Performance
Start the Calibration as usual until the point to measure printed Single Ink Cut chart, Linearization chart and Printer profiling target chart.
Single Ink Cut/Linearization chart measurement
Print the charts as Calibration Wizard requires in the manual.
Before starting to use the device, it must be calibrated. The device has an integrated calibration plaque and will calibrate automatically when required. The calibration plaque is located directly below the optics when the device is in the open position (not locked).
Click on Calibrate button to make the action and follow the steps on the device display. Locate the device on a flat surface and tap the START button on the display. It will display a countdown screen and then perform the calibration.
Press the Measure… button to read the chart. It opens the measurement dialog and is ready to be measured.
Position the ruler with the device on the media above the first patch of row #1 of your chart. Lower the device to the target base and hold steady until the measurement is complete.
In one continuous motion, roll the device across the color bar without stopping. Use the black scribe line on the edge of the chassis to align the device during the scan, and view the device display for scan speed indication. One of the circles appears on the device to provide feedback on your scanning speed.
Scanning the color bar too fast or too slow for an extended period of time may produce inaccurate measurement results. Always try to maintain a steady scanning speed with the white circle showing as much as possible for the best results.
When the last patch is passed release the device.
Position the ruler with the device in front of the next row of your test chart and measure the next row.
Simultaneously in Calibration Wizard, the lines are completed with each measures line. When done, click on OK in the measurement dialog and continue with the calibration until you reach the printed profiler target chart.
Profiler target chart measurement
Print the charts as Calibration Wizard requires in the manual. Once again repeat the device calibration as described above.
Using the large target chart of 1516 patches.
Press the Measure… button to read the chart. It opens the measurement dialog and is ready to be measured.
Remember to calibrate the device as described above before starting the measurement.
As seen above, position the ruler with the device on the media above the first patch of row #1 of your chart. Lower the device to the target base and hold steady until the measurement is complete. When the last patch is passed release the device.
Simultaneously in Calibration Wizard, the lines are completed with each measures line. When done, click on OK in the measurement dialog and finish the calibration.
