noun
marking off; laying out; scribing
Technical term used in metalworking, woodworking, and similar crafts for marking lines or layout on a workpiece before cutting or machining.
金属板に罫書きをしてから切断する。
I mark the metal plate before cutting it.
罫書き線に沿って穴をあける。
Drill holes along the scribed line.
墨付け refers specifically to marking with ink, often in woodworking, while 罫書き is a broader term for scribing or marking lines in various materials.
Compound of 罫 (ke, 'rule, line') and 書き (kaki, 'writing, drawing'). The spelling 罫描き uses 描く (egaku, 'to draw') instead of 書く, but the meaning is the same.
