Digital BW, The Print

Nowadays it seems to be the trend in galleries to show photo's which
are mounted on Dibond (or some other board) and with no glass.

There are some advantages: you don't have reflections from glass,
obviously. And it is probably less heavy.

Because I can't do large format myself, I was thinking of having a
professional lab print for me on Photo Rag with K3 and mount on
Dibond. For display in galleries and sale purposes.

But I don't know, yet…

Is it not too vulnerable without glass and prone to fading? The man
from the lab said the prints will be treated with some spray, but will
that do?

I was thinking of 17x23 or 23x33 inch prints.

Thanks,
