What it is

A bronze type font cast in 1434 by order of King Sejong, with more regular sorts and a forme that holds them with bamboo wedges instead of wax. According to the chronicles it doubled the number of pages printed per day.

Earlier fonts (Gyemi, 1403; Gyeongja, 1420) fixed the type with beeswax; Gabinja fixes it with bamboo wedges. The doubling figure comes from the Sejong Sillok.

What it led to

  • official printing of agronomy, medicine, history and classics in metal type
  • technical refinement of Korean type founding (Gyeongja and Gabin fonts)
  • printing infrastructure for Sejong's cultural policy
