Explanation of Figures

(1) File selection

Click to load validation results saved as a PQX file.

Use and to successively load all files with the currently selected type available in the current folder.

Note:

Validation results are only displayed if you load a single PQX file. If you select multiple files and PQX files are among them, the report will include the CxF/X-4 color definitions stored in these PQX files, but validations results will be ignored. The report will therefore be as explained in section Understanding Reports on CxF/X-4 Colors.

(2) Color and tint selection

Select a CxF/X-4 color definition from the list at the top or by clicking on a color box displayed next to the list.

If various tint values are defined for this color, select a tint value from the list .

The spectral data and colorimetric data for the selected color and tint value will appear in the dialog.

(3) Spectral reflectance data for target and actual values

• Left: Wavelength of incident light in nanometers.

• Center: Portion of reflected light defined by CxF/X-4 data ( target values).

• Right: Portion of reflected light that was measured ( actual values).

(4) Spectral reflectance curves for target and actual values

• X-axis: Wavelength of incident light in nanometers.

• Y-axis: Portion of reflected light (1,0 = 100%)

• Curves for CxF/X-4 data ( target values) and measurement ()

• Curve points: Nanometer values listed in table (3)

(5) CIE Lab charts

Colorimetric values of table (6a) plotted as:

• Hue (a*b*) chart

• Lightness (L*) chart

Two points: CxF/X-4 data; measurement

(6a) Colorimetric data

For CxF/X-4 data and measurement, calculated from spectral data:

• CIE L*a*b* (lightness, red/green hue, blue/yellow hue)

• CIE L*C*h° (lightness, chromaticity, hue angle)

Validation result:

• Color deviation with pass/fail indication (red/green background)

• Tolerance value

(6b) Metamerism index (MI)

Calculated from the deviations between CxF/X-4 color and measured color viewed under different illuminants:

• MI values with pass/fail indication (red/green background)

• Tolerance value

• MI validation is successful if all MI values are within this tolerance limit (green)

(7) Overall pass/fail indication

The icon indicates the overall validation result:

	Passed: All validation results are OK (both the dE value and all MI values)
	Failed: At least one validation result is not OK (delta E, one or more MI values, or both)

(8) Ink properties

Specifications of ink properties intended for ink suppliers, calculated from spectral data measurements.

Opacity	Ratio of lightness values of 100% tint printed on substrate and 100% tint printed on black. 0% means: Ink is invisible when printed on black. 100% means: Ink is completely opaque.
Spectral Density	Ink density of 100% tint printed on substrate.
Dot gain at 50%	Dot gain value for a 50% tint, derived from the TVI value. See also glossary.
Print contrast at 70%	Ratio of ink densities for 70% and 100% tints calculated as follows: (1–D70/D100)*100 0% means: 70% tint has same density as 100% tint. 100% means: 70% tint is invisible.

(9) CxF/X-4 metadata

Information that identifies the spot color and how it was measured, stored in the metadata of the CxF/X-4 file.

(10) Buttons

The button on the left allows you to switch between the following:

• CxF/X-4 data

  Report on CxF/X-4 colors.

• Spectral data

  Spectral curves for all tint values of selected CxF/X-4 color printed on substrate. Large chart that fills the entire window area.

• Certification

  Validation report.

  Setting only available if validation measurements were made for selected CxF/X-4 colors
