There are many ways to calculate "Delta E", the numerical difference between two colors. This is often written as dE or ΔE. You can use the Preferences tab to set how Fiery Color Profiler Suite calculates dE.

1. In Fiery Color Profiler Suite, click Edit > Preferences.
2. Click one of these calculation methods in the dE Calculation Method list:

   • dE 76 - The standard CIE method. The color difference is the distance between the two colors, calculated in three-dimensional Lab color space.

   • dE 94 - A variant of CIELAB that CIE TC1-29 recommends as the color difference formula. For graphic arts applications, this method uses K1 = 0.045 and K2 = 0.015.

   • dE 2000 - A variant of CIELAB that CIE recommended in 2000. This method uses KL = KC = KH = 1.0.

   • dE CMC - The ratio of differences in lightness to chroma and to hue calculated using the ISO standard ISO 105-J03. Values for lightness and chroma weights are 1.0 for use with perceptibility data.

In Fiery Color Profiler Suite, you can create a Virtual Printer when a new calibration set and profile are created. This preference determines whether Fiery Color Profiler Suite will automatically create a Virtual Printer, ask if a Virtual Printer should be created when a profile and calibration are created, or never create a Virtual Printer.

1. In Fiery Color Profiler Suite, click Edit > Preferences.
2. On the General tab, set Create Virtual Printers.
   The choices are:

   • Ask - prompts the user to chose whether to create a Virtual Printer when creating a new calibration set and profile using Fiery Express Profiler or Fiery Printer Profiler modules.
   • Always - automatically creates a Virtual Printer when creating a new calibration set and profile using Fiery Express Profiler or Fiery Printer Profiler modules.
   • Never - does not automatically create a Virtual Printer when creating a new calibration set and profile using Fiery Express Profiler or Fiery Printer Profiler modules.

You can automatically create a CMYK calibration set and profile when a CMYK+ calibration set and profile is being created.

1. In Fiery Color Profiler Suite, click Edit > Preferences.
2. On the General tab, the Create an additional CMYK calibration set and profile from CMYK+ measurement data is selected by default. When saving a calibration set for a CMYK+ profile, a CMYK profile is also saved. The CMYK profile is saved with _CMYK added to your file name.
