I've used the Triangle Bulk ink from the day that I bought my machine...........about 3 1/2 years ago.
I did hear that the warranty is void if you run the Triangle bulk ink. That was not the case when I purchased mine. However, I did hear last week that Triangle has picked up the warranty in the parts that their ink touches. Don't know if this is true but is what I heard.
Also..............You will have to make your own profiles. I have not seen/heard/found any profiles for this ink set.
I get good color from my inks.
