Process Color, Continued
If the color in the resulting print is simple to separate and appears without
modulation, it is called flat color. Gradations of tone require the use of
shading sheets and are photographed as line art. Spot color and fake color
are examples of flat color printing processes.
Spot color is a process used when only a small portion of an image requires
color. The printer separates color areas by reading instructions attached to
the original artwork on an overlay. The DM does not have to separate color
on another piece of art. On complicated drawings, the DM creates overlays
for each color, registers them to the master, and indicates desired ink color.
Fake color, or pre-separated color, also uses overlays to indicate colored
areas on line art or continuous-tone art. Place an overlay on the art and
define the outlines of the image on the overlay. The printer will strip the
separations into color panels and make separate color plates.
