Thanks for the good news Mirko. I would personally be most interested in 30x40 (12x16) size, and I'm obviously happy with your intent to get this size out with the first production. While I *much* prefer 50 sheet boxes, the 25 sheet envelopes will be fine too if their pricing is not objectionable.
The paper I currently use is Kentmere FPVC Baryt, which I quite like compared to Agfa's barite paper that I used to use. The Agfa paper was a bit thinner than is Kentmere. I understand that both the Agfa and the new Adox are 180 g/m2, against 240 g/m2 for Kentmere. I prefer the thicker paper, but of course there are other properties more important than weight.
I'm very curious about the new Adox, and I will definitely try some.
Good luck getting it all to work out Mirko!
Cheers, Sander.
