PrintMaster is a Design & Print software package. Released originally in 1986. Company was sued for its similarity to The Print Shop product and was eventually acquired and sold as another software title. Products were bought and sold, partnered with, many times by MicroLogic, Mindscape, The Learning Company, Mattel, ExpressIt, Riverdeep, Broderbund and currently Encore systems. Released in Windows and Macintosh compatible versions.

Early versions of the PrintMaster desktop publishing software stored clip art in a pair of files: an .SDR file containing names, and an .SHP file containing graphics. The file formats are fairly similar to those used by The Print Shop.

A related(?) program named NewsMaster also used .SDR and .SHP files, and added an .SDX index file.
