InkJet and Hotter Than The Sunp
Date: August 2004
In the Sunday, July 25, 2004 edition of The Columbian in
the business section I read an article. The name of the article was
"Think Ink". the full quote was " A high-end inkjet printer today is
precise enough to heat up ink to several times the temperature of the
sun, and shoot 36,000 droplets of ink through 512 nozzles each
second." How is that possible?
Ink jet nozzles can indeed shoot over ten thousand droplets of ink each
second. The temperature seems to be an exaggeration, as temperatures of
300-400C are adequate for bubble nucleation. Perhaps the article meant
several times the temperature to boil water. Although inkjet printers may
have many nozzles (for different colors and drop sizes) they are generally
not operated all at the same time.
