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
