The printing press printed wide-web the semi-finished product. Subsequently, the printed semifinished product fed to a punching device, in which of the semi-finished single printed sheets are punched out. After punching out will be the sheets stacked and by means of suitable cars to a finishing machine promoted. At the finishing machine, the Cardboard individually picked up, then glued, folded and then processed into a carton.
  • a Quality control must be subjected to a sufficient To ensure quality standard of manufactured cartons.
  • Quality control is usually done in such a way that, for example a batch of 1,000 sheets about 50 sheets are taken, which then Manually controlled by a quality inspector. Being at the control a critical error rate is determined, it is usually provided to destroy the entire batch. It is understood that such a Control mode is relatively expensive because on the one hand a test person manually review a large number of sheets of a batch. On the other hand This method of control is uneconomical, since when reaching a critical Error rate the entire batch is destroyed. In practice means This is often the case, that sometimes 90% of the printed sheets for the other Production can not be recycled. It is understood that one such a high rate of wastes at the expense of competitiveness.
