Measuring with the Barbieri Spectro LFP qb
Step 1: Select the device from the Selection drop-down list.
Step 2: Click Connect.
Once the device is connected, the Barbieri Setup Wizard of the LFP qb opens:

Positioning
Position the head of the device on the upper left corner of the chart, see screenshot.
Use the manual positioning on the right side to position the head exactly above the upper left corner using the arrow keys or by entering the x/y coordinates. The measuring head should then be positioned on the outermost corner of the marked patch.
Automatic positioning by using the camera
When using automatic positioning by camera, a photo of the entire chart is taken and searched for the marker lines at the borders. The auto positioning is therefore only possible if the chart has the required borders and markers.
Use the manual positioning on the right side or the automatic positioning to position the head exactly.
Select the Use auto positioning checkbox and click Next. The complete chart is now measured.
Note: The camera must be connected in order to use automatic positioning by camera. If the automatic positioning by camera does not work, the system switches back to the automatic positioning without camera.
Automatic positioning without camera
In automatic positioning without a camera, the measuring head searches for the marker lines at the border. Auto positioning is therefore only possible if the chart has the required borders and markings.
Select the Use auto positioning checkbox and click Next. The complete chart is now measured.
Manual input options for positioning
The four arrows change the position of the measuring head (left, right, up, down). Raise and lower the head with the double arrow in the center.
Tip: Change the position of the head with the corresponding arrow keys on your keyboard.
Steps: Indicates the units that the measuring head covers when an arrow is clicked.
Position: Change the position of the head by entering x/y coordinates.

Once you are finished, click Next to specify the upper right corner of the chart.

Confirm with Next.
On the last page, enter the position of the lower right corner and confirm with Next.

Settings

Chart options
Rows on (first) page: Enter the number of rows on the test chart page. If the test chart consists of multiple pages, enter the number of rows on the first page.
Horizontal patch gap: Specify the height of the horizontal patch separator in mm.
Vertical patch gap: Specify the height of the vertical patch separator in mm.
Measure options
Measurement condition: M0, M1, M2, M3.
Aperture: Choose between Default, 2, 6, 8 or manual.
Measure Mode:
- Fast (default)
Fast measuring mode is the default mode of the Spectro LFP. In this mode the measuring head lies on the target and the
surface is scanned.
- Up-Down
In up-down mode the measuring head of the instrument moves up
and down between each measurement. Use this mode for sensitive
materials to avoid any scratches on the surface of the target.
- Contactless
The contactless mode is similar to the above fast mode with a
difference that the measuring head does not touch the surface
of the target. This measuring mode is suitable for sticky and
sensitive materials.
Note: The fast measure mode Fast (default) always uses the same amount of
light and can therefore measure dark and bright samples equally fast. However, the disadvantage is that dark samples in particular are not recorded with sufficient accuracy. The single contact measure mode Up-Down is advantageous here, because
the required amount of light can be individually adjusted for each colour patch. This leads to a better differentiation, especially with dark colors.
Start: Starts the measurement of the chart.
Multipage test charts
Manual positioning
If the test chart has multiple pages, a message appears after measuring a page prompting to place the next page on the table:

- Place the next test chart page on the table.
- Recalibrate the table and use the manual controls as described above to indicate two corners of the chart. The third corner is calculated automatically.
- Click Start to measure the next page.
Important: If the second page was placed EXACTLY where the first page was, you can continue without recalibrating. The previously set coordinates will then be used again.
Creating charts with Barbieri gateway and measuring using ColorAnt
To create ColorLogic charts within Barbieri Gateway’s chart generator, including the auto positioning feature, follow the procedure below:
Copy the ColorLogic charts to the user directory: Myuser>Documents>Barbieri>Gateway
Start the Barbieri Chart Generator and select the reference file from the CLReferencesBarbieri folder.
Add the desired options to the chart, e.g. auto positioning markings, reference area, etc., and Save the target file.
Load the reference file into ColorAnt by dragging and dropping the .ref file onto the Data Sets window. The target file can be found in the Gateway>Targets folder.
If the patches do not match the printed chart, right-click on the reference in the Data Sets window and select Swap Rows with Columns. Check the patch arrangement again in the View tool.
Select the reference file and click Measure. Ensure that the correct chart has been selected. Select the Spectro LFP qb from the device list and click Connect.
Once the device is connected, the Spectro LFP qb wizard will be displayed. Simply select auto positioning and click Start.
