Measuring the Measurement Template Chart is the second sub-step of linearization following printing. During this process, the previously printed chart is measured using the measurement device specified in the profiling project. The measured values are compared with the reference values of the chart and form the basis for the subsequent Analyze Measurement Data sub-step, as well as for Create Linearization Profile - Settings Options.

The Measure dialog in the Linearization step is essentially divided into two areas:

• Preview of the Measurement Template Chart – this area displays a preview of the chart to be measured. Before measurement, only the left triangles representing the reference values [8] are displayed. After measurement, the measured values are compared with the reference values represented by the right triangle [9]. This allows immediate identification of whether the correct chart has been used or whether a measurement error has occured.
  When moving the mouse over a color patch, the patch address and the corresponding DeviceN values are displayed. In addition, both the reference and measured Lab values are shown. The preview can also be used for an additional visual check.
• Measurement Area – this area lists the configured measurements and is used to start the measurement process.

The following information and options are available in the Measure dialog:

• Measurement Information [1] – this section provides information about the measurement, including the Measurement Template Chart name, the selected measurement device, and the parameter set used.
• Preview Area [2] – this area displays a preview of the chart to be measured. To detect potential measurement errors, the measured values are compared with the reference values, which serve as an approximate color reference.
• Pages measured [3] – indicates the number of pages contained in the Measurement Template Chart. Clicking a page number loads the preview of the corresponding page and selects it for the measurement process. Once the measurement of a page has been completed, the corresponding page number is highlighted in green.
• Reset Measurement Data [4] – click this button to delete all measurements and completely reset the step.
• Measurement [5] – displays the current measurement, its status, as well as the timestamp and username. The following options are available for each measured page:
  • Delete Measurement Data [7] – click this button to delete the measurement of the selected page.
  • Download [6] – click this button to download the measurement of the selected page.
• Measure Page "x" [10] – click this button to start the measurement process for the currently selected page. The information is transmitted to the connected measurement device. During the measurement process, the measured color values for the corresponding patch are displayed. Once the measurement of the page has been completed, the system automatically switches to the next page of the chart. When all pages have been measured, the sub-step is completed.
