# Printing the Calibration Pattern Using the Print Grid Dialog

Note:

- Use the Print Grid functionality only in situations of coarse measurements and experimentation, and not in applications that require a high degree of precision and accuracy (a precisely fabricated calibration pattern is required for those types of applications).
- You must select an In-Sight 2800 or In-Sight 3800 in the device list in order for the Calibration Grid button to appear.

1. Open the In-Sight Vision Suite.

2. Click the Print Calibration Grid button.

3. Set the values for the grid.

   - Grid Type: you can choose between two types of checkerboards.

     - Checkerboard, with fiducial
     - Checkerboard, no fiducial
   - Grid Spacing: you can choose the size of the grid. The default value is 10.
   - Grid Units: you can choose the measurement unit for the grid. The default is milimeters.

4. Click the Print button.

5. Place the printed grid before the camera.
