The R3000 uses the same printer driver in QTR as does the R2880 (and several other models). We do not use Proof of Piezography anymore… Download the Linearization checker from the custom curves page and run that using an Eye1 for the measurements. you can quickly determine if you are linear or not…
Download it from the instructions page here: Custom Piezography Curves
If I had an Eye1 I wouldn’t have posted my query in the first place. I’m relying on an eyeball estimate that the region from 90% to 100% [I]may[/I] need attention. While you may not use the PoP anymore, it must still be valid, if somewhat limited.
Would you consider providing a service that would provide a linearity check to your regular customers (at a price, of course?) Otherwise, the only way to allay my concern would be order a custom profile, at $99, perhaps unnecessarily.
Alternatively, perhaps there is someone following this thread who would provide a linearity check for a reasonable fee?
