Colour Management Information

If you have a calibrated monitor, we strongly advise submitting your images assigned with default RGB Profiles, either sRGB or Adobe1998 for best results.

Our technicians will convert from your assigned input profile using industry best practices to our specified output printer and paper profiles based on your product selection.

Monitor Starting Points

1. Set your monitor white point to 6500 Kelvin or (D65). (Read your monitor manual for more information on changing the white point settings.)

Check the patches marked 0 and 10 in the grey scale; do they appear to be the same? If you cannot see a visible difference, your monitor is too dark. Check the patches marked 95 and 100, if there is no difference then your monitor is too light. If the patches have a colour cast, you can correct problem by calibrating your monitors' gamma for each colour channel individually.


2. Stand 3 meters away from your monitor and check the image below. If the centre patch is darker or lighter than the background then your gamma will need calibration.

Gamma Patch

Access the Adobe Gamma in Control Panel for PC's or for Mac OS X System Preferences panel open the Displays and choose 'Wizard'. Follow the step by step calibration process. Save your new monitor profile.

3. Go Photoshop Edit / Colour Settings

  • RGB Working Space; Start with sRGB or Adobe1998 colour working space
  • Color Management Policies; Preserve Embedded Profiles

For best results submit prints assigned with either sRGB or Adobe1998 icc profiles only

Which shot below is correct? Without a calibrated monitor it will make it very difficult to gain an accurate and consistent output result The image in the top right is an example of a correct exposure.
