Automatic Web Offset Printing Press
Description
SMART-420 web offset printing press is the first horizontal rotary machine from ZONTEN company. Many customers will ask, why not do a full-rotary flexo printing machine, but instead do a more difficult rotary web offset printing press?
As an equipment manufacturer with 12 years of offset printing experience, we are deeply aware of the prominence of offset printing process in printing quality, which is unmatched by flexographic printing machines. Now that the printing process is increasingly demanding, the dot reduction rate and printing quality exhibited by offset CMYK 4 primary color overprint printing are what customers expect. Therefore, the combined process CMYK4 primary color offset printing + spot color flexo printing provided by SMART-420 satisfies customers' wireless imagination.
In addition, the web offset printing press has low ink usage, mature plate-making technology, and low plate costs, allowing customers to save a lot of money in auxiliary materials.
