Re: Paper negatives (Re: Tricolor gum, order of layers)
I sent in a while ago info from (as I remember) LeGray on the use of
Would that not do the trick?
Though the ones I make have more recently been on bond copying paper and
created with a 600 dpi laser printer, by working with an old iron, and
paraffin like Guido says. I use a piece of old matte board that's soft
up the extra paraffin.

Could you provide a source for that "white technical oil"? I've
searched in vain with google. I use plenty of baby oil and, to avoid
the mess detailed by Katherine, squirt a little on the negative and
then re-use oily paper towels to rub it in. Honestly, the cloying
smell of that baby oil has permeated my work area to the point of
distraction. I'm hoping the white oil might be more "neutral".

Just rub the reverse side of the negative with a suitable oil.
different oils I settled on "white technical oil", it is as liquid
and has the same (no)
color. I believe it is the same (paraffin) oil sold in smaller cans
sewing-machines, in greater quantities (1 litre) it is very cheap.
rub it generously in and let it sit overnight when all the oil
seems to be
completely absorbed by the paper and for gum I don't even use the
separator sheet (between neg and coating to avoid oil stains)
a few days the oil may evaporate more and the paper becomes less
transparent, just oil again if you want to reuse the negative.
Another method is to use blocks of paraffin on the, heated, reverse
the negative. Use an iron to heat the paper in parts and apply the
ending with rubbing the molten paraffin with a paper towel to
up excess paraffin. Takes a bit of practice but once cooled down
remains translucent and is not oily.

Since I just recently paid about $150 to have 40 sheets of 11x17
shipped to me, I gotta try the paper negative. I have a box of
named photo quality inkjet paper. How do I oil it?
