Digital BW, The Print

I am using the bulk MIS dyes, 4 oz bottles with a NMC CIS.  A set of 6 bottles is only $48.00.
The difference between the MIS dyes and the epson oem carts seems to be that with the OEm inks I would sometimes get a crossover, mainly slightly cyan shadows with slightly magenta highlights.  With the MIS dyes this isn't happening.
I've only used these inks with LPM so far, I will be trying out some somerset enhanced shortly to see if the results are the same.
