Hello Tom,
My name is Lee Pratt and I've been "lurking" on the list for a while. I
too have found it to be a fine group. As this is my first post to the
list, perhaps some others will find my information of interest.
First: You probably know this from Dan, but he is giving a workshop at
Photographers Formulary in Condon, MT, 15--20 June. I've attended two
other workshops there, and have always had a great experience. You can
contact them at:
http://www.workshopsinmontana.com
Second: I too have an Epson 3000, which I have dedicated to b&W work,
using the PiezographyBW drivers and inks. My understanding at this
point is that you only need a "curve" if you are making a contact
negative through a service bureau = using lithographic film. I doubt
you will need any curve to make a desktop negative on your Epson, as
you can simply invert your final image to a negative and print it to
your 3000 on Pictorico OHP film. (Epson transparency film does not
work, but the Pictorico product does.) If your positive looks good on
the screen, the negative will probably print well on #2 paper.
Yesterday I used this process to produce an 8x10 "DCN" = Digital
Contact Negative (my name for these things), which I then printed on
Azo. I've just started doing this, and haven't got all the fine tuning
done, but this look like a dynamite process. Azo is a slow contact
paper with a remarkable long scale and lovely tonality. My first
attempt was more than satisfactory. You could also use enlarging paper
and an enlarger as a light source to print the same "off the screen"
negative, although I've not done this and have no data to share.
For gum bichromate, I understand that one needs a negative of normal
contrast, again producible without any special curve. I too am
interested in gum printing, which I believe Dan is going to cover in
his workshop.
If I've raised more questions than I've provided answers, I'll try to
answer any future queries posted
