Yes Dick I am still lurking about,thanks for the mention.Anyway the
technique that I devised was not that original, being a straight ripoff
from the Kodak system of stripping of colour C/Types for mounting down onto
canvas all the vogue in colour portraiture in the middle 70's.
As my book is well out of print here is a
description of a technique
I finally adopted, which worked very well and hardly ever tore.
First laminate the surface of the print allowing a
surplus of 1inch of laminate all round the print,next selotape this surplus
down onto glass or smooth plastic, then take a wooden ruler or straight
edge and sharply tap the top layer of the resin coating, after a few taps
the top layer will begin to curl up and separate from the base, then take
hold of this top layer firmly and gently pull up, until about a 1/2 inch
off top layer is clear right along the print .
Take this strip and attach it to a wooden dowel
with selotape , then gently roll the dowel across the back of the print
until all the top layer comes away. There will still be
quite a bit loose paper fibre attached to the print , this is now removed
by making up a 50%solution of Sod Hydroxide, please be very careful at this
stage as this solution is highly caustic so use protective clothing and
gloves, take a pad of cotton wool and pour the caustic soda onto the centre
of the print and gently polish towards the edges until the resultant wood
pulp becomes a white goo, wash this goo off with clean water dry with a
hair dryer strip the print from the glass, and you have a perfect lightly
translucent image which transmits from ten to twenty times the amount of
light when compared to a normal resin coated print .
Hope this helps
Ps Dan Estabrook 's method is something new and innovative, I am intrigued
to know how the wax penetrates the polyurethane top coating of the print
maybe it is due to the heating effect of the iron, any way certainly a new
avenue of approach this is what is so fascinating about photo/alt always
something new to learn.
BTW I have found that sunflower oil works great on paper negs produced on my
Epson 1520 perhaps you could give it a try Dan ?
