Influence of Jet Printing Inks on Wear

This communication reports the results of wear tests performed to determine the influence of jet printing inks on the wear of several polymer-metal pairs, which were known to be compatible with the inks. It is shown that these inks generally tend to increase wear beyond that occurring in a dry state. The principal reason for this increase was concluded to be the adverse influence that the inks have on the establishment of a beneficial transfer film on the metal surface.
