For the Hewlett-Packard ScanJet IIC w/ Twain Driver Interface
Color Configure Name: Hewlett Packard ScanJet IIC
Description: These Precision Transforms convert image data between RGB color space of the scanner and Reference Color Space (RCS). The PT contained in this DCP cannot be used independently; it must be composed, using color management software with a PT from another DCP, to form complete system-specific transforms.
Control Settings:
Contrast and Brightness should both be set to 125, and automatic range detection should be turned off.
Description: These Precision Transforms convert image data between RGB color space of the scanner and Reference Color Space (RCS). The PT contained in this DCP cannot be used independently; it must be composed, using color management software with a PT from another DCP, to form complete system-specific transforms.
Control Settings:
Contrast and Brightness should both be set to 0, and automatic range detection should be turned off.
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.
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.
Control Settings:
Output Media: Hamermill Laser Print
Output Colorants: Standard Kodak Coloredge 1550 toners
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. "Linear CMYK device" 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
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.

GENERAL NOTE FOR ALL CMYK PROOFING 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.
