2-4 Colour Calibration
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 colours.
To create a measurement file, print a page of colour patches. Then measure the patches
using either a colour measurement instrument connected to a computer on the
network or the ES3640e MFP's scanner. 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 page 1-13.

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 colour, 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.
Because printed output from the printer is very sensitive to changes in

temperature and humidity, the ES3640e MFP should not be installed near a window
or in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate
changes as well. It should be stored in a cool, dry, stable environment, and reams
should remain sealed until they are needed.
