In this article, you will learn
- how measurement data can be analyzed,
- which analysis options are available,
- which settings can be configured.
1. Introduction
Analyze is an optional substep available at multiple steps of the profiling project. The purpose of this substep is to visually evaluate the measurement data collected during measurement, before the respective profile is created. The Analyze dialog has largely the same structure in every step. Depending on the specific step, additional, step-specific analysis methods are also available.
Note that the Analyze substep is optional. If no visual evaluation of the measurement data is required, you can proceed directly to the next step for calculating the profile.
2. Setting Options
The Analyze dialog is divided into several tabs. The following tabs are available in every step:
- Measurement Result – this tab displays the measurement data of a chart – measured values and target values – page by page.
- Color Axes – this tab displays the measurement data in a 2D or 3D view.
- Data – this tab provides the measured data in ISO 28178 format.
Depending on the respective step, additional tabs may also be available – for example, the Curves tab in the Linearization step, or the Spider View tab in the Characterization step.
2.1. "Measurement Result" Tab
The Measurement Result tab displays the measured measurement template chart. Each color patch is divided into two triangles. The left triangle shows the target value, the right triangle shows the measured actual value. This makes it possible to identify deviations between the target and actual values at a glance.
Figure 1: The Measurement Result tab of the Analyze substep.
The following information and options are available in the Measurement Result tab:
- Color Patches Total [1] – displays the total number of measured color patches.
- Quick Filters [2] – use the quick filters to limit the measurement template chart view to the desired information. The following quick filters are available:
- Primary Colors – displays only color patches consisting of a single primary color.
- Secondary Colors – displays only color patches consisting of a mixture of two primary colors, i.e., a secondary color.
- 100% Color Patches – displays only the color patches of the primary colors with a tone value of 100%.
- Paper White – displays only color patches with a total ink coverage of 0%, i.e., paper white.
- K 100% – displays only the color patch for 100% black.
- Individual Color Channels – click the respective color indicator to show or hide the corresponding color channel.
- Preview Area [3] – displays a preview of the chart that has already been measured. Moving the mouse pointer over a color patch shows the position of the color patch – i.e., A1, A2, etc. – as well as the associated DeviceN, reference, and measured Lab values. The preview allows you visually check the measurement and immediately see whether it is consistent or not.
- Measurement Chart Page Count [4] – shows the total number of pages of the respective measurement chart, as well as the page the user is currently on.
- Show and Hide Filters [5] – click this button to show or hide the quick filters.
- Pagination [6] – allows you to navigate between the pages of the measurement chart. Depending on your current position, you can move to the next, last, previous, or first page of the chart – depending on the respective page count of the measurement chart.
2.2. "Color Axes" Tab
The Color Axes tab visualizes the measurement data in a 2D or 3D view in the L*a*b* color space. The view can be displayed either in 2D or 3D. The following information and options are available in this view:
- Quick Filters [7] – use the quick filters to limit the visualization to the desired information. The following quick filters are available:
- Primary Colors – displays only the primary colors.
- Secondary Colors – displays only the secondary colors, i.e., the mixtures of two primary colors.
- 100% Color Patches – displays only the 100% tone values of the primary colors.
- Paper White – displays only paper white.
- K 100% – displays only 100% black.
- Individual Color Channels – click the respective checkbox to show or hide the corresponding color channel.
- 2D / 3D [8] – switches between the 2D and 3D view.

What can you read from the chart?
This view allows you to assess whether the light and dark inks are located on the same color axes and whether the color axes consistently move outward.
- Light / Dark Inks – the better the color axes of the light and dark inks align with each other, the smoother the transition between the two colors can be.
- Color axes curving inward – if the color axes curve inward along their path, this can, in most cases, lead to a chroma limitation of the primary color.
2.3. "Data" Tab
The Data tab displays the content of the generated measurement file in ISO 28178 format. The following information and options are available in this tab:
- Download Measurement File [9] – click this button to download the measurement file.
- Measurement File Preview [10] – the preview displays the complete content of the measurement file.

3. Step-Specific Analysis Methods
In addition to the analysis options available across multiple steps, further step-specific analysis methods are available, depending on the respective step of the profiling project. These are described in the following sections.
3.1. Curves
In the Linearization step, the Curves tab is additionally available. This tab displays the measurement curves of the individual color channels in a chart. The Curves tab is divided into four additional tabs:
- Tone Values – displays the tone-value-based correction curves of the individual color channels.
- Chroma Values – displays the chroma values of the measured color tones of the individual color channels.
- Lightness – displays the lightness values of the measured colors. This generally applies only to the black channel.
- Reference Color Space – displays the ∆E₀₀ value of the measured colors relative to the reference color space.
Tone Values
The Tone Values tab displays the corrected SCTV values (Spot Color Tone Value) of each color channel relative to the input value, in percent, against the measurement data. The horizontal axis shows the input value, while the vertical axis shows the SCTV value. A linear curve corresponds to the ideal behavior of a linearized printing system.
The following options are available in the Tone Values tab:
- Show or Hide a Color Channel [11] – click the checkbox of the respective color channel to show or hide it.
- Show or Hide all Color Channels [12] – click this checkbox to show or hide all color channels.
Figure 4: The Curves tab in the Tone Values view of the Analyze substep.
Chroma Values
The Chroma Values tab displays the chroma values (color saturation or chroma) of the primary colors relative to the input value. Since the black channel has no saturation, only the Cyan, Magenta, and Yellow channels are available. The Show Maximum Values option [15] can be used to display a vertical marker line for each channel at the point where the maximum chroma value is reached.
The following options are available in the Chroma Values view:
- Show or hide a color channel [13] – click the checkbox of the respective color channel to show or hide it.
- Show or hide all color channels [14] – click this checkbox to show or hide all color channels.
- Show Maximum Values [15] – enable this option to display a vertical marker line for each channel at the point where the maximum chroma value is reached.
Figure 5: The Curves tab in the Chroma Values view of the Analyze substep.
Lightness
The Lightness tab displays the lightness value (L*) of the black channel relative to the input value. This curve type is only available for the black channel.
The following options are available in the Lightness tab:
- Show or Hide the Color Channel [16] – click the checkbox of the black channel to show or hide it.
- Display lowest ∆E [17] – enable this option to display a vertical marker line for the black channel at the point where the lowest ∆E value is reached.

Reference Color Space
The Reference Color Space tab displays the ∆E₀₀ value of each color channel relative to the input value. This visualizes the colorimetric deviation of the measured colors from the selected reference color space.
The following options are available in the Reference Color Space tab:
- Show or Hide a Color Channel [18] – click the checkbox of the respective color channel to show or hide it.
- Show or Hide all Color Channels [19] – click this checkbox to show or hide all color channels.
- Display lowest ∆E [20] – enable this option to display a vertical marker line for each channel at the point where the lowest ∆E₀₀ value was measured.

3.2. Spider View
In the Spider View tab – available only in the Characterization step – displays the measurement data in a two-dimensional a*b* diagram. This view provides a quick way to assess how evenly the chroma curves of the individual color channels progress and how the measurement values behave in the area of the gray axis, i.e., near the achromatic point. This assessment is particularly relevant for G7 linearization, since its goal is to achieve a neutral gray balance.
The following options are available in the Spider View tab:
- Show Secondaries [22] – enable this option to additionally display the curves of the secondary colors, i.e., the mixtures of two primary colors, in addition to the primary colors.
- Project Gamut [21] – enable this option to display the light gray rings that connect the curves of the individual color channels in the diagram.
