In order to verify label flatness and integrity, a dark field illuminator should be used to highlight curling or wrinkles. These areas will appear as shadowed or dark in a machine vision image. Acceptable parameters can be based on process control methods utilizing thresholds set for maximum number of pixels.
In addition, a machine vision system can inspect for proper label positioning, proper label content, and color.
