Subject: [Digital BW] Re: Hahnemuhle flaking


Djon, I just noticed this reply from you.  I'll elaborate on my
printing process and environment.

First of all, I have found no problems with other papers in the same
environment, with the exception of Moab Entrada.  I have used
Somerset, Epson Premium Luster, and EEM.  None of these have "flaked".

Nevertheless, dust could be an issue.  I am in a very dry climate,
and perhaps the HPR developes a static charge that picks up dust.  It
could also be the ink density. I only notice the problem with B/W
prints, especially in the lightest greys.  I do not see it in my
color work.

At any rate, my lint roller solution seems to be working for now, and
after I'm finished with these rolls of HPR, maybe I'll try some of
the alternatives suggested here.  I'm not eager to abandon the HPR,
because it took me some time, and wasted paper, to refine the
workflow.

Jack
