  <title>Can I get notified when my color profile is inaccurate?</title>
  <p>
    Unfortunately we can't tell without recalibrating whether a device
    profile is accurate.
    We can use a simple metric of the amount of time since calibration
    to determine if a recalibrate is recommended.
  </p>
  <p>
    Some companies have very specific timeout policies for profiles, as
    an inaccurate color profile can make a huge difference to an end
    product.
  </p>
  <p>
    If you set the timeout policy and a profile is older than the
    policy then a red warning triangle will be shown in the
    <guiseq><gui>System Settings</gui><gui>Color</gui></guiseq> dialog
    next to the profile.
    A warning notification will also be shown every time you log into
    your computer.
  </p>
  <p>
    To set the policy for display and printer devices, you specify the
    maximum age of the profile in days:
