<title>Why do I need to do calibration myself?</title>
17
Generic profiles are usually bad.
18
When a manufacturer creates a new model, they just take a few items
19
from the production line and average them together:

27
Display panels differ quite a lot from unit to unit and change
28
substantially as the display ages.
29
It is also more difficult for printers, as just changing the type
30
or weight of paper can invalidate the characterization state and
31
make the profile inaccurate.
35
The best way of ensuring the profile you have is accurate is by doing
36
the calibration yourself, or by letting an external company supply
37
you with a profile based on your exact characterization state.
