1. Introduction Kansai Enkō 45 (関西 エンコー 45) is a line of high‑quality, water‑based drawing inks produced by the Kansai Ink Co., Ltd., a well‑established Japanese manufacturer that has been supplying artists, designers, and calligraphers since the early 20th century. The “45” in the name refers to the product’s viscosity class (45 cP at 25 °C) and also to the original year of launch in the Japanese imperial calendar (Shōwa 45, i.e., 1970). Over the past five decades the ink has become a cult favourite among illustrators who demand a balance of flow, saturation, and archival stability. 2.
