San Francisco Center for the Book  Rhode Island Street, between 16th and 17th St., San Francisco

With roots going back hundreds of years, relief printing -- a process where a protruding surface is inked and brought into contact with paper - is one of the oldest methods of printing illustrations in books.

During the Roadworks Steamroller Printing Festival we celebrate this interesting fact of book arts history in the biggest, over-the-top, spectacular way we can think of, by printing linocuts using a 7-ton 1924 Buffalo Springfield steamroller and linocuts using a 12-ton 1916 Kelly Springfield steamroller -- both provided by Roots of Motive Power - combined with the road surface of Rhode Island Street as a humongous makeshift printing press. In this way a team of featured artists, printers and steamroller operators create large-scale Featured Artist prints and smaller Personal Prints Artists prints, during the Festival.
