Last weekend was the Photopolymer Workshop by AIGA Baltimore and Typecast Press. Mary Mashburn, of Typecast gave a tour of the shop while going over letterpress history. Then she showed the magic of creating a photopolymer plate. Each participant go to print their own Baltimore themed postcard design, and they then did a print exchange at the end. Everyone got to work on the two Vandercook presses, and a good time was had by all.
