Nonimpact
Thermal transfer, ink jet, laser, wax, continuous tone die sublimation, and
printer types
color phase change are nonimpact printers that you may find in a Navy shop.
THERMAL TRANSFER PRINTERS :
ink dies from a heated printing element
Thermal transfer printers use wax or
to transfer an image to a page.
INK JET PRINTERS: Ink jet printers spray electrically charged ink through
tiny nozzles in the printing element. The ink passes through an electrically
charged field that forms the image in matrix form. These printers offer very
high-quality resolution and print up to 300 cps.
LASER PRINTERS: A laser printer directs a beam of light that electrically
charges an image on a photosensitive drum. Toner attracts and adheres to the
dots on the drum and a heating element fixes the image on the paper. These
printers can print in excess of 20,000 lines per minute.
WAX PRINTERS: Wax printers use a ribbon of thin transparent wax.
Ribbons are available in color and are useful for transparencies.
CONTINUOUS TONE DIE SUBLIMATION: Continuous tone die
sublimation uses color dies on a plastic film for image transfer. This is a
thermal transfer and requires specially coated papers.
COLOR PHASE CHANGE: A color phase change uses Pantone certified
colors in a wax medium. Like continuous tone die sublimation, this is a
thermal transfer, but it does not require specially coated paper.
