As I continue on my journey, I decided to look at some CMY
separations (printed pos, not negative) on the web tonight and in some books I
have (Benson - The Printed Picture). I wanted to see what they looked like in
terms of relative density, etc. It was interesting to note that the Y
separations, looked much denser than the C and M. In fact, large parts of the
shadows look almost blocked on the Y.
I was curious because today I printed a first layer Y,
using more pigment in the mixture (1 gram / 9ml gum) rather than my previous (.6
gram / 9ml gum). The neg remained the same and I cleared for 20 minutes, and it
looks much darker than any other Y layer I've printed thus far, but holding
detail quite well.
Tomorrow I'll try to finish it and see what I come up
with. I think this is a move in the right direction.
Thanks for letting me collect my thoughts
here...

Christina and all...
As I adjust one variable at a time and ponder the
results, I feel I'm honing in on a stable workflow. The considerable advice
and help from many including yourself, Keith, Marek, Jim, Loris and Katharine
has been absolutely invaluable.
I'm able to do some work today and tomorrow, so I'll see
what I can get happening.

Sounds like you got it all under control, then, Paul,
except for the one ingredient, then, of practice practice
practice....
But as we learn so often on this list, what may work
for Keith with his particular negatives doesn't always directly translate.
I'm not sure what negatives Keith uses--he used to use
imagesetter.
I think all the advice Marek gave is great advice
so I won't repeat....

Christina...
My exposures are approx 2 1/2 to 2 3/4 minutes in
the sun (unwavering bright, cloudless So California sun,
mid-day).
It takes about 10-15 to see pigment in the
water.
Negs are made with an Epson 3800 and its Ultrachrome
3 ink set (standard) and using QTR as the RIP.
I should mention that I found out how to reduce
density with QTR last night, and will be trying that in the next few
days.
I use WN Cadmium Yellow Pale, Sennelier Bright Red,
WN Pthalo Ble GS pigments on Fabriano EW 140 lb.
Gum mixture is: .6g pigment / 9ml gum
to 12ml pot dich (13%)
I also should mention that my intention is to get a
full rendition 3 layer print, a la Keith Taylor (those are his ratios
above). I've read his Ag article (available on Lulu for a pittance) and
also there is now a great feature in the May/June View
Camera.
Thanks!

How long is your exposure, Paul, and when you put
it in the developing water, does it "stream off" the image area
immediately or gradually?
How do you make your negs? What printer,
ink, etc.?

Hello everyone...hope you had a nice
weekend.
I tried another 3 layer gum print (same image as
before) and althought the colors are better than the last time I did 3
layers only, I'm not getting enough color down to give my print a nice
strong density. I'm getting good strong color in the clear
borders...
I'm getting good clearing in approx 20-40
minutes...
My guess is I should be using a less dense
negative. Do you all concur?
Thanks to everyone for your help...
Paul
