Thanks guys. I am not trying to improve the archival quality of the prints, but rather just deepen the blacks a little for some added pop. It works with MGWT, but from what you are saying it does not work with MGIV. I can get a very slight--and unwanted--color shift with MGIV, but it looks slightly purple. Any suggestions on a non-warmtone paper to get really deep blacks? Is graded FB the answer? Mind you, I can certainly get plenty of black by way of exposure and filters, but I want to keep as much of the wet print look as possible. As I mentioned, with MGWT I can get it. I just want a cooler paper for certain things. Thanks.
