Digital BW, The Print

John,

For matte papers I like Lascaux Fixativ.  It decreases the dmax considerably
less than the ones you mentioned.  However, I don't know if it will do any
better job with respect to rub-off.

I'm speculating, but I'd guess that some other paper would have less of a
problem.  That PhotoRag surface seems to be a sensitive one.  PremierArt 205
is dual sided.  

By the way, although I'm not familiar with the PhotoRag dual sided paper,
with most I've used the concave side is not as smooth as the convex side.

Subject: [Digital BW] Dual Sided Printing for Books on Rag Media Without
Ruboff ???



Does anyone know of a coating to apply to Hahnemuhle Photo Rag dual sided
308 paper 
that will actually seal the blacks from transfering on to facing pages. I
have done a number 
of books for graduating photo and design students with this wonderful paper
and have 
always sprayed it with Premier Art and Lyson Printguard in two heavy coats.
However, we 
are still seeing black ink transfer to facing pages within a short period of
time.

Now I have a client who wants to produce very high-end wedding portrait
books, leather 
bound with a fine rag paper but we are facing this same issue of ink
transfer. We don't 
have to use rag paper but I would prefer to.

So, is there a coating, laquer, or something that I could use to stop this
from happening? It 
seems to me that I remember Paul Roark talking about some sealant he was
using. Any 
other ideas?

This paper ideally would be a relatively heavy fine rag media. I know
Somerset and 
Concorde Rag have the coating more down in the paper, but they aren't dual
sided and 
would probably transfer blacks anyway with the sprays that I've been using.

Any suggestions would be helpful,

John
