Basically, Ctein obtained a very high resolution bar chart which he contact printed onto various papers. There is some discussion of test procedures(exposure and firm contact with the paper). He found that the single grade papers were somewhat sharper than the multigrade and that the multigrade at grade 0 were softer than the same multigrade paper at 5. However, even the worst case test paper Multigrade IV RC at 80Y was resolving over 50 lp/mm. The best paper was Flexicon VC at 140 lp/mm under 200M filtration. So, unless we are enlarging paper negatives the printing paper is not the weak link. Don dorysrus@mindspring.com - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
