Buying Guide: Waterproof Black Fountain Pen Inks
What should you consider before choosing waterproof black ink?
- Ink type: Pigment vs. dye vs. carbon-based inks each behave differently on paper. Pigment inks tend to be more water-resistant and fade-resistant but can be thicker. Carbon and dye-based inks may offer smoother writing but different permanence levels on certain papers.
- Paper compatibility: Some inks feather or take longer to dry on coated or glossy stock. Test on your common paper to ensure legibility and drying time meet your needs.
- Nib compatibility: Some inks flow more generously and may require nib tuning or a suitable nib size to prevent ink flooding or skipping.
- Drying time and permanence: For documents, you’ll want quicker drying and robust permanence. For artwork, balance line precision with tissue resistance.
- Archival standards: If preserving documents long-term is a priority, look for inks described as archival or designed for permanence and resistance to water and fading.
