I don't know how many people print on coated stock with waterbased inks, especially any kind of hard or gloss finish, as it seems to me it might tend to repel the ink a bit. I'm just thinking out loud here. I've printed yard signs with a solvent ink and it goes pretty far.
As for ink usage, what screen mesh are you using? What kind of stock are you printing on? There are some art papers that are really porous that would soak up thin inks pretty quickly, especially with a design with large open areas. As for mesh, I wouldn't use anything coarser than a 230.
