Homebrew PCBs

I have a few questions about the mis-pro direct inkjet printing
method.  I saw it mentioned that the durabrite inks may soften during
etching, is the same true of the mis-pro ink?  Also, has anyone tried
mis-pro ink with a CuCl Etch?  I'm asking becuase I'm in the process
of wrapping up an Epson c88 conversion and am about done building a
spray etching machine.  I've been using CuCL etchant for some time and
would hate to have to change.  The spray etcher has a pretty aggresive
spray and I am concerned it washing the traced from the board.

Can anyone provide additional info?
