I recently started a new job on a flexo press and I just need someone to explain to me how to determine what the goal PH and viscosity of the ink. I’ve been on the press for a few days and I have a small understanding of that. The rest I’m picking up quick and I know how important it is and would like to understand it better. Thanks in advance.

The pH is determined by the ink mfg.
It will change the viscosity of a water based ink, not solvent or UV ink.
pH is a logarithmic (log) scale so small changes in the value are big differences (factor of 10x).
