Establishing the image geometry reference values
To establish the image geometry reference values, proceed as follows:
1. Print the QC test image or use the previously printed test image.
2. To determine the reference values for geometry, measure the distances A
and B of the geometric square on the test image.
3. Record these values as reference dimensions A
('Geometric Consistency Control Chart').
These charts will be used for the annual quality test.
4. Save this film for future reference.

WARNING:
Make sure to measure distance A from the left edge of the
left line to the right edge of the right line and distance B
from the upper edge of the upper line to the lower edge of
the lower line.
We strongly recommend using a 30 cm (12-inch) machinist
scale with 0.5 mm divisions (1/64 inch).
