Could be, I'll see it for myself (in gum printing context) as soon as I purchase: two large sheets of heavy glass (to sandwich the paper and negative in between), a high density thin polystyrene foam sheet (for cushioning / even pressure distribution), matte black spray paint (for painting the light colored foam sheet so that it doesn't reflect UV), and small C-clamps (to fasten & apply pressure to the assembly) in order to home-build a large contact printing frame and test the paper in large sizes. (I already need that for large prints on Fabriano.) BTW, you may have missed that I mentioned before that I soaked that paper for long times, at full and half sheet sizes (but not for gum printing), not caring much about delicacy in handling (albeit I wasn't particularly heavy handed too) w/o any cracking. On the other hand, I remember Keith mentioning that the paper won't do well after 2 gum layers (if I'm not mistaking) being as inexperienced as I am, I easily did three coats without any problems (apart uneven coating). Those facts still makes me think that the difference may be caused by the relatively weaker weight of your stock.

Thanks for the insight. I haven't experienced any dragging myself but felt the coating wasn't even enough with thick emulsion. Did you also realized that the paper needs much less emulsion (about 1/2) than Fabriano (or similar sturdy / heavy papers)? I'm sure thinner emulsion will do the trick in the future, combined with getting more and more used to the paper... Regards, Loris.
