Measuring And Marking Out
Akopọ
Before a single cut is made in card or board, the work has to be measured and marked out, and the accuracy of everything that follows depends on getting this stage right. A carton that is creased a millimetre off will not fold square; a logo placed by eye will sit crooked on the panel. In graphic products, measuring and marking out is the quiet discipline that separates a crisp, professional result from an amateur one.
This note covers measuring and marking out for paper, card and board using the right hand tools and equipment, and increasingly using CAD tools as well. It explains how to read a steel rule accurately, how to set out square and parallel lines with set squares and a try square, how to mark and check angles, how to lay out repeated and symmetrical features, and how the same marking-out logic is carried out digitally before sending a job to a cutter or plotter.
