Digital BW, The Print

Cross post also to PiezoBW list. Sorry for inconvenience.

Hi all,

I've got a friend interested in PiezographyBW who lives in hot, humid 
Bankok, Thailand and he wants to know how Piezo prints hold up in the 
somewhat intimidating heat/humidity of the Far East. His matted and 
framed Fuji Pictography BW prints have seriously colour shifted - both 
inks and paper - due to the climate. Any Piezo users in this part of the 
world with experience in the matter?

I've printed a couple of his files for him (here in Paris) using PiezoBW 
on an 1160 which he has comapred to A3+ size prints he has made on a Fuji 
pro printer using a BW curve made for him by Bruce Fraser, hanging on 
walls in his Paris apartment. He likes the Piezo output a lot. The tones 
are warmer than his Fuji output but fine for him. He is considering 
buying an Epson printer (1160 if we can find one for him here in Europe) 
and going with PiezoBW but would like to know how they will fare in his 
quite inhospitable climate back home. I'd appreciate hearing from anyone 
with experience in a hot humid environment using PiezoBW.

Thanks,

Nina
