The Baltimore Museum of Art has used the Pachyderm multimedia authoring tool to develop this interactive online presentation based on a popular exhibition. There are four sections, two historical: The Apocalypses of Dürer and Redon, and The Prints of Hogarth and Raftery: A Comparison. The other two sections invite users to explore 20th and 21st century printmaking, using the works of artists such as Ed Ruscha, Daniel Heyman, Roy Lichtenstein, and Sherrie Levine, who work in series and editions, and confront current issues. In Meltdown, Sherrie Levine's series, the artist used historical paintings as inspiration, scanning the works and using computer software to reduce each one to 12 colors. She then printed the colors as 12-square grids using one of the oldest printing techniques, the woodcut. The final section highlights Printmaking Techniques, from stencils and woodcuts to lithography.
