UV printing ink consumption and the traditional four-color process printing is the same: UV printing ink waste less. Extensive European experience has shown that average production output should be similar to traditional methods with best practices (UV fixture configuration, ink and varnish chemistry and proper operating techniques). The overall energy cost of Shanghai UV production is similar to that of the same press equipped with infrared and hot air drying devices. The test results show that the power consumption of [...]
The growth of UV printing is driven by its property of value-added printing, which can highlight many advantages in the fields of publishing, commercial printing, packaging printing and label market applications.
