Overview
This guide introduces the usage of the Barbieri SpectroLFPqb spectrophotometer in combination with the neoStampa Delta Calibration Wizard. The full process of Calibration Wizard is described in the Calibration Wizard knowledge base.
This device is not supported on neoStampa for spot measurements whether with Color chart or Color replacement tools.
Full support requires neoStampa version 10.0.5 or later.
Driver installation
Driver installation requires running an executable file located in the following directory, C:\Program Files\Inedit\neoStampa 10\required\Barbieri Spectro USB Driver. Run it to open the driver set-up wizard.
Device Configuration
Open Calibration Wizard and click on Configure button at the bottom of the application interface and select Barbieri SpectroLFP from the Device list.
Check Transparency for backlit samples.
Unlike other spectrophotometers, the SpectroLFP UV-cut filter cannot be tested on the Settings dialog as it is enabled by selecting M2 measurements on the device interface.
Performance
The Barbieri target format is selected automatically when it comes to printing it.
Place the chart on the sample holder and press the ON/OFF button to turn the electrostatics on. This will add extra grip between the sample and the holder.
Positioning and Parameters
When opening the Calibration Wizard Measure panel and starting measurements, firstly you will be asked to set up the target positioning and the measuring parameters.
The device supports three positioning modes, Camera, Line, and Manual, being Camera the default one. If the device failed at positioning charts with any of the automatic modes, it would try with the next one. Bear in mind that Automatic Camera mode will be disabled for the measurement of the linearization chart and the default mode will be Automatic Line.
As for Parameters, these depend on the printing and substrate features of the sample, which could require setting combinations of parameters different from the default.
- Aperture: It defines the lens aperture for better color capture. Profiling target patch size is closely related to the lens aperture, as the wider this is, the larger the patches should be. Choose the appropriate target according to the aperture required.
- Mode: It defines the height and displacement of the spectrophotometer while measuring. Up-down is the most accurate mode, even though is the slowest mode.
- Average: It defines the number of shots for each swatch measurement according to the accuracy required.
Measurements as such would start when clicking on Ok.
Profiling targets
As well as the linearization charts, those for profiling come with the Barbieri format automatically. Select one according to the device lens aperture set on Configuration. The difference between those ones that show "RGB" at the beginning or at the end is as follows: first ones are loaded as a single print-out whereas page selection could be required to print second ones depending on their size.
