When you install many Adobe programs, the Adobe gamma software also gets installed on PCs.
Deactivating Adobe gamma
You can use it to calibrate your monitor at the system level and to create an ICC profile that describes how your particular monitor reproduces colour. Any application that uses ICC profiles can use this profile.
Although we only use Macs at Northlight, we get asked about this often enough that we've included this short guide to deactivating Adobe Gamma on your PC
Why turn off Adobe Gamma?
If you are going to calibrate your monitor, then it's best that only one piece of software does the job for you.
Adobe gamma is a useful bit of software that gets installed that can help you set up your monitor to look better.
Remember that adjusting a monitor by eye is at best a partial solution (see our viewing guide for more info about adjustments 'by eye')
If you are going to use any of the popular profiling packages (by ColorVision/X-Rite/Pantone for example) on a PC then they all recommend disabling Adobe Gamma
Turning off the automatic start-up of Adobe Gamma
Adobe Gamma is usually started by a short-cut in the start-up items folder. You can just delete this and the software won't get automatically started.
Note - If there is no short-cut there, then Adobe Gamma isn't getting loaded, so just carry on and use your profiling package
The installer installs the Adobe Gamma control panel (Adobe Gamma.cpl) into the Windows/System folder (Windows Me and 98) or the Program Files/Common Files/Adobe/Calibration (Windows XP and 2000), and it installs the Adobe Gamma loader application (Adobe Gamma Loader.exe) into the Program Files/Common Files/Adobe/Calibration folder. In addition, it installs a short-cut to the Adobe Gamma Loader application in the Windows/Start Menu/Programs/Startup folder (Windows Me and 98) or the Documents and Settings/All Users/Start Menu/Programs/Setup (Windows XP and 2000). As a result, the Adobe Gamma loader application appears in the Start > Programs > Startup menu and starts automatically during Windows startup.
While loading Adobe Gamma.cpl during Windows start-up, the Adobe Gamma Loader application applies settings in the Adobe Gamma.cpl file to the system and applies calibration settings for your monitor at the system level.
It's found at Drive/Documents & Settings/All Users/Start Menu/Programs/Start Up/Adobe Gamma Loader (alias)
The easy way to get at it is:
- right-click on the Start button
- go to Open or Open All Users
- double-click PROGRAMS
- double-click STARTUP.
- Right-click on Adobe Gamma or Adobe Gamma Loader and delete.
Your profiling software will often place a new short-cut in the startup items folder that activates your new profile
Any Adobe Gamma alias is in the same place as above - just delete it
Windows Me and 98
- Choose Start > Settings > Taskbar and Start Menu Properties (Windows Me), or choose Start > Settings > Taskbar (Windows 98).
- Click the Advanced tab (Windows Me) or the Start Menu Programs tab (Windows 98).
- Click Remove in the Customize Start Menu section (Windows 98), or click Remove in the Start menu section (Windows Me).
- Double-click Programs if it isn't expanded, and then double-click StartUp.
- Select Adobe Gamma Loader.exe, and click Remove.
- Click Yes if asked if you want to remove this item (Windows 98).
- Click Close in the Remove Shortcuts/Folders dialogue box, and then Click OK in the Taskbar Properties dialogue box.
If you are curious about colour management and what it can do for you, then we have a growing collection of reviews and articles about software and hardware, and how to use it.

- CMYK for photographers (2) - Press management
An overview of colour management for when your work is destined for large scale printing.
- Why don't my prints match my screen?
A short article showing why there is more to getting your prints to match your screen, than just calibrating your monitor. It's the vital first step, but you do need to consider some other factors for best results.
- Why are my prints too dark?
One of the more common printing problems we get asked about. Addresses some of the steps you can take to produce more consistent prints.
- Dark prints revisited - If you're having problems adjusting your monitor, Keith has some details of an experimental approach, using adjustment curve layers that may be of some help.
- Choosing a working space
There are a number of popular choices for working colour space when editing images. Keith shows examples and discusses his personal choices for different applications. One size definitely does not fit all.
- Room and office decoration and lighting for photo editing
Some information on what to consider when setting up a space to work on digital images and evaluate prints.
- The very simple guide to 'what is colour mangement'.

- Colour management introduction
- Beware the colour management Tar Pit
Know what levels of colour management (and expense ;-) suit the needs of your work... A personal view from Keith covering some of the things it is good for, but also why you should be careful to understand why you are doing it in the first place.
- Printer test images
- Media settings and profiling for third party inks
Keith recently converted an Epson Stylus COLOR 1160 to third party inks. In describing the profiling of a this set-up with a third party glossy paper, he shows how that often neglected aspect of profiling -driver media settings- can make all the difference between a so-so print and one that he would be happy to send out as a sample to his commercial clients. Test images for media selection.

- Using the ColorMunki for black and white with QTR
A special version of our black and white test print for reading linearisation data for QTR
- Using QTR and PrintFIX PRO for better black and white prints
By using the PrintFIX PRO to take readings from a greyscale test target, you can create luminance only icc profiles that can give a noticeable improvement to black and white print set-ups. It can even be used to improve the results from the likes of Epson's new 'advanced black and white' print settings.
