I don't like getting into these threads, but for what it's worth, this is not an "MIS" forum. It is the forum where B&W inks are discussed.
My PDFs in recent year have been rather generic. One of the major impacts on the market by me has been my generic matte dilution base formula. MIS sells it not because it's "their" ink, but because it probably took a big bite out of their sales and this was a way to recapture some of that revenue. Some very high volume users save lots of money by using it. The "variable tone" inksets I've been installing in my systems are, among other things, designed specifically to be as generic and flexible as possible. Any company's carbon and toner mix will plug into them. I think this more generic, simpler open approach might help the shrinking non-OEM market survive.
In my PDFs I note that MIS sells the inks I use, but I also note the STS ink designation. Canon pigments are used for the toner. STS inks are used for the carbon. What MIS does, among other things, is make the STS inks available in smaller quantities.
I don't know of any other forum that has the expertise that this one does regarding B&W and is open to discussing any B&W ink product or process. (Whether there is a better platform than Yahoo is a different issue.)
Just for a reality check, I contacted a couple of people who buy MIS color inks. No problems. I have no idea what the MIS "error rate" is, and I'm not in a position to find out.
(This is the last post I will make in this thread.)
