Standard Test Method for Determination of Open Time of Oxidative Printing Inks and Overprint Varnishes by a Manual Method

Importancia y uso:

3.1 When formulating printing inks and overprint varnishes that dry primarily by oxidation it is important to know the stay open time so that premature drying does not occur on the printing press rollers and other components.

3.2 The applied ink or OPV film used for testing is thicker than the film printed on the substrate and nominally represents the film on the printing press rollers.
