i've been having the same bad luck lately, as well. Was running bordeaux inks for the past year and recently started overspraying on all my prints... parts replacement, cleanings, etc. nothing helped and every service tech wanted to blame the inks. So I swapped back to OEM, and it did help... but I'm thinking the flush may have been the trick.
I still overspray, however, but only when I run my Onyx software to print.... ijdk why, but I've confirmed it must be a software/profile issue due to printing the same files on ily-Flexi software my friend has on his laptop. ALL MY PRINTS ARE COMMING OUT CLEAN!!! what the hell?
Best of luck to ya, but don't be so quick to blame the inks. I know plenty of people that run Triangle and they are very happy with it. Could also be a bad batch of inks, happens with all the brands... even OEM. I will most likely be sticking with OEM for a while, especially since my printer runs in a smaller space shared by our sticker girl... who HATES the smell of 3rd party inks. Since the swap back to OEM, no complaints of the solvent smell.
