Registration drift
Small lateral errors can create colour-to-colour registration issues and downstream trimming waste.
Printing & Label Converting
Web Guiding and Tension Control for Printing Lines
Printing quality depends on steady web tracking, controlled tension and repeatable registration through unwind, print, inspection and rewind sections.
Control Challenges
Where print quality is lost
Unstable unwind tension
Changing roll diameter can affect web tension and print repeatability if the unwind zone is not controlled.
Sensor target variation
Printed marks, contrast changes, transparent films and paper edges may require different sensor choices.
