My walls are covered with digital images that
I??™ve printed, matted, and framed (see Figure 17-3). No one can tell the difference, or even
particularly cares about the difference between film and digital prints anymore.
Dye-Sublimation Printers
A small but important segment of the printer market is occupied by dye-sublimation printers
(also called dye subs for short). Look inside a dye-sublimation printer, and you??™ll see a long
roll of transparent film that appears to be sheets of red-, blue-, yellow-, and gray-colored

cellophane (see a dye-sub printer and cartridge in Figure 17-4). The film is composed of solid
dyes corresponding to the four basic colors used in printing: cyan, magenta, yellow, and black
(CMYK). The print head heats as it passes over the film, causing the dyes to vaporize and
permeate the glossy surface of the paper before they return to solid form. Because the dye gets
absorbed and goes just below the surface of the paper, the process is called dye sublimation.
Because the color infuses the paper, it??™s also less vulnerable to fading and distortion over
time.
