Hollowing of Dots
Try the following countermeasures when dots appear “hollowed,” i.e.,
the centers of dot images are white.
Countermeasures
• The influence of hollowing can be decreased by increasing the
field of vision and thereby decreasing the size of the code image.
• The influence of hollowing can be decreased using the smooth-
ing function (0. Image Adjust/Filtering).
• The influence of hollowing can be decreased by adjusting the
BGS levels (0. Image Adjust/BGS Levels).
