Re: 3 layer gum on Masa affixed to Yupo
Hi Loris,
Looks like Yupo + adhesive is the way to go with Masa, if registration
is desired. In my experience, Masa on which a cyano pass has been done
and is gelatin-sized, shrinks uniformly by about 2 mm per 9 x 10.75"
paper.
I just learned that there are 3 types of 3M Photomount spray. One is a
'regular', another is a 'reconditioner' which takes long to dry, and a
third one is the most expensive. Could you possibly provide details of
the label of the 3M you have used?
Thank you! Rajul

Hi all,
This is my very first finalized gum print - so don't be too harsh ;)
Affixing Masa to Yupo using 3M Photo Mount spray adhesive worked well
for me;
a) No more registration problems - thanks to the stable base, I can
perfectly register the negative while doing multi-layer prints. I
couldn't manage this before affixing the paper to a stable base.
b) From now on, I can make a 3 layer gum print in less than 2 hours...
Here's the print:

Tonality and subtlety is poor compared to Artistico. But this combo
surely works when you're in pursuit of this particular look and/or you
prefer to work quick. (Please note that this is a fairly small print;
only ~ 6x9"...)
This image consists of three layers:
1. Ivory black, 10% Ammonium Dichromate, 2:22
2. Yellow raw ochre, 10% Ammonium Dichromate, 3:00 (This is a mixture
of PY42 + PY43, I guess I will put this as the first layer since I
didn't like it on top of neutral gray/black...)
3. Ivory black + process cyan, 5% Ammonium Dichromate, 1:55
Will also try to print this over with a Cyanotype first-layer.
The actual image is cooler and less grainy compared to the scan -
calibration and interpolation problems. It's an OK reproduction...
Regards,
Loris.
