Hi Paul,

With transparencies, you should use a thin cloth or double/quadruple 
layer of paper towel.  I set the temp on my iron to somewhere around 
wool or cotton.  I've used linen, but that's too hot and discolors the 
paper towel I use to protect the transparency.

Direct contact between the iron and transparency will make the 
transparency melt.

You want to get sufficient toner melting to get good transfer and 
minimal pitting, but not enough to cause enough smearing to cause 
shorts.

I've been using HP inkjet transparencies (non Premium version) and hav 
been getting good results.  I have some pitting, particularly in 
copper fills.  The fill areas are easily touched up with a marker - I 
use fine point black Sharpie.

I just tried some Compusa inkjet transparencies.  They work, but not 
as well as HP.  They're about 2/3 of the price of HP, so I'd like to 
try tweaking my ironing.

There is a film that should be removed before etching, but mild 
scrubbing with a little water and liquid hand soap and a toothbrush 
does it for me.

Regards,
Dennis
