Digital BW, The Print

Thanks Paul,
I'll try your UT14 suggestion.
I don't know anything about making curves yet but have read your directions for making ICC profiles.
Would my old XRite 400 B&W densitometer be OK for reading the step wedge values? My only scanner is the one on my Brother office printer and I don't know how good it is. I only use it for drawings and electrical schematics.
