Quink (a portmanteau word from 'quick' and 'ink') is a fountain pen ink developed by the Parker Pen Company.The ink was novel for using isopropyl alcohol as a solvent, which dried by absorption rather than evaporation of previous water-based inks.However the composition of the ink damaged some pen barrels and caps.lthough Quink was indeed ideal for use with the 51, Parker's other pens of this generation were just as capable of using it. The Parker 51 was only made available in 1941, ten years after Quink's development.
