ES3640e MFP Color Guide - 40
Understanding calibration
Although most users’ needs are met by the default calibration set,
the Fiery allows you to choose a calibration set to customize
calibration for specialized jobs.
Calibration allows you to:
• Maximize the color reproduction capabilities of the ES3640e
MFP.
• Ensure consistent color quality over time.
• Produce consistent output across Fiery servers.
• Achieve better color matches when reproducing spot colors,
such as PANTONE colors or other named color
systems.
• Optimize the Fiery for using ColorWise rendering styles (CRDs)
and CMYK simulations, and for using ICC profiles.
How calibration works
Success in obtaining satisfactory print quality from the Fiery
depends on many factors. Among the most important are
establishing and maintaining optimal toner densities. The density
is the measure of the light absorbed by a surface. By carefully
regulating toner densities, you obtain consistent printed color.
Even with a calibrated system, toner density is affected by service
settings, humidity, and temperature; density 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. These calibration curves are the
graphic equivalent of transfer functions, which are mathematical
descriptions of changes that will be made to the initial data.
Transfer functions are often graphed as input or output curves.
