Curious to see how ink goes in a simulation, i've posted my results before from real world prints, but here's some simulations for you.
3.2mm wide trace, 40mm long, of V1 ink (0.012ohm/sq, 0.1mm thick) on 1.6mm FR4 with a lossless ground plane.
This is better than my real world testing came up with... but whatever, it gives us a relative point to work from. If this was copper, it would be an almost 50ohm trace - I'm using 3.2mm because thats the closest a V1 can print with it's 0.4mm printing width.
As a comparison, a 0.4mm wide, 40mm long ink track, on the same 1.6mm FR4:
Even a 1.2mm wide ink track is far superior:
I don't have any single clad FR4 that is 1.6mm (1/16") thick around, or I'd print you some tracks to show you real world results
