Xerox DocuColor 12 Printer with Fiery X12 전단

Even with a calibrated system, toner density is affected by service settings, humidity, 
and temperature; it also tends to drift over time. Regular measurement detects day-to-
day variations in densities, and calibration corrects for them.

Calibration works by creating calibration curves on the Fiery that compensate for the 
difference between actual (measured) and desired (target) density values. 

Calibration curves are the graphic equivalent of transfer functions, which are 
mathematical descriptions of changes that will be made to the data you start with. 
Transfer functions are often graphed as input or output curves.

The Fiery generates calibration curves after comparing measured values to the final 
target values for each of the four toner colors. The target values are based on the output 
profile specified.

Measurement files contain numerical values that correspond to the toner density 
produced by the copier when it prints solid cyan, magenta, yellow, and black, and 
graduated tints of those colors.

To create a measurement file, first print a page of color patches from 
ColorWise Pro Tools or from the Control Panel to the copier. Then measure the 
patches using either an X-Rite DTP32 densitometer connected to a computer on the 
network or the copier’s scanner. The new measurements are automatically downloaded 
to the Fiery.

Output profiles and calibration sets define desired calibration results. One or more 
output profiles and one or more calibration sets are provided with the Fiery. When you 
calibrate the Fiery, you can select the calibration set that corresponds to the typical 
printing jobs at your site. This same calibration set can be associated with one or more 
output profiles. (For more information on output profiles, see page 1-9.)
