Automated Print Quality Inspection for Aluminium Foil Pharma Blister Packs

Lake Image Systems and Vinsak have Installed a fully integrated & automated print quality inspection system at Aurobindo Pharma Ltd., based in Vizag, Andhra Pradesh, India. This highly flexible, combined unit is used to verify the print quality of pre-printed rolls of aluminium foil pharma blister packs, prior to the roll being slit and rewound onto two smaller reels, which are then subsequently used for blister pack production.

The inspection system utilises Lake Image’s first contact image scanner (CIS) technology implementation in India, to overcome the problem of capturing, crisp, undistorted images from highly reflective surfaces.

The integrated print quality inspection equipment consists of 2 key components:

• The VINSAK USAR 330 Slitter Rewinder Unit: This modular equipment is designed to meet the increasing demands of today’s converting, security, printing, and label industry. It consists of a pneumatic expanding unwind and rewind mandrel, variable speed, and tension control system. With a digital programmable feature HMI and an electronic web guide system & ultrasonic sensor, the system is ideal for opaque and clear substrates. With all major components driven by servo motors, the equipment runs at a speed of up to 300 meters per minute.

• Lake Image Print Quality Inspection System is fully integrated onto VINSAK Slitter Rewinder and incorporates a high resolution, linear scanner unit (DISCOVERY Maxscan) with high-intensity LED lights, to capture crisp, undistorted images at 600 dpi, even from shiny, reflective surfaces. Lake Image’s DISCOVERY Multiscan inspection software then compares every captured image against a supplied master image or PDF file, in real-time to detect print defects. If an error is detected, the close integration enables the defective piece to be precisely tracked so that it automatically stops at the inspection plate for the operator to review. The print error is also shown on one of two Multiscan monitors and the nature of the error, its location, and associated information is logged. A full inspection report is available at the end of the job run.
