old toner transfer paper trivia

[Werner Almesberger]

I couldn't find my bag with the toner transfer paper I had used in
recent years (some random brand ink photo paper), so I used the one
I could find - a sheet of the venerable HP C6039A.

I had this for about ten years (luckily inside a plastic bag, so
the thick layer of oily black dust that had accumulated over the
years wasn't on the paper itself) and time has done interesting
things to it.

The first indication was when, after printing, a corner of the
paper delaminated:

I knew the coating had a key role in making toner transfer work,
but I never pictured it as a separate film.

After passing the laminator ("ironing"), the film detached
completely, yielding this:

Except for the weird splotch under the "A" of "ANELOK", the
transfer was flawless.

I thought it looked very good.

Some friends of mine did their own circuit boards but merely used what they
referred to as "cooking paper": what would be called "greaseproof paper" in
British English. The result was pretty effective, as I understand it, but then
they also have chemistry backgrounds and can presumably be relied upon to get
things right first time. :-)

Oh, that's a nice idea ! Have to try that. This would be much easier
to find than suitable ink paper, let alone much cheaper.

I think they found out about it from some online guide. Once we'd discovered
that laser printers can't feed such paper through very well, and I'd suggested
taping it to normal paper, that part worked pretty well. Their chemistry
discipline made the rest of the exercise straightforward, as I understand it.
