Digital BW, The Print

Well I've finally worked up my nerve enough to attempt to make a 
digitally enlarged ink jet negative. I've been reading and re-reading 
Burkholder's second book on the topic and plan to use the Pictorico 
OHP Transparency Film and MIS-VM inks (cool tone) printed on an 1160. 
But of course I do have some questions.

1) What media type should I use in the Epson driver setting?

2) I plan on starting with the Piezo curve supplied by Dan on his web 
site unless someone can point me to a better solution. Since the 
Epson driver outputs in 8 bit instead of 16 bit (like the Cone 
software produces)  is there any chance that enough ink density can 
be sprayed onto the OHPTM?

3) Does it matter which order the two adjustment curves are applied? 
I would think that since Dan's curve is not partitioned his curve 
would need to be used first in gray scale mode. After which RGB 
conversion would be made to enable the VMQC curve. Does that make 
sense?

4) I assume that the MIS quad tone inks will need to be sprayed. 
Should I use the Krylon clear spray? How long does the spray have to 
dry? I've heard from another user on another list that the Krylon 
product compresses the mid-tones in platinum palladium prints. Any 
comments about this would be helpfull and appreciated.

5) Has anyone sucessfully made digital inkjet negatives for 
contacting onto silver gelatin papers? I would assume the approach 
would be similar to the platinum conversion. It seems to me that 
initially using silver gelatin paper would provide a quicker (and 
less expensive) iterative process than an alternative process such as 
platinum printing, at least to work out the basic kinks common to 
both.

Thanks,
