The present invention addresses the problem of making it possible to highly accurately calibrate a printing position and highly accurately printing characters and the like on a solid preparation (e.g. a tablet). This solid preparation printing method is designed to print characters and the like on a solid preparation T and characterized by comprising: a mark printing step of printing a mark CM for calibration of a printing position of characters and the like on the solid preparation T, which is an object on which the mark is to be printed； and a character printing step of printing characters and the like PM which are different from the mark CM on the solid preparation T, which is an object on which the characters and the like are to be printed.本發明提供一種將文字等印刷於於固形製劑T上之固形製劑印刷方法，其特徵在於，具有標記印刷步驟與文字等印刷步驟；其中，該標記印刷步驟是指，將用來校正文字等的印刷位置之標記CM，印刷於作為標記印刷對象的固形製劑T上；該文字等印刷步驟是指，將與該標記CM相異的文字等PM，印刷於作為文字等印刷對象的固形製劑T上。本發明使得印刷位置的校正能高精準地進行，並將文字等高精準地印刷於錠劑等固形製劑上。
