Introduction

As it pertains to general desktop use, an ICC profile is a binary file which contains precise data regarding the color attributes of an input, or output device. [1] Single, or multiple profiles can be applied across a system and its devices to produce consistent and repeatable results for graphic and document editing and publishing. ICC profiles are typically calibrated with a (tristimulus) colorimeter, or a spectrophotometer when absolute color accuracy is required.

ICC Profile Generation

OS File Transfer

Profile generation on a Windows 7/Vista/XP, or Mac OS X system is one of the easiest and most widely recommended methods to obtain a ICC monitor profile. Since ICC color profiles are written to an open specification, they are compatible across operating systems. Transferring profiles from one OS to another can be used as a workaround for the lack of support for certain spectrophotometers, or colorimeters under Linux: one can simply produce a profile on a different OS and then use it in a Linux workflow. 2 Recommended colorimeters include the X-Rite i1Display 2 and the Spyder3 Pro. Note that the system on which the profile is generated must host the exact same video card and monitor for which the profile is to be used. Once generation of an ICC profile, or a series of profiles is complete on a Windows 7/Vista/XP system, copy the file(s) from the default path:

C:\WINDOWS\system32\spool\drivers\color

Mac OS X generally stores saved ICC profiles in one of two locations:

/Library/ColorSync/Profiles
/Users/<username>/Library/ColorSync/Profile

Once the appropriate .icc files have been copied, install the device profiles to your desired system. Common installation device profiles directories on Linux include:

/usr/share/color/icc
/usr/local/share/color/icc
Note: Ensure that the calibrated contrast, brightness and RGB settings of the monitor do not change between the time of calibration and the loading of the ICC profile.

Loading ICC Profiles

xcalib

Xinitrc Example

Load profile Template:Filename in /usr/share/color/icc/ on display host:0 when X server starts

#!/bin/bash

/usr/bin/xcalib -d :0 /usr/share/color/icc/P221W-sRGB.icc

JWM Template:Filename Example

Load profile Template:Filename in /usr/local/share/color/icc/ on display host:0 when JWM starts

 <StartupCommand>xcalib -d :0 /usr/share/color/icc/P221W-sRGB.icc</StartupCommand>

dispwin

Xinitrc Example

Load profile Template:Filename in /usr/share/color/icc/ on display 0 when X server starts

#!/bin/bash

/usr/bin/dispwin -d0 /usr/local/share/color/icc/906w-Native.icc

JWM Template:Filename Example

Load Argyll calibration file Template:Filename in /usr/local/share/color/icc/ on display 1 when JWM starts

 <StartupCommand>dispwin -d1 /usr/local/share/color/icc/906w-Native.cal</StartupCommand>
