Jīn Jiǎn 金簡 (?–1794), courtesy name Kětíng 可亭, posthumously Qínkè 勤恪, was a high-Qiánlóng Manchu bannerman official of the Bordered Yellow Banner (xiānghuángqí 鑲黃旗) and the principal director of the Wǔyīng diàn 武英殿 imperial palace printing office in the era of the Sìkù quánshū 四庫全書 commission. He came of a Korean-descended Manchu family — sister of his mother’s lineage was Lady Jiā 嘉氏, a consort of the Qiánlóng emperor; his father had served as Nèiwǔfǔ zǒngguǎn 內務府總管 (Director of the Imperial Household Department), and Jīn Jiǎn rose through that department to Hùbù shìláng 戶部侍郎 (Vice-Minister of Revenue), with concurrent responsibility for Sìkù publishing.
His central contribution is the establishment of the Jùzhēnbǎn 聚珍版 (“Assembled Treasures Edition”) wooden movable-type system, proposed in his memorial of Qiánlóng 38 (1773) as a labour-saving alternative to woodblock cutting for the Sìkù-publishing programme; over 134 titles in the Wǔyīngdiàn jùzhēnbǎn cóngshū 武英殿聚珍版叢書 were printed by this system from 1774 onwards. He documented the system in KR2m0057 Qīndìng Wǔyīngdiàn jùzhēnbǎn chéngshì 欽定武英殿聚珍版程式 (1776), the most detailed pre-modern East Asian technical manual for letterpress printing.
CBDB id 57085 records death in Qiánlóng 59 (1794), following Qīngdài rénwù shēngzúnián biǎo, with index year 1731. The catalog meta gives “d. 1795”, reflecting the lunar–Gregorian boundary; the Hummel-tradition Western reference uses 1794. He was also the leading Manchu compiler of the Manchu-Mongolian-Chinese imperial dictionaries of his period.
