再版 (zài bǎn) literally means 'again + edition' and refers to the process of printing or issuing a book, article, or other published material for a second or subsequent time. The character 再 means 'again' or 'once more', while 版 originally meant 'printing plate' and now broadly denotes 'edition' or 'version'. Together, they form a compound noun indicating that a previously published work has been reproduced—often with minor revisions, corrections, or updated content, though sometimes unchanged.

This term is used primarily in publishing, academic, and literary contexts. It’s common in discussions about books, journals, textbooks, and even digital publications. Unlike informal terms like 重印 (chóng yìn), which emphasizes physical reprinting, 再版 often implies official reissuing—sometimes with a new ISBN, cover, or editorial note. It carries a neutral-to-formal register and is rarely used for non-published items like songs or films (where 重映 or 重播 would apply instead).
