"India ink" or "Encre de Chine" have nothing to do with the following mediums, that should be called only permanent, waterproof, covering or indelible inks. Their pigments are mixed with acryl so that the liquid can dry on the surface of paper as quickly as possible. That's the most popular ink for advanced calligraphy (Western Hebraic, Arabic) as well as drawing, mapping and manga-ing.The best products are American (the six first lines) or German.
