PRINTING INKS

PRINTING INKS

Printing Ink Driers typically consist of only oxidative driers since the very thin ink films do not require through driers. However, there are a number of other metal based and non-metal based additives that can be used to further optimize the drier package. DURA offers a number of standard liquid driers and additives for printing inks.
