RH Designs Analyser/Zonemaster calibration of fixed contrast paper

Hello,
the manual of the Zonemaster describes to calibrate the unit for a certain type of (variable contrast) paper.
How to calibrate fixed contrast paper? Should I do the same procedure (for all grades)?
best regards,
Oliver

I would suggest you do the calibration for a single grade. Grade 1, 2 or 3 (soft, normal or hard) depending on the paper you have at hand.

I once tried to use my zonemaster with a graded paper but I could not get the hang of it. Perhaps the densitometer mode is better suited for graded papers.
