Rotating direct printing technology based on a photopolymeric plate that carries the printing image in relief instead of offset techniques which are based on an indirect ink trasmission from a smooth aluminium plate to a rubber covered cylinder and then to paper.
According to Dupont-Cyrel the prime advantages that flexography offers versus other printing methods can be summarized as follows:
  • Flexo can be used on both absorbing and non-absorbing surfaces

  • It can print short-runs cost-effectively

  • Fast, accurate printing at speed of 300 m/min (3,000 ft/min) or more

  • Can be used with a wide variety of inks, including water-based, solvent-based and UV curable

  • Relief printing plates has very long run length capabilities, up to several million impressions

  • Flexo presses can print with variable print repeat lengths

  • Extensible, stretchable films can be printed without loss of register

  • In-line operation allows printing, die-cutting and finishing in one continuous process

  • The cost for presses and on-going operational costs are often substantially lower for flexographic presses versus offset and gravure.

  • Flexo process is ideally suited for shorter runs and because changeover and "make-ready" times are les
