that's not the point. Every workflow (technique, paper, ink, printer) has a
different input - output curve and therefore it should be calibrated
individually. With colors you can use the icc standard and the corresponding
measuring tools and software to control the hardware (if you are willing to
spend a few thousand bugs). With Piezo it is different and you have to
adjust the monitor visually to match the print and compensate for individual
hardware (the other way round and not totally equivalent). If you have
achieved a pretty good match you should adjust your image in the appropriate
way to get the "right" print. As a result your image data are changed and
somewhat different if you print with Woolfs workflow or with the Piezo
driver.

You could use Tylers method and Photoshops color management to recalculate
the image data if you have saved your dot gain curves as icc profiles for
each workflow. But I think this is not really recommended in the Piezo
manual for one reason or the other...
