If you only want to do B&W printing, rebuild it with Split Grade from Heiland. 100% reproducible: HLX on, shutter open 00 (Y), 5 (M), shutter closed, HLX off.

Further you have in one measurement optimum time and gradation. All sensiometric values are stored in the Heiland console. It is very easy to print directly, without calibration, almost 100% results.

best regards,
