 saved  their images for straight piezo prints  - and now want to 
 print  MIS Full Spectrum Inks through the Cone Driver and have 
 saved  their images for straight piezo prints ....  (puuuh) .... I have 
 worked out  a curve which should bring identicall prints with the 
 MIS FS inks - at least on an 1160. 
 I calibrated with my eyeballs printing the 21 step image and 
 checked it with my print exchange picture, which I printed with 
 both inks innert 5 minutes on two 1160s.
 (Result: can´t tell the 21 steps prints and the two images apart.)
 
 Specification:
 1160 printer, works on EAM and Photo Rag with the Orwell 
 profile.
 
 Here is how I do it:
 In PS open a file which is saved for Piezo printing
 Go:   >Image>adjust>curves
 
 fix the 95 % value
 
 change the following values:
 85 > 88
 81 > 84
 75 > 80
 50 > 57
 25 > 32
   5 > 7
 
 Save Curve as starting point for later images and fine tuning, 
 apply curve, print.
 
 If anybody gives it a try ... let me know how it works.

I know this is an old post, but I was wondering if anybody gave this method a 
try, and if so, how it worked. I keep seeing the green metamerism with my 
Piezo inks and am considering switching.
Thanks for your input,
