BTW I promised that after I had news and or tried the Baryta on a roll format printer I would report back:
There were zero problems for feed, tractor pizza wheel marks, roller marks on the back, compression in the way of pinch rollers, nothing at all.
The Z 3200 did have an issue with the GE on one pass. I don't know if that was the printer or the media.
There was a sort of raised area in the middle of one print looking like a water mark embedded or water that had swollen up about 5 cm wide by 2 cm wide, surface height difference maybe 0.5mm or less. I've not had any surface defects on sheet.
Handling of the roll paper is much easier than most FA photo type papers I've seen. It just doesn't kink and doesn't scratch much at all. As I said Hahenmuhle papers are best handled with gloves though as the unprinted areas are prone to picking up hand prints.
Since many other Baryta papers have some curled edges, this one is nice to see without problems and is extremely flat. There is zero risk of head strikes in normal humidity.
