Whether it is sheet-fed or web-fed printing, if flat die-cutting is provided, there are some defects in the subsequent processing. Therefore, the choice of die-cutting process becomes the second most important factor in carton processing.
Although the price of round die-cutting die is higher than that of flat die-cutting die-cutting die, the gradual reduction in the price of round-bore die-cutting die and the gradual improvement in its reliability have made the scope of popularity ever expanding. At present, more and more carton processors have realized the superiority of circular press die cutting, which is mainly reflected in higher processing speed, similar consistency of processing technology, lower investment, and simple and rapid preparation process.
Modern round die-cutting dieboards have been manufactured with great precision. Most of the prepress preparation work is done in the die shop. Die-cutting plates, blanking, and indentation pads are prepared for printing. Businesses have ceased to exist, printing companies only need a thin double-sided adhesive version is sufficient, reducing costs.
Of course, the most important of all the factors is still the production efficiency. Compared with the flat die-cutting die-cutting process, the production efficiency of the round die-cutting die-cutting process is much higher. After successfully adopting such methods as reducing blanking blanks, the success factor of carton processing production lies in the amount of processing per unit time, ie, how to increase production efficiency. Although the combination of flat die-cutting and web printing process also has a high processing speed, the high equipment maintenance costs, difficulties in die-cutting and discharge, and the difficulty of registration make the actual processing productivity inferior Round pressure die cutting process.
Circular die cutting is not a panacea, and the large-format printing of small carton production processes using flat die-cutting die-cutting process still has advantages, and in some respects even exceeds the processing capacity of narrow-width turn + round-press die-cutting process. However, it should be noted that there are many types of round-press die cutting machines that require considerable knowledge to make successful choices.
