Digital BW, The Print

Loris - I've not tried this and I'm just thinking out loud (I've not had
your symptoms with 308 PR or 190 WT) but how about a curves move before

of black square tests in small increments to decrease the amount of black
laydown stopping where you measure a decrease in density?
