Suggested Device Color Profile Name Operating Range Generic EBU 1.5 Gamma Monitor Gamma Range: 1.4 to 1.7 Generic EBU 1.8 Gamma Monitor Gamma Range: 1.7 to 2.0 Generic EBU 2.1 Gamma Monitor Gamma Range: 2.0 to 2.4 Generic P22 1.5 Gamma Monitor Gamma Range: 1.4 to 1.7 Generic P22 1.8 Gamma Monitor Gamma Range: 1.7 to 2.0 Generic P22 2.1 Gamma Monitor Gamma Range: 2.0 to 2.4 NEC B22 1.5 Gamma Monitor Gamma Range: 1.4 to 1.7 NEC B22 1.8 Gamma Monitor Gamma Range: 1.7 to 2.0 NEC B22 2.2 Gamma Monitor Gamma Range: 2.0 to 2.4 The DCPs are optimized for a monitor set to the matching gamma range through manual adjustment of the contrast and brightness knobs (if possible), or through a software utility, a hardware calibrator, or a hardware characterization device. If you are unsure of your monitorÕs phosphor type (for example, P22 or EBU), refer to the monitorÕs userÕs guide or contact the monitor manufacturer or dealer. If you are unable to determine phosphor type or gamma from these sources, display an image that is typical of the images you most often work with, and determine which PT produces the best contrast and color result as follows: 1. Select the Generic P22 1.8 Gamma Monitor DCP first and print the image. If color displays darker on the monitor than they appear when printed, use the Generic P22 2.1 Gamma Monitor DCP instead. Note: a higher gamma indicates a darker, higher contrast monitor. Therefore, the 2.1 Gamma monitor DCP yields lighter, flatter results (higher RGB values) because the monitor on which it is based is darker than a 1.8 Gamma monitor. 2. Once the optimal monitor gamma is achieved, check the screen match to the output, then select the EBU DCP with the matching gamma setting, and redisplay the image. For example, if the Generic P22 2.1 Gamma Monitor DCP gave you the best contrast, choose the Generic EBU 2.1 Gamma Monitor DCP. If your monitor has EBU-type phosphors, you will see an improvement in the monitorÕs simulation of the colors you achieve in print. Otherwise, switch back to the appropriate P22 DCP. NOTE: Be sure the Output Simulation function, when available with your color management application, is ON to best compare monitor-to print agreement. Effect of a Monitor Selection on Output Results When a Kodak CMS Output profile is used to convert from the monitor RGB to the output color space, selection of a different monitor will affect the screen display, but will not affect the output results. However, if a Kodak CMS output profile is not used, selection of an alternative monitor transform will change both the screen display and the output results. For example, with the Adobe Photoshop V2.5.1 ÒKodak CMS Photo CDÓ option in the Open As menu, it is possible to select a monitor space such as ÒAdobe Photoshop RGBÓ or ÒAdobe Photoshop CIELabÓ as the destination color space. Use of any of the 6 Òstarter packÓ monitor transforms as a destination color space will produce different results from the ÒAdobe Photoshop RGBÓ or the ÒAdobe Photoshop CIELabÓ color spaces. These 6 transforms are intended to compensate for phosphor set and gamma differences of the most popular monitor types, not necessarily for the results of using PhotoshopÕs Change Mode. Experiment with both visual match of the RGB file to the resulting output print, and the relative output quality delivered by the color table in use for PhotoshopÕs Change Mode, to pick the optimal destination color space. For example, using a 2.1 gamma monitor as the destination would lighten the picture display and consequently the output. Note: for the most accurate display of images, a colorimeter and associated software is recommended; call (800)75-COLOR for details. _________________________________________________________ When Using OUTPUT DCPs Output Precision Transforms are based on the state of the device as shipped by the vendor, with the selections of media and device settings as specified in the readme. The Proofer CMYK profiles assume a linear response from the film writer (e.g., a 50% screen generates a 50% dot on film), and assumes calibrated exposure settings on the proofing system. The linearization of printers should not be modified except where noted. Although manufacturing variations from unit to unit are possible, which cannot be compensated for in device profiles, color shifts are more likely to result from use of different media or device settings from those specified. _________________________________________________________ When Using Printer DCPs For the QMS ColorScript 100 model 30i Thermal Wax Printer: Color Configure Name: QMS ColorScript 100 Model 30/30i Description: These Precision Transforms convert between independent Reference Color Space (RCS) and QMS ColorScript 100 Model 30/30i Printer CMYK color space.

They are intended for use with a Kodak Coloredge 1550 (or Canon CLC500/550) color copier that has not been linearized with a 3rd party calibration package (e.g., EFI Calibrator or Southwest Software's Color Encore). This calibration is intended for use with the ColorQ print server system from Color Age, Inc, without Color Vantage calibration software; however, it can also be used on a copier driven by the Canon RIP, or the EFI Fiery RIP, or others, without linearization software. It may be advisable to adjust solid toner densities through the copier controls to achieve optimum results. Control Settings: Output Media: Hamermill Laser Print Output Colorants: Standard Kodak Coloredge 1550 toners Status T Maximum Densities: Cyan Magenta Yellow Black 1.42 1.11 0.94 1.54 _________________________________________________________ For the .Kodak Coloredge 1550 with Fiery RIP Calibration - with EFI Calibrator linearization: Color Configure Name: Kodak1550 (EFI Linear) Description: These Precision Transforms convert image data between independent Reference Color Space (RCS) and Kodak 1550 copier color space. They are intended for use with a Kodak Coloredge 1550 (or Canon CLC500/550) color copier that has been linearized with the EFI Calibrator calibration package. ÒLinear CMYK deviceÓ should be selected as the base profile, and then updated with actual density measurements. Control Settings: Colorant Laydown mode: contone (not halftone) Output Media: Hamermill Laser Print Output Colorants: Standard Kodak Coloredge 1550 toners Status T Maximum Densities: Cyan Magenta Yellow Black 1.01 1.58 1.25 1.30 _________________________________________________________ When Using SWOP Proofing DCPs These 2 device profiles are based on the same set of SWOP standard colorants and density aims, which are considered representative of standard industry proofing systems. For Coated stock, UCR and GCR are set at 320 and Light (30%), respectively, and the transforms are referred to as "SWOP Proofer CMYK - Coated Stock" in the Configure program. For Uncoated stock, UCR and GCR are set at 280 and Light, respectively, and the transforms are referred to as "SWOP Proofer CMYK - Uncoated Stock" in the Configure program. The inverse transform to convert from CMYK to RCS is identical for Coated and Uncoated. Black ink coverage - in general, a ÒskeletalÓ black aim curve is in effect to achieve a given color. While this still produces a moderate amount of black ink even on light GCR tables, often black is used to achieve the desired color; it is not necessarily present as an effect of UCR or GCR. Status T Maximum Densities: Cyan Magenta Yellow Black 1.3 1.4 1.0 1.7 GENERAL NOTE ON GENERIC CMYK OUTPUT DCPs: Output device profiles include the input format for an output device, which is used by some applications to display a CMYK picture more accurately. This inverse transform can also be used to translate a picture file that has been stored in the output color space, but this is not recommended for general use. The number of color transformations applied to an image should be minimized as much as possible, for both quality and productivity reasons. For instance, colors may be compressed into the gamut of an output color space, and may not be fully invertible back to the corrected RGB. It is advisable to keep the corrected RGB images as the source for subsequent outputs, because unnecessary transforms are avoided.
