Some terms to start off with:
•chromatic colors: colors that are measured either with one of the RGB filters or in a spectral scan.
•achromatic colors: colors in blacks and grays that are measured with a visual filter.
•visual filter: This filter simulates approximately the way the human eye perceives lightness and is used for determining the density value of blacks and grays.
•SCTV: Spot Color Tone Values; the calculation of tonal values based on SCTV (see ISO 20654 - Spot Color Tone Value) is supported during the import of color data files for process calibration.
The following types of color data files can be imported:
•IT8 files: Format for color data files.
•CPC24 Image Control color data files: Import feature for older systems with Prinect Image Control.
•Color data files for Delta or Harmony systems.
Before you import files, you must decide on the type of color data file and, if applicable, on how the data will be imported. You will find a description of what types of file are available for IT8 files and how to select them in the procedures described below.
The menus that display for the import of color data vary, depending on the colors that are in your calibration data record:
•Only process colors
•Multiple colors
•Only one spot color
For that reason, you will find an overview of the menu prompt in these three cases below. This is followed by an example of how to proceed in each of these cases.
