October 5-7, 2018: I taught a 2.5 day intensive Century Plate Lithography Part 2 class at EFA-Robert Blackburn Printmaking Workshop in New York City. In this whirlwind weekend workshop we re-visited techniques covered in Part 1 and covered graining for and coating plates with Posi-Coat (the first non-toxic, positive-working photo emulsion), exposed test plates, learned how to create tusche washes and and etch and process them with non-toxic materials and re-visited proofing on RBPMW's Charles Brand litho press.
