2-41 Understanding calibration
ES3640e MFP Color Guide - 41
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.
Measurements
Measurement files contain numerical values that correspond to
the toner density produced by the printer when it prints solid
cyan, magenta, yellow, and black, and graduated tints of those
colors.
To create a measurement file, print a page of color patches. Then
measure the patches using a color measurement instrument
connected to a computer on the network. The new measurements
are automatically downloaded to the Fiery.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration
results. One or more output profiles and calibration sets are
provided with the Fiery. When you calibrate the Fiery, 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
.
Scheduling calibration
In general, you should calibrate the Fiery at least once a day,
depending on the volume of print jobs. If it is very important to
maintain consistent color, or if the printer is subject to wide
fluctuations in temperature or humidity, calibrate every few hours.
For optimal performance, calibrate whenever there is a noticeable
change in print quality.
If you need to split a print job into two or more batches to be
printed at different times, it is especially important to calibrate
before printing each batch. You should also calibrate the Fiery
after printer maintenance.
