Just one more thing maybe...
i wonder, how you do it after ironing-or laminator stuff is 
done...is it good to put it immediately - as soon as possible into 
hot (or cold?) water, or is it better idea to wait until toner is 
cooled down - i imagine that after iron is lifted, toner is still in 
liquid state and so putting it into water immediately can affect 
this on the very edges - especially with my current paper (laser 
soft gloss) which soakes very quickly---in seconds at the edges, 1 
minute tops for whole plate---
