White point claibration

Hi, I’m using the Piezography DN pro system, pro ink, the new linearization tool, etc to print Pt/Pd. I’ve been working under the same conditions and iterating a curve. It keeps swinging wildly, I’ll limit, measure, make a new curve and all my whites are blown out, I’ll measure that one, make a new curve and it has swung in the other direction. I’ve started over multiple times with the same result. I’m wondering if my problem is that the white point my i1profiler is using is so far from the white of my Arches Platine. Should I be using the white point disk that comes with the i1Profiler or should I do the white point calibration on a uncoated part of my paper? Thanks!

You calibrate on the i1 profiler’s white plastic calibration disk.

A few workflow questions…

  1. Can I assume that before you began linearizing that you have first established your correct standard exposure time or unprinted Pictorico Ultra Premium OHP film?

  2. What is the name of the PiezoDN target that you are printing on film to contact print with?

  3. What is the name of the starting Curve you are using to print that target?

  4. From which application are you printing this target?

After these answers I may want to see your spreadsheets…

best,

Jon
