This section provides necessary information required to calibrate the Scan360™ hardware and the internal scanner software.
The following topics are covered:
- Calibration Options
- Calibrate Offset
- Calibrating the Diameter
- Calibrating the Platen
- RGB Alignment
Full calibration is required when first setting up the system, after connecting the Scan360 to a new computer or after moving the system. This includes the Calibrate Offset, Calibrate Diameter, and Calibrate Platen options.
Platen calibration is required after creating a new Microsoft® Windows® user for the system.
Note: Calibrations can only be executed by a ScanProofTM Administrator or a Global Vision Support Technician.
To display the Calibration drop-down options:
- Select Scanner Source -> Scan360.
- Select Scan Master.
- When the Scan360 window displays, click the Calibration drop-down option:
This option determines the absolute position of the CCD scanner inside the scanner housing.
- Click the Calibrate Offset button.
- The CCD scanner will move to calibrate its position inside the scanner housing.
Note: You should hear a small knocking noise when the scanner hits the back of the housing.
- A message should display when it's completed.
CALIBRATING THE DIAMETER
This option determines the amount of revolution required for the support bars to scan the cylindrical object 360°. A message should display when the Diameter Calibration has not been executed.
- Click Calibrate Diameter.
- A message should display for the 1” Calibration Tool.
- Follow the steps below:
- Once the steps are completed, a message should display for the 4” Calibration Tool.
- Follow the steps below:
- A message should display when the calibration is completed.
CALIBRATING THE PLATEN
This following option calibrates the CCD scanner.
- A message should display when the Platen Calibration has not been executed.
- Click Calibrate Platen to launch ScanGear.
- Click the Preference button.
- When the Preference window displays, click the Platen Calibration: Execute button.
• Once the calibration is complete, click OK at the bottom of the Preferences window.
• Close ScanGear by clicking the Close button.
The default value for RGB alignment should only be modified if there is a clear misalignment of the Red, Green, and Blue colors. The example below shows an image where the RGB is misaligned and after RGB alignment has been corrected.
