Pigment ink pens are primarily used for applications requiring permanence, water resistance, and fade resistance. Pigment inks are insoluble in solvents and offer excellent dispersion in the ink.
Here's a breakdown of their key uses:
-
Archival Documents and Artwork: Because of their lightfastness and chemical stability, pigment inks are ideal for creating documents and artwork intended to last for a long time. This makes them a popular choice for artists, archivists, and anyone needing to preserve important creations or records.
-
Technical Drawing and Illustration: The water resistance of pigment ink makes it suitable for technical drawings and illustrations where the lines need to remain sharp and clear, even if exposed to moisture. This is especially important when layering inks or using washes over the drawing.
-
Calligraphy: Pigment inks are frequently used in calligraphy due to their smooth flow, consistent color, and archival qualities.
-
Legal Documents: The permanence and tamper-resistance of pigment ink make it a suitable choice for legal documents that require a high degree of security and longevity.
-
Permanent Labeling: Pigment ink pens can be used for permanent labeling on a variety of surfaces because of their water-resistant and fade-resistant qualities.
-
Dyeing: As mentioned in the reference, pigment inks can be used as dyes to give the ink sufficient color depth. However, this is more a component of ink formulation than a distinct use case for using a pigment ink pen. The primary use of a pigment in the pen context is to create lasting marks.
Pigment ink pens excel in applications where permanence, water resistance, and fade resistance are crucial, making them a valuable tool for a range of artistic, professional, and archival purposes.
