1. Introduction to Inline Flexo Printing

Inline flexo printing refers to a configuration where printing units are aligned in a straight line. This setup enables continuous operations, combining several stages of production into one seamless workflow. It is ideal for industries requiring high-speed and high-volume production.
 

2. How Inline Flexo Printing Works

Inline flexo printing uses flexible photopolymer plates mounted on rotating cylinders to transfer ink onto the substrate. The process typically includes:

  • Material feeding
  • Ink application using anilox rollers
  • High-precision plate printing
  • Drying and curing
  • Optional processes like laminating and die-cutting

Machines can print 1-9 colors and achieve speeds up to 150m/min with ±0.1mm registering precision.
