Ink drying speed: how to measure pH & conductivity?
First, thanks to the owners/moderators of this forum for starting this category. It's very handy to have a dedicated "ink" topic placed here.
My question: for those pressmen out there who measure your own fountain solution pH and conductivity, what kind of device do you use to measure it?
