D.2 Printing
Continuous motion printing (Figure D-2) is used for printing on moving packaging films in
packaging equipment that has a continuous moving action each time a product is packed. Such
applications can be found in Continuous VFFS and Horizontal Form Fill Seal (HFFS) or
flow-wrap machines.
Continuous motion printing has the following features:
• The substrate (item 3, Figure D-2) moves while the printhead (item 4) is stationary.
• Speed of the substrate is monitored by an encoder.
• The ribbon and the substrate speeds are matched by the ribbon drive.
• The printhead pushes the substrate against a rotating print roller (item 2).
