Different kinds of paper printing process

Carton products commonly used printing process, mainly offset printing, convex printing(soft printing) and Gravure printing three processes. Each of these three forms of printing has its own advantages. Therefore, it is necessary to weigh the advantages and disadvantages according to the actual conditions of the factory and the characteristics of the products, and to choose the appropriate process for printing production, in order to better reduce the cost of printing production. Improve printing production efficiency and quality of products.



1, Offset printing process
The offset printing process has multi-color groups, multifunctional reel paper and flatboard paper models. The former has a high production speed and can be suitable for pre-printing cartons with large production volumes and a relatively fixed product structure. After the surface paper is printed, It can be directly bonded with corrugated cardboard on the corrugated production line. The printing speed of the latter can reach about 10,000 sheets per hour, which is suitable for printing medium-and small-volume carton products. The printing specifications of surface paper can be flexible and changeable.

2, Gravure printing process
The Gravure printing process also has the distinction between a reel paper and a tablet paper printing press. The color group and function also have a variety of models. The printing process has the characteristics of higher printing resistance and faster printing speed.
Due to the thicker ink layer, full and three-dimensional printing ink color, rich layout printing layer, strong texture, printing ink drying speed is faster, so it is more suitable for large areas, thick ink printing products. The Gravure printing process can be suitable for printing field and special color line plates, and can also print fine mesh plates. Compared with the processes such as offset printing, soft printing or silk printing, the process is the least likely to produce printing color difference. The printing quality of cartons is the most stable and the best. Since the Gravure plate material is made of steel roll materials processed by electroplating, electric carving and other processing processes, the plate preparation process is relatively complex, the plate preparation materials and costs are also relatively expensive, and the replacement operation is also more troublesome, so, It is especially suitable for the large number of pre-printed carton printing production, in order to better reduce the production cost.

3, Flexible printing process
The flexible printing process also has a multi-color printing press with reel paper and flat paper. Among them, the flat paper printing press has a pre-printing model for printed surface paper, as well as direct printing of corrugated cardboard, and can be completed online. Cut, indentation, slot unit. Flexible printing technology is compatible with the advantages of relief, lithography, and Gravure printing. Since the printing plate is flexible, the printing pressure is much lighter than other processes, it has lighter printing pressure, thick printing ink, and clear printing. Main characteristics of high printing resistance of printing plate.
