actual printing; main printing
Printing term for the final production run, as opposed to a test print or proof. Used in contexts like publishing and commercial printing.
Proofreading is finished, so we'll start the actual printing tomorrow.
Please check the color proof carefully before the main printing.
Compound of 本 (ほん, 'main; real') and 刷り (ずり, 'printing', the continuative form of 刷る). The reading ずり is a rendaku form of すり.
