1. Plastic gravure composite carton technology Using single-sided corrugated board production line, if still need to cover the light glossy paper printing after the completion of the membrane, and the production batch is bigger, can not on the surface of paper printing, and intaglio printing way on plastic film gravure printing, and combined with white, then printed plastic film and the surface paper composite first, then according to the regular carton box molding process to complete the system. The characteristics of this process are: low production cost of cartons when the production batch is large, this process can greatly reduce the printing cost of surface paper and the material cost of surface paper. Because the face paper does not need to be printed, so you can use non-coated white board, so that the cost of face paper is greatly reduced. Beautifully printed. Because of the use of plastic gravure printing, so the printing effect can be comparable to offset printing. Special attention should be paid to the use of the process, in the plate printing, to fully consider the plastic film size changes and deformation; Otherwise, the carton surface paper will not be aligned with the lower layer of cardboard. 2. Copperplate paper gravure printing composite carton process when the production batch is large, do not need to laminate, and the printing effect is good, low cost, you can use this process. The process is to first use paper gravure printing machine to print thinner coated paper, and then compound the beautifully printed coated paper with ordinary slag board or carton board, as the whole paper, and then mount and normal carton forming processing. This process is characterized by low production cost of cartons. The main reason for the cost reduction is that the white board is changed to low weight coated paper and cheap box board compound, reducing the cost of materials. Beautifully printed. The printing effect of paper gravure is very exquisite. Gravure plate making is more complex, and the cost is high, not suitable for printing often modified carton products. The operation and control methods of the process of paper compound and box making in the printing factory should be explored carefully, accumulated constantly and implemented reasonably, otherwise it is easy to lead to an increase in the rejection rate. 3. Direct offset printing corrugated carton process corrugated carton direct offset printing process has been relatively mature in foreign countries, it is the corrugated cardboard directly printed on a special offset press. Suitable for processing thin corrugated boxes. The process can not only ensure the cartons good formability, and can accomplish fine surface of paper printing, but the printer price is quite expensive, and the demand of our country standard is less, is not suitable for carton industry in the near term used, but in the next few years, the process may be as a new development direction of high-grade cardboard box printing in China. 4 flexo printing and gravure printing corrugated carton process in recent years to develop relatively fast, these two processes are the first to web printing surface paper, and then complete the production of corrugated board in the automatic corrugated board production line. Carton printing quality and molding quality are relatively high, but the investment is relatively large, also not suitable for small batch production. In the domestic carton industry, the three conventional corrugated carton printing methods are widely used, and have become the mainstream of corrugated carton printing at present. And the new printing box making mode, because the equipment, materials, process, operation and other technical hot spot has not been fully mastered, the investment is also relatively large, the difficulty of promotion is still relatively large. But in order to improve the grade of carton enterprises, reduce the total cost of carton, obtain the maximum profit, increase the competitive advantage in the market, the use of new printing process is imperative.
