What is "archival ink"?
I'd agree if the ink used is "india ink" (carbon black based ink --
the classic stuff used in Chinese/Japanese calligraphy). At one
point, pen plotters could accept drafting pens, such as the famous
Rotring/Rapidograph. Fill one with india ink and plot on vellum, keep
it try, and you should be ok for many centuries.
Any other kind of ink I'd wonder about.
