we've used triangle for about 2 years, we have about 30 colors or so, it's ok....we are slowly switching to International Coatings as it prints way better, with less tack. Phoenix White and Batman Black are the bees knees though, super nice inks and we will continue to use those.....the colors we have, tri-flex series- are a little on the runny side, but they are manageable. a pretty decent all around ink, from what I remember it's on the cheaper side too..
