Gravure
The gravure process is opposite that of letterpress in that the image area is
etched below the surface of the plate. The raised nonimage portion of the
plate is wiped clean of ink. Paper, pressed against the plate, lifts the ink out
of the etched areas.
Figure 1-2 shows the gravure process.
