-
- When Using Monitor DCPs
-
- The following table gives the suggested gamma operating range for
- each monitor DCP.
- 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 monitor╒s phosphor type (for example, P22
- or EBU), refer to the monitor╒s user╒s 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 monitor╒s 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 ╥Kodak CMS Photo CD╙ option in the Open As menu, it is
- possible to select a monitor space such as ╥Adobe Photoshop RGB╙ or
- ╥Adobe Photoshop CIELab╙ as the destination color space.
-
- Use of any of the 6 ╥starter pack╙ monitor transforms as a destination
- color space will produce different results from the ╥Adobe Photoshop
- RGB╙ or the ╥Adobe Photoshop CIELab╙ 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 Photoshop╒s 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 Photoshop╒s 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.

-
- For the Kodak Coloredge 1550 Copier
- ╨without linearization software:
-
- Color Configure Name: Kodak 1550 Color Copier w/ ColorQ Server
-
- 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 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.

-
- 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. ╥Linear CMYK
- device╙ should be selected as the base profile, and then updated with
- actual density measurements.
-

- 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 ╥skeletal╙ 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.
