Homebrew PCBs

I have been following the inkjet process with great interest. I am
curious though if the curing process is some kind of oxidation of the
pigment or some other process. 

Perhaps some kind of enclosure for the hot plate (an upside down pan)
and using something like helium to displace the oxygen might provide
some intersting results.

At first i was certain it is just a matter of boiling off all water, but  
now i know i was wrong because the effect starts at above 200C. Maybe it  
is some other component boiling off - some glycol?

Apart from acting as a etch resist the curing will also make the ink much  
more resistant to Acetone. But also air-dried ink will be much more  
resistant to acetone after several days then when fresh.

As far as i know we do not know the composition of MISPRO ink. Maybe  
someone could request a MSDS?
