Hard gelatin capsules

Thousands of different capsules are produced every day, so it is inevitable that some of them will come out defect in shape or size, with a colour deviation, cracks, dents or maybe a missing print. However, a defective capsule in a package can lead to unpleasant consequences. A complaint or even loss of brand are the worst-case scenario for a manufacturer.  Reliable detection of defects depends on quality of inspection system, where 3 key aspects have to be considered: optical system, mechanical manipulation and image analysis.
