I have been playing with the various types of paper I can find
(coated, shiny, plastic foils etc). So far I have had the best luck
with an 80lb plain polished paper (it is quite shiny but no coating I
can detect). The combination that has worked the best is preheat the
board for 3 minutes and iron with gentle pressure (ie a little more
than the weight of the iron) for 30 seconds. The problem I am having
is getting the paper off when I have finished ironing. If I soak it
overnight I am fine but I would like to speed up the softening
process. Any suggestions? I was thinking of boiling water but I
suspect that will soften the toner to much. Are there any safe
chemicals that will soften the paper but not destroy the copper or my
kitchen?

My second question is if anybody knows of a way to get the printer to
deposit more toner. I am using an HP 1200 laserjet (which is great)
but I am getting better results if I run the paper through twice.
The problem with this is I don't always get perfect registration.

I use Dyna Art. The paper just floats off in mildly warm water after
ironing. IIRC, this paper is coated with a a layer of sugar, so that
might be the secret.

Perhaps you could experiment by spraying your paper with a solution of
sugar in water, and letting it dry before using it.

There is a way in my printer software (I have a Panasonic KXP-6500) to
specify greater toner density. I'd call HP printer support and ask
them if this is possible with your machine. The other option is to
look for denser toner. I understand it is made, apparently for use
in printing graphics, but I don't know where to look for it. There are
lots of toner supply companies on the net and elsewhere. Or perhaps a
copy house which also does laser printing could tell you.
