Throughout the printing and packaging industry,machine vision and inspection cameras are used to spot inaccuracies, defefects and poor quality print. OCR (Optical Character Recognition) technology from ABBYY can be implemented intomachine vision systems; it extracts text fromprinted

You have standard product infoformation but there’s also individual infoformation, such as the batch number or expiry date, whichmight be unique.

Machine vision and quality assurance has immense value in the production industry and it is important to help improve
efficiency. Some systems can complete up to several thousand inspections everyminute. ABBYY works directly with system

Labels and packaging come under ‘difficult texts’. The systemneeds to decide what is important to read and what is not. Image are needed to get

LESS NEED FOR HUMAN OPER TION Weber also says that productionwill only get quicker in the future, and that human interventionwill not be required asmuch. However,r, she notes that softftware has to be programmedwith the correct data in the first place in order fofor it to operate on its own.
