BAR WIDTHS BEGIN TO
COMPRESS
Below is a scanned image of a typical application where there was an
acceleration and deceleration component in the line movement. Notice how the
bars grew from left to right then began to compress towards the normal at the
right. Also apparent is the change in the optical density of the pattern. This was a
totally unreadable code.
Finally, the image as it should look. This code was produced on white corrugated
at 100ft/min and produced a verifiable class “A” with a decodability of 70%. The
average bar growth from the reference standard was 0.03%.
