Introduction

Patricia O Cohn is a notable inventor based in Redwood City, CA, who has made significant contributions to the field of ink jet printing technology. With a total of 2 patents, her work has advanced the methods and apparatus used in image recording.

Latest Patents

Cohn's latest patents include a method and apparatus for ink jet printing. This innovative image recording method involves heating a sublimable dye to produce dye vapor, which is then jetted from a nozzle toward a recording member. A gas stream is utilized to pass across the dye vapor, effectively removing any cooled dye vapor or fine particles from the vicinity of the recording member. This process enhances the quality of the picture image formed. Another patent focuses on an image recording method where dye vapor generated by heating sublimable dye is mixed with condensable vapor. This mixed vapor is jetted from a nozzle with controlled amounts, allowing for high-speed image recording while maintaining low heating temperatures for the sublimable dye. This technique results in smaller picture elements and prevents spreading, thus enabling high-resolution recordings.
