i. Save the server defaults by clicking OK Electronics For Imaging, Inc. 25

26 Appendix - D. Make a Device Link Profile Make a Device Link Profile with Color Profiler Suite To make a DLP with Color Profiler Suite and use it on a Fiery print server is easy. 1. Launch Device Link from the Color Profiler Suite launch pad and choose Optimize a device link. 2. Click Next and select the Fiery print server. Set the source profile to the profile for the desired industry standard to be matched (such as ISO Coated v2), then set the destination profile to the custom profile created using the procedures described above and click Next. 3. Set the Rendering Intent to Relative Colorimetric and use default Separation Options. To use a paper white simulation when the paper profiled does not match the white point of the standard, choose the Absolute Colorimetric setting instead. Remember, this means there will be printed dots in non-image areas, and may not meet appearance standards of production print buyers. Making the DLP with the Relative Colorimetric setting will eliminate this problem Electronics For Imaging, Inc. 26

27 Appendix - D. Make a Device Link Profile 4. Click Next. Choose the instrument, patch layout and paper size. The 928 patch target is often precise enough for DLP iteration. 5. Click Next. Now print, measure and optimize until Es are acceptable. Remember to keep resolution and halftone screen settings the same for every iteration print. 6. The last step is to save this new DLP, set it as the server default and attempt verification again Electronics For Imaging, Inc. 27
