<title>Why do I need to do calibration myself?</title>
23
Generic profiles are usually bad.
24
When a manufacturer creates a new model, they just take a few items
25
from the production line and average them together:

Display panels differ quite a lot from unit to unit and change
34
substantially as the display ages.
35
It is also more difficult for printers, as just changing the type
36
or weight of paper can invalidate the characterization state and
37
make the profile inaccurate.
41
The best way of ensuring the profile you have is accurate is by doing
42
the calibration yourself, or by letting an external company supply
43
you with a profile based on your exact characterization state.
