Vision Inspection Systems Drive Profits

Faster cameras are available to enable the latest generation of gravure and flexo presses to perform without quality compromise at higher speeds. Recommended inspection camera resolutions are 250 dpi, although a maximum of 2,500 dpi is possible; cameras must be able to detect defects from

Cross-substrate resolution is critical. The printing process is a dynamic process. For instance, an ink splash, spherical as it approaches the substrate, becomes a long, oval stain due to the substrate's relative velocity. In gravure, doctor blade defects are serious, potentially running for hundreds of feet, but may be just 0.1 mm wide. The narrowest field of view (FOV) per camera is 180 mm, although optics to allow for narrower FOVs are possible. There is no limit on the maximum width.
