Blister packaging requires precise verification of pill placement and visual consistency to ensure correct dosage presentation and product integrity. In pharmaceutical production, errors such as missing pills, incorrect placement, or wrong tablet color can lead to serious compliance issues and product rejection.

An RGB full spectrum color sensor enables real-time inspection of pills within blister cavities by detecting both color and presence variations. It verifies whether each cavity contains the correct pill type and confirms proper alignment based on expected color patterns. This ensures accurate blister pack assembly, reduces packaging errors, and supports consistent quality control in pharmaceutical manufacturing lines.
