An Indian manufacturer of self-adhesive labels has installed automated label inspection systems to improve quality control in its production process.

Webtech Industries has invested in three Prati Sun TE330 slitter inspection rewinders, equipped with camera systems from Allied Vision Technologies (AVT), to help it continue its rapid growth in the pharmaceutical and healthcare sectors and aid its expansion plans into the cosmetics and FMCG markets.

'We evaluated many systems for our slitting/rewinding and inspection requirements and found the Prati machines ideal for our needs and expectations. The simplicity in design, sturdy build quality and easy compatibility with 100 per cent defect detection camera systems were the main features for us,' commented Amar Chhajed, who founded Webtech in 1998.

The inspection rewinder detects missing labels, colour discrepancies as well as a matrix waste on a wide range of pressure sensitive labels, unsupported paper, cardboard, as well as aluminium. If equipped with inkjet print-head, it is able to overprint not only variable data such as barcodes and product codes, but also special inks. The servo technology applied on the machine allows the integration with all camera inspection system brands. The system can process web widths up to 330mm and is a great cost-saving investment combining mechanical precision with electronic technology.

Chhajed commented: 'We hope to improve the quality standards of the label industry in India taking them to international levels and even exceeding them in many cases.'
