Maybe it’s because the machines are kinda rare and a little expensive, but old-school printmakers have a tendency to form co-ops. Somebody gets a press and some space, and soon there’s a group of working artists there. Ohio has a handful of places like this. At today’s Collective Ink gathering, Zygote Press plays host to a delegation from the southern part of the state. Artists from Columbus-based Phoenix Rising, Cincinnati’s Tiger Lily Press and the Dayton Print Cooperative get together for a reception and a panel discussion, moderated by Kent-based printmaker Michael Loderstedt. Works by artists from all of the shops will be on display. The reception starts at 1 p.m. at Zygote Press (1410 E. 30th St., 216.621.2900). The panel discussion is at 3:30 p.m. at Wooltex Gallery, in the Tower Press building (1900 Superior Ave.). Admission is free. — Michael Gill
