After measurement data is available, the Summary window displays a summary of information about the measurements and the conditions used to create them. The dE (sometimes referred to as ΔE or Delta E) values summarize the variation in measurements of the same color.

If a dE value is displayed in red, it is because the variation appears to be significant. The variation does not necessarily indicate an error, but consider these values for realistic expectations. Your profile cannot be any more accurate than what has been measured.

You may want to examine the printed profiler patches for physical blemishes or consider remeasuring the patch pages.

You can also check for potential problems with the measurement data by viewing the color space that the measurements represent in Profile Inspector.
