Measuring Test Charts
All test charts created with GMG OpenColor can also be measured within the application.
How to measure a test chart
You will need to switch to OpenColor Test Chart.
- From the Source list on the left, select OpenColor Test Chart.
- Select the test chart you want to measure from the Test Chart list.
Each test chart page is shown separately in the Measurement Result group. - If you are using an X-Rite measuring device in scan mode, you can add a check mark to the Plausibility Check box to use this X-Rite feature to detect faulty scans. If the plausibility check failed, you will be notified.
- If you are using an automated chart reader, insert the first page into the measuring device.
- On the Tools & Action panel, click Start Measurement.
The measuring device will be initiated for measuring. If manual interaction is required such as white calibration, you will be notified by a message. - Follow the instructions to prepare the measurement.
When the measuring device is ready, the Measurement status changes to Measuring.... - Proceed with the measurement and repeat this procedure for all pages.
Measuring a test chart.
You will see a preview of the selected test chart. The preview shows if gaps have been deactivated (1). You can measure a test chart that has been mirrored during printing (2). If a test chart has been resized during the printing process, for example, because of RIP or paper feed settings, you can use the Resize feature (3) to measure it. You can measure the dimensions of one of the printed color patches and enter the values into the Patch Size boxes (4).
Following the measurement, you need to create a characterization from the measurement data (Tools > Create Characterization).
