Xerox DocuColor 12 Printer with Fiery X12 Leaflet

The factors described below affect print device consistency, as well as color fidelity and 
overall output quality.

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.

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.

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.
