How often should I re-profile? How will I know when my profile no longer matches up with my printer
Profiling and Calibrating FAQ's -
How often you need to profile is dependent on your printer - each one is different and has a different time scale in which it would need a new profile making.
We normally recommend to re-profile every six months to a year to ensure you are getting the most accurate colours from the printer.
When the current profile no longer matches up with your printer, you will notice a shift in the colours being produced. This will happen quite suddenly; you may notice a colour caste appear over your prints, or certain colours no longer printing accurately when compared with a calibrated screen.
