Re: "speckling" v "staining " (was New Orleans/glut) SEE SCANS

Thank you, Mark, for your nice scans!

Loris, the "student" was Don Bryant, sized paper, and Mark Nelson, coating.
The amount of sensitizer was equal in both and very low--I only use the
equivalent of 7% am di.

Mark, you have inspired me to size some Rives with glut...it'll be a fur
piece down the road, but by next semester I will do so, as you are
absolutely right that I need that variable. I have sized FAEW with glyoxal
already, but not that you were able to coat while you were here.

If glut WORKS with Rives BFK then it will even moreso prove my point. If it
doesn't, then I would consider Rives not a beginner's choice of paper.

Don is currently going to test glut...on Rives, Don?

I think the images show the point that with all things being equal, a
beginning student will have a MUCH easier time learning how to gum print
when combining a correct size with an easy paper. IMHO, glut and FAEW is
just the ticket.

 Mind you, Don is way less "loosey goosey" than I am with his technique in
alt process. If I had sized the paper I would assume that it was operator
error, but because both Don and I have had this experience with size/paper,
and I have similarly seen glyoxal be gritty on FAEW, I just don't see a
reason to use glyoxal as size of choice. Those who are happy with it, keep
on keeping on. It's not like glyoxal is the devil incarnate.

Hi Chris,

regarding the infamous speckles. As mentioned, there were two papers
coated
used:

Fabriano Artistico Extra White with Gelatin sizing hardened with
Gluteraldehyde

Rives BFK with Gelatin sizing hardened with Glyoxal

The Rives BFK is a more textured paper than the Farbriano—I do not know if
it
was cold press or what, but had obvious more texture.

I wondered if the paper had been scuffed when sized, causing the peaks of
the
texture to not clear, however when I looked at it with a loupe, it appeared
that the "speckles" are located more in the valleys of the texture. Then I
wondered if it was just loose pigment gathering in the valleys, but that
isn't
true because when they were developed in the water, I tried to remove the
"speckles" with a spray and abrasion and it wouldn't go away. The area
that of
the RIVES that I scanned is the area under the most dense steps of the 31
film
step tablet (not digital step tablet) that received relatively no
exposure...
there was no indication of "tone" at all at those steps or on the Artistico
at
the same steps. So whatever occured, happened without exposure and was
fairly even all over the paper regardless of how much exposure it received.

Here are the links to the two spectacular speckled scans for you to
speculate
upon:

Frabriano Artistico Glut & Rives BFK Glyoxal at 3x
Rives BFK Glyoxal at 24x

I do also recall rather vividly when feeling the papers before coating them
that the Fabriano had a smooth feel while the Rives had a gritty feel.
Very
much like when you spray something very lightly with a varnish and the tiny
droplet dry and leave a rough feel to the surface...or a very fine grit
sandpaper.

These are just my observations and I draw no conclusions. I would like to
have seen the same to papers with the hardners reversed. However, I would
probably not waste my time and just go with the Fabriano sized in the manner
it
was, because it printed beautifully. Not as sharp as PT/PD, but not bad—
hehehehe

Best Wishes,
Mark Nelson
