I found ImageOn HD to be a pain. Someone here on Orchid mentioned a
different product, “Toner Transfer Paper” from Pulsar
( http://www.ganoksin.com/gnkurl/dc ).
The company is marketing to printed circuit board hobby electronics
buffs. It is basically paper that is coated with dextrin (a starch)
that is run through the laser printer. The toner transfers to the
paper then you iron on the image to your metal and then place the
metal and paper into water. The starch dissolves allowing the paper
to float free of the toner. This has a big advantage over the acetate
method in that it transfers all of the toner not just some of it. I
have very good results with it.
The two biggest issues I see with theses processes that use the
laser printer toner are that the metal is not clean enough and second
and maybe the biggest issue is the metal may not be perfectly flat or
the iron is not held perfectly flat on the metal. The cleanliness is
easy to solve with products like Barkeepers Friend or Clean King
scouring powder. Both of these use pummice and a mild acid to really
clean the surface of your metal. The second issue is a little harder
to diagnose but if you have really clean metal but you only get
partial adhesion of the toner then it is likely you are not getting
the transfer paper, acetate or, PNP fully flat and in contact with
the metal. The trick I have been using is to buy a piece of 1/16"
thick silicone rubber and placing the rubber between the iron and the
paper or acetate. Silicone rubber will transfer the heat to the
paper/metal stack and greatly reduce issues of not having everything
perfectly flat. Once I started using the rubber my success rate went
up to near 100% for such transfers.
