Pigma Micron®: Proven Permanence

Pigma® ink, invented by Sakura over 25 years ago, continues to be the most reliable permanent ink on the market today. Laboratory notebooks and log books offer a complete and tamper resistant means of documenting work. Pigma ink easily outlasts and out-performs competitors, and is the preferred choice for scientists, curators, courts, and others who value quality ink and preservation.


What Makes Pigma® Ink Different?

Sakura invented pigment ink as an alternative to the unstable dye based inks available at the time. The Pigma Micron pen uses superior pigment based inks that are more chemically complex and 100 times bigger than dye molecules. This makes pigment ink less susceptible to UV rays, chemical degradation, and pollution from contact with oils and other chemicals. However, pigments by themselves do not guarantee that an ink is permanent. Sakura further developed Pigma ink and Pigma Micron pens to be fade-resistant, waterproof, chemical resistant, lightfast and non-abrasive on most writing surfaces.If you need your critical notes and intellectual property to withstand time, the elements, or difficult lab conditions, use Micron pens to preserve your work.

Pigma Ink and Your Archival Notebook

Pigma Micron pens also protect the pages of lab notebooks and log books because Pigma ink molecules only penetrate the very top layer of the writing surface.

  • Prevents bleed through and enables writing on both sides of the paper.

  • Dries to a neutral pH, neither acidic nor alkaline, protecting the pages of your archival notebook.

  • Feature durable nibs that will not damage the surface of the paper.

What Museum Professionals are Saying About Pigma Microns

“Pigma Micron is the ideal pen to use for archival purposes. When archival and museum professionals reach to mark an invaluable object in their possession, we want to be sure that the ink does not smear or bleed. Pigma ink is waterproof, chemical-proof, fade-resistant and nontoxic, thereby making them ideal for my museum tool kit. The pigment-based ink is chemically stable and will not harm the object, document or specimen. Microns are the go-to marking instrument for all the collections in my care.”
– Lindsay Palaima, Museum Registrar

“Using keen observational skills to accurately render a natural subject represents one of the basics of scientific illustration. All sizes of Pigma Microns, especially .005, allows me communicate the appropriate message and render light on form naturally, via stipples or the most delicate of lines. The archival ink and diversity of values never fail to translate the scientific concept to a broader audience.”
