Ink Formula Guide

Colorant Key

We've compartmentalized our ink recipes into four principal categories characterized by differentiating elements of the colorant component in the formula. A colorant is a dye or pigment that exhibits color. An ink vehicle is a series of chemicals used to transport colorant from storage reservoir to substrate (paper in our case). 

Keystone Formula

Keystone Formula inks are engineered using water-soluble dyes to produce a broad spectrum of colors with a variety of unique and desirable writing properties. Fitting the bill for a traditional fountain pen ink, this series by far the most popular. 

Delicate Formula

Delicate Formula inks are constructed with dyes selected for both performance and washability. Colors in this series will clean easily from most fabrics and surfaces with soap and water.

Everlasting Formula

Everlasting Formula inks are compounded with pigmented colorants to produce highly water resistant and archival properties on paper.

Twinkle Formula

Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.
