Clarence Schuerer may have invented the ink for the ball point pen, but it was companies like Pylam who gave that ink its final rainbow of colors we now see on the market.  Inks in pens and markers must be developed at very specific viscosities, otherwise the pens and markers won’t work. The dyes must ad color but they must not affect the basic function of the ink. The Pylam Color Engineers understand the needs of ink makers. Hundreds of ink and pen manufacturers rely on Pylam for the wide range of colors in their inks.
