Hi,

I started printing on Hahnmühle Photo Rag, with P. Roark's profiles. Great results indeed.
Now, I would like to try on Hahnmühle Bamboo, and perhaps one baryta as well (Hahnmühle Fine Art Baryta or Photo Rag Baryta).

To make the profile for those papers, is it worth starting the job from scratch or can one just linearize from the PhotoRag profile? This should help to save sheets...

Thx
