I do work with a a few plotters, both pre petis buyout EMS plotter, a vintage HP, and a custom built plotter.

Everything he says here is true, but to me at the end of the day after running some of my work off on very high end inkjets and dyesubs. It's just not the same. There is an inherent, and i'm not sure how to fully communicate this, physicality to a plotted artwork. Slight imperfections in ink flow, the way fountain ink behaves when lines cross, the way the ink bleeds into the medium you are plotting on, the inks (or other mediums) you can choose vs what you can put through an inkjet. It's like comparing an oil painting to even a high quality print of that oil painting. You lose texture going to inkjet.
