Machine vision systems are used in packaging lines to ensure the quality and accuracy of printed data to comply with packaging and labeling requirements. However, in the highest-speed packaging lines that employ CIJ printing, even minor fluctuations in product movement or equipment position may result in printing errors, causing machine vision systems to miss or misinterpret printed characters. This white paper provides guidance on using machine vision tools to account for the most critical CIJ printing errors, and discusses:
► Common challenges in high-speed CIJ printing that result in
illegibility or misinterpretation of data by machine vision OCR.
► How to evaluate errors to identify the key print defects that must
be accounted for by vision in a given production environment.
► Machine vision solutions for CIJ print accuracy inspection and
tips on selecting the right vision solution for a production line.
