Harman Gloss Baryta! My favorite gloss paper! That was too close for comfort. Incredible tonal range and just plain gorgeous on my iPF8300 and 8400. Jaw dropping, and that's the truth. My profiles show Lab 1 to 98, with 99 strongly suspected. Incredble sparkling highlights and gorgeous, glowing, beautifully textured darks. Haven't seen any particular surface problems with my Print Shield coated prints.
Count me in on the "curl" complaints. Like every other alpha cellulose paper I have used, the curl is too great to avoid head strikes. The cure on my Canon wide format printers is to sacrifice the first 8" of paper to get past the curl created by parking in the sharp turn in the feed path of those printers. And then to print as much of the roll as possible in a single session.
Dear Hahnemühle: as long as you are changing the surface coating, how about also changing the substrate to nice, soft, flexible cotton rag at maybe 260 gsm? At least for the rolls. Will gladly pay a bit extra for that option.
