RPN is a high energy neutral print developer that in our view is black and white photo chemistry at its finest.
Rollei Print Neutral is one of the best paper developers we sell because not only do you get premium quality which can be used for development in dishes or processing machines but it offers an unsurpassed Dmax and extremely low fog level. For educational departments you'll find that you can leave it in a dish for weeks on end due to its stable and long working life.
Dilution for normal development is 1+9 but other oprions includes less or more for increased or decreased contrast and as low as 1+2 for exremely rapid processing.
RPN is also a constiuent part of Rollei's Black Magic photo emulsion system.
