View measurement results
After you measure a calibration page or import measurements, the measurement results are ready to be applied.
Applying (saving) the measurement data overwrites the existing data. For color data, you can view the measurement
data in a graph to check the data before applying it.
Measurement results are shown as a set of density curves for C, M, Y, and K. For comparison, the calibration target
data is also shown as a set of thicker density curves in the same graph, and the maximum density values are
compared numerically.

To hide or show curves, click the icon next to the appropriate label:
• Measured - Hides or shows the measured density curves.
• Target - Hides or shows the target density curves.
• Cyan, Magenta, Yellow, or Black - Hides or shows the measured and target density curves for the specific
colorant.
Visual difference
For color measurements, the visual difference percentage is a convenient way to evaluate the calibration accuracy.
Measurement data is displayed in paper relative density units (Status T). The Fiery Server calculates the visual
difference percentage using the Murray-Davies formula, which takes into account the exponential nature of density
measurements.
If the measured maximum density is less than the target maximum density, it means that the printer is currently
performing lower than expected using this calibration setting. A printed output at 100% of this colorant does not
result in the maximum density that this type of printer is expected to print. This situation is acceptable in many
proofing situations, because simulated CMYK color spaces typically do not require the maximum density that the
printer is capable of.
If the measured maximum density is more than the target maximum density, it means that the printer is currently
performing higher than expected using this calibration setting. To meet the calibration target, the Fiery Server does
not need to specify 100% of the colorant. However, the full gamut of the printer is not being used.
An application such as Adobe Photoshop uses units of percentage from 0% (paper white) to 100% (maximum
density). Assuming the output profile used in Adobe Photoshop matches the calibrated state of the Fiery Server, a
visual difference of -5% for cyan means that the printer cannot produce the cyan color values specified in Adobe
Photoshop between 95% and 100%. A visual difference of +5% for cyan means that the printer can produce all the
cyan color values specified in Adobe Photoshop, and could produce up to 5% denser cyan values as well.
