I would like to write about it here, but I think I am taking too many liberties as it is.
Ron Reeder and others on DPUg are experts in Digital Negs using epson printers with QTR. I am making negs by my eyes and the numbers on the info palette.
for the lambda negs my machine calibrates the film in 21 step wedges of white to gray with D min and D max settings put forth and the machine calibrates as I make the negs.
I am not an expert in any way in making the inkjet negs and Ron and others are way more experienced than I.
But with that said, making negs for lith printing is as simple as this.
ok so I will take a chance
put pictorico in the printer.
Convert to black and white with your favourite method and edit and sharpen as normal
Adobe 1998 - make your image look great with your highlights almost blowing out and get deep deep blacks
Image size 300 dpi then set your size.
flip horizontal = so when your image is laying on the silver gelatin paper the image should be emulsion down right reading
invert image- now you have a negative
save as to a folder
open image in PS send to printer and make your inkjet neg.
test in in a real darkroom using historically chemicals like photospeed lith, stop , fix, fix, hypo wash ,, then tone as you normally would.
I really liked the Foma as suggested and I really like 1:8 dilution, also I really like blasting the exposure form one enlarger.
Have some fun.
The second flash will fill in the burnt out highlights , that will give the toner something to hold on.
I applaud as well. I would also like to know A LOT more about "epson negs on Pictorico Ultra premium OHP film" and the flashing technique. I know you're busy, Bob, but is there a reference for making those negs? Or would you write about it here or on DPUG? I am interested both for enlarging negatives for alt process and for converting digital files (although I shoot very little digital).
Great work!
