Overview
This guide introduces the usage of the Barbieri SpectroPad portable spectrophotometer in combination with neoStampa Calibration Wizard. The full process of Calibration Wizard is described in the Calibration Wizard knowledge base.
Device Configuration
Driver Connection
The SpectroPAD will be installed automatically when is connected to the computer and switched on. If you have trouble with the automated installation of the driver, follow the description below.
Connect the Spectropad to the computer using the supplied USB cable and switch the Spectropad on.
Open Control Panel | Device Manager. In the list, open Other Devices and select SpectroPad.
Click right and select Update Driver Software…
From the new window chose to Browse my computer for driver software to locate the driver.
Browse to and select C:\Program Files\Inedit\neoStampa 10\required\Barbieri Spectro USB Driver\WIN-VERSION. Click on Next to continue.
The installation of the driver starts and when is completed, click on Close.
Configuration in Calibration Wizard
Start Calibration Wizard. Open Configuration… from the bottom of the window.
Select the Barbieri device from the list.
Select Illumination (D65 or D50) and Observer (2 or 10).
UV-Filter
If you need to use UV-Filter in Scan mode, enable the option from the Configuration window.
If you need to use UV-Filter in Spot mode, you need to choose the option from the device. From the display open Spot Mode and select the Illumination M2 (excl UV) option.
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.
Place the device over the printed chart. For accurate measurements, the device must be calibrated before use. The measuring head is equipped with a switch that allows manual insertion of the white reference. The calibration is required with each new printed chart.
When this switch is operated, the instrument will automatically detect this and inform you that it is being calibrated. Release the switch when calibration is terminated.
Press the Measure… button to read the chart. It opens the measurement dialog and is ready to be measured.
Put the device centered on a printed chart. Position the instrument on the center of the bottom chart line by centering the two laser beams.
When this is done, keep the device and move the measuring head to the beginning of the chart row.
Start the measurement. The device supports Bi-directional measurements. Lines can be measured in direction from left to right and from right to left.
The device will recognize the current position and when the end of the line has reached. Make sure the speed indicator is in the green range during measurement, as this will allow the most exact measurements. If your measurement is too fast, it responds with a message. Press on OK and repeat to measure the same line once again.
When the first line is measured, move the device to the next line and keep measuring, until you have measured all lines in the chart.
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 1530 patches contains 6 pages of targets.
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.
Put the device centered on a printed chart. Position the instrument on the center of the bottom chart line by centering the two laser beams.
When this is done, keep the device and move the measuring head to the beginning of the chart row.
