Something Special

They've come a long way since the days when conductive inks were only screen printed. Battersby said, "Polymer thick film (PTF) inks, which have been available for screen printing for decades, were the first example of a dispersion of conductive metal particles in a polymer vehicle. Much work is being done these days to adapt this type of material (and other, newer materials) to higher-speed print processes like flexo and gravure."
