After almost becoming obsolete, letterpress is now enjoying a revival, as much as an art form as a way of publishing independently. Expertly typeset artists' books, pamphlets, zines, posters, stationery, and limited editions of books run off rescued presses. It is labour-intensive, but as this week's printers knew, "there's definitely a romance about it", as Claire Battershill says. (Poster by Elisa Tersigni.)
