Here's two different conductive inks. The black bare conductive ink has better printing properties - it can pass easily through a 130 mesh screen and won't dry up. However, it's resistivity is higher than the copper paint on the left. The copper paint, from less EMF, is problematic for basic screen printing. It passes only with difficulty through a 130 mesh screen, separates very quickly, and dries up fast. Due to the high resistivity, only the parallel structure (on the left) can make a reasonably convincing signal.
