The invention discloses a carton paperboard material saving die cutting method. The method comprises the following steps of overall planning, unit printing area planning, unit printing area printing,paperboard machining, printing, die cutting position planning, die cutting and fine machining. As a first pattern and a second pattern in a carton paperboard machined primarily are of center symmetry,matching of a long bottom face and a short bottom face between the first pattern and the second pattern can be achieved, the first pattern and the second pattern are close as much as possible, thus,when fine machining is carried out on the carton paperboard machined primarily, materials needing to be cut off can be reduced as much as possible, the utilization rate of raw materials is increased greatly, waste is reduced, and the manufacturing cost is reduced. Accordingly, the printing position and the die cutting position are arranged to be different positions, it can be ensured that printingand die cutting machining can be carried out accurately, moreover, the machining cost can be reduced, the machining raw materials can be saved, and the machining practicality is improved greatly.
