WALTHAM, MA--(Marketwire - August 20, 2007) -

WHO:          Dr. John L. Marshall, Distinguished Scientist, Chemical
              Synthesis Group, ZINK Imaging

WHEN:         Tuesday, August 21, 2007
              2:20 - 2:40 p.m. EDT

WHERE:        234th American Chemical Society Annual Conference
              Symposium on Materials, Devices, and Switches
              Boston Convention & Exhibition Center

TOPIC:        Novel Fluoran Dyes For Direct Thermal Printing

DESCRIPTION:  In this presentation, Dr. Marshall will discuss how a new
              class of dye crystals enables a revolutionary thermal
              printing method that produces high-quality images quickly.

              He will also explain how the colorless crystals display vivid
              colors upon melting that persist when cool. As a result, the
              dye crystals will allow a new generation of mobile printers
              that can be embedded into printers, cameras, and other
              portable devices.
