Paper & Print
Industry overview
On paper and print lines the material runs roll to roll without interruption; holes and tears, colour-to-colour register, colour tone and print defects are monitored while the line runs. Line-scan cameras tie the image to the encoder, so every finding is logged with its metre position on the roll.
