This large group of seventy artists, including Choi jeom-bok, Choi nam-kil, Jung bang-won, Jung yi-seul, Kim ji-young, Park kyoung-mug and Yoon yeon-hwa has chosen to define themselves with the Korean most general name of ancient art developed from calligraphy, Sum Muk, literally "Asian ink". In spite of the heterogeneity of the subjects, of which the styles of these eight exponents are representative, the use of ink remains that essential common material, with its own specific executive practice that only those who come from calligraphy can masterfully manage.
