Steven Posted November 22, 2005 Report Share Posted November 22, 2005 Has anybody any experience of using Kodak Portra B&W paper (RA4)? I have just got a couple of rolls with the idea of producing decent B&W prints but they are coming out pink!! I use Kodak chemistry. I believe there are one or two variants of this paper, does anybody know what the differences are? Quote Link to comment Share on other sites More sharing options...
NeilT Posted November 22, 2005 Report Share Posted November 22, 2005 we used this years back..make sure that you have the paper balance like 10% right, or you will get a pink/magenta cast.. To be also very honest, the results we are getting on colour paper for B&W are as good as any RA4 B&W paper. Quote Link to comment Share on other sites More sharing options...
JP Posted November 22, 2005 Report Share Posted November 22, 2005 Seem to remember this is a problem with bleach/fix. Underactive I think. Paper balance won't effect B&W paper, apart from density. What chemistry d'you use and what machine? Quote Link to comment Share on other sites More sharing options...

Peter Thornton Posted November 23, 2005 Report Share Posted November 23, 2005 My advice (assuming you have a digital lab) is to bin the paper. It's nothing but trouble! Several years ago, I did a whole lot of prints for a customer on the old Ektamax paper. The customer eventually brought back Quote Link to comment Share on other sites More sharing options...
Dave S Posted November 24, 2005 Report Share Posted November 24, 2005 The Ektamax paper was never designed for permanent prints, it was supposed to be used for proof prints only. It Quote Link to comment Share on other sites More sharing options...
JP Posted December 7, 2005 Report Share Posted December 7, 2005 Steven, did you end up getting this paper to print OK? If so were the results any better or different than printing on colour paper? Quote Link to comment Share on other sites More sharing options...
Steven Posted December 10, 2005 Author Report Share Posted December 10, 2005 Hi. We have reduced BF strength on little by little basis, not wanting to cause other problems with colour paper. Unfortunately it hasn't had any effect on B&W paper, its still pink!!! Back to the drawing board. Is it more sensitive to drier temperature, we have noticed some slight blistering which we never get with colour? Quote Link to comment Share on other sites More sharing options...
