I got the sample pack years ago for some reason to try out inkjet printing. it sat unused for a while then I found it 2 yeasr ago after losing the ability to wet print. I found a neg I liked and printed well when wet printed. I also found most of the prints needed some post contrast added but still had, to my eyes, a flatness to them. then when i was down to like my last sheet, I found my solution. the metallic paper! all of a sudden my prints has a sparkle, a nice contrast level and again to my eyes the best whites and blacks that I have achieved in B&W inkjet printing. all the prints were used with a canon pro-1000 printer, so no special black ink set. I always set the output to B&W print so I believe it only uses the 3 black inks in the set. so when red river had a special deal on a 17 inch 100 foot roll of the paper for very cheap, I bought it and have been cutting sizes I need as my canon does not have a roll paper option. if you havent tried that paper, let me know and ill cut a few sheets for you to try
I make sure to always use the proper paper profile, highest quality setting and never over sharpen! to me thats the kiss of death in digital printing. also, for what its worth, almost all my best results have come from negs developed in pryo-M, with a few back in the days when I shot a lot of rollei retro 80s and developed in beutler.
