Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I'm in Austin so I have used most of Kevin's inks. I like them, though not as much as the Rio inks we currently use. I tested a quart of the matte black, and it's definitely matte, but it's kind of a dark gray vs the jet black we prefer. I don't actually have a favorite black, but we print with the triangle batman black usually, mainly because it's good for transfers and direct printing and it prints really nicely.
