Why do I need to do calibration myself?

I profili generici non sono generalmente affidabili: quando un produttore crea un nuovo modello, prende solo pochi elementi dalla linea di produzione e li assembla insieme.

Averaged profiles

Display panels differ quite a lot from unit to unit and change substantially as the display ages. It is also more difficult for printers, as just changing the type or weight of paper can invalidate the characterization state and make the profile inaccurate.

The best way of ensuring the profile you have is accurate is by doing the calibration yourself, or by letting an external company supply you with a profile based on your exact characterization state.
