Solvent emission - VOC Control in flexographic printing

Volatile Organic Compound (VOC)

In most situations solvent-based inks used in flexographic printing still provide a better alternative over water-based and UV inks. However, they contain Volatile Organic Compound (VOC) in varying amounts, depending on the type of ink, the drying and printing processes, substrates and end-use application requirements.

VOC is any organic compound which, when released into the atmosphere, participates in the atmospheric photochemical reactions. Ground-level ozone is produced when nitrogen oxidises and volatile organic compounds (VOC's) react in the presence of sunlight. This is a major component of urban smog, which, at elevated levels, presents a potential health hazard to people, damages vegetation and degrades the environment.

It is for this reason that government legislation to control solvent emissions is being implemented in the Europe, US, Canada and other parts of the world (see VOC solvent directive).


There are several ways to meet the VOC Directive. RTO and recovery are examples of possible solutions. We believe the most cost-efficient system is the VOCUS. More important, the VOCUS system operates without emitting CO2. And CO2 is another very harmful substance for the environment.
