Color Management
Maintaining copier consistency
The factors described below affect print device consistency, as well as color fidelity and
overall output quality.
overall output quality.
Paper stock and toner
The paper and toner used by your copier can greatly affect printed color. For best
results, use the supplies recommended by the manufacturer of the copier.
results, use the supplies recommended by the manufacturer of the copier.
Maintenance
Problems such as streaking and insufficient or excessive amounts of one or more toners
arise when a copier does not receive periodic maintenance or needs major repairs. In
addition to having it serviced regularly, monitor the condition of your copier by
making standard test prints at regular intervals. You can do this easily by printing the
Fiery Test Page. Save the prints and show them to the service technician whenever
output densities vary from the norm or other problems appear.

Print device gamut
Different color reproduction techniques have different color capabilities, or gamuts.
Color transparency films have comparatively large gamuts, as do color monitors. The
color gamut that can be produced using process inks or CMYK toners on paper is
smaller. This is why some colors that can be displayed on a color monitor, especially
bright saturated colors, cannot be reproduced exactly by your Fiery copier—nor, for
that matter, can they be reproduced on a press using process colors. Moreover, different
print devices have different gamuts—some colors that your copier can produce cannot
be reproduced on an offset press, and vice versa. The following illustration provides a
graphical representation of this concept.
