No ColorBase as I recall but we're going back a number of years.
Epson uses ColorBase at the factory to linearize every printer coming out. Pretty cool! You can see how great the results are.
And at least two were from pretty high volume users although the term (high volume) is up to interpretation.
I'm thinking 4-20 hours of printing 5+ days a week. 5 prints a day average doesn't count.
Are the needs to recalibrate the Canon less in the same kinds of production environments?
No. Neither printer drifts enough for the average consumer to notice in the lifespan of the printer. High volume pros tend to calibrate their Canon's every 4-6 months and Epson's every 9-12 months.
