Procedure: Import for Spot Color for IT8 Files

Your calibration data record has only one spot color.

1.Click "Process Calibration" > open the calibration group > open the calibration data record > "Import".

2.The "Please Select a Source for Import" dialog displays. This is where you decide on the type of color data file that you will select later for import and on how the data will be imported.

Selection of type:

•"IT8 File with Measurement Data (.txt file), spot colors: filter (red, green, blue) with maximal density"

The density values for the (chromatic) spot color are determined with the RGB filter that pro­vides the maximum density.

•"IT8 File with Measurement Data (.txt-file), Spot colors: visual filter"

The density values for the (achromatic) spot color are determined with the visual filter.

•"IT8 File with Measurement Data (.txt file), Spectral density at wavelength with maximum absorption"

You should select this type if you wish to measure the spectral density but do not know the wavelength with the maximum density. In other words, you are measuring the color for the first time. After the import, the wavelength with maximum absorption is known and displays in the info box especially for repeat measurements.

Note: When you measure the spectral density of a color or import spectral density values, you should always use the same wavelength for repeat measurements or for a re-import of color data. The reason for this is that the wavelength defined with maximum absorption is the set reference point that enables you to compare your results.

•"IT8 File with Measurement Data (.txt file), Spectral density at wavelength xxx nm"

This type is suitable for repeat measurements. The wavelength xxx nm displays automatically in the list box because you made this wavelength known to the system as follows:

a) You already imported spectral density values at this wavelength and the wavelength was entered into the Info box.

b) You already measured spectral density values, for example, with a hand-held instrument and know the wavelength with maximum absorption. You entered the wavelength value manually into the Info box with "Info > Select Wavelength".

•"IT8 File with Measurement Data (.txt file), Spectral density at selectable wavelength"

Selection of this type lets you define a wavelength for which you would like to import spectral densities. After import, this wavelength is entered automatically into the Info box.

•Import of minispot data: The items you can select for minispot data are by analogy exactly like those items described above. Select the type of color data file you want and how the data will be imported and confirm your selection with "OK".

3.The "Select IT8 File for Import" dialog displays. Select your color data file in this dialog and con­firm with "Open".

4.The "Please Select a Wavelength" dialog displays if it is possible to select the wavelength. In this dialog, select your wavelength with maximum absorption and click "OK".

5.The "Choose a Color" dialog displays.

The names for spot colors that are used in the IT8 file do not necessarily match the color names from your job or the color names that you use in the data record. For that reason, you may have to assign color names in this dialog.

The "Choose a Color" dialog shows you the color names that are found in the IT8 file. In this dia­log, you must now select the color whose measured data will be imported for the spot color.

6.Click "OK". Import starts.
