And WTF has this all now got to do with TT !

I found some epson 4∗6 photo paper, had a go, not much use it seemed
to crack the image on it like a mirror.

I have now got a bottle of gum arabic, tried kodak paper coated with
that, made toner stick to paper like glue but not to the board!


I just had another go back with the Kodak paper, I did the usual but
applied heat for 3 minutes directly onto the paper and it went brown!

It did not stick to the iron, in fact at full heat it was like ironing
teflon, I left it to soak about 15 minutes, not a thing, its got to be
the most resiliant paper made for photos.

I started to wirewool through the paper layers at a time until it was
thin enough to see the image very cleary, I kept working at it till I
was down to the toner and copper, result, an hour or so of rubbing,
one near perfect board.....

The toner areas where THICK, really thick, the paper is evil but made
for a good etch.

So, kodak will work, bt it takes work, and I need new skin for my
thumbs..........

Off to do another board now....
