Xiqing carton printing technology, simple process, economic benefits, by the vast market carton demand, printing process is also a lot, the following introduces several common carton printing process

　　1.Offset printing process

　　Offset printing process has multi-color group, multi-functional web and flat paper models, the former production speed is higher, can be suitable for printing production batch, product structure is relatively fixed pre-printed carton, face paper printing can be with corrugated paper on the corrugated production lineThe board is mounted and bonded directly。

　　The latter printing speed of up to 10,000 pieces per hour, suitable for printing medium and small batch production of carton products, face paper printing specifications can be flexible。Flat paper models can also print fine corrugated cardboard directly, and the overprinting accuracy is higher than the former, and the quality is relatively stable。

　　Offset printing process printing ink layer is more suitable for overprinting or overprinting fine line version and multi-color screen version of the printed matter，With high dot resolution，The layout printing level is rich, the level is clear，Soft tone，Printing reproduction effect is good，Printing plate production is convenient and fast，Easy operation and low cost of plate production advantages，It is widely used in the printing of color pre-printed carton paper。

　　2.Gravure process

　　Gravure printing process also has web and flat paper printing machine, color group and function also have a variety of models, the printing process has a high plate printing rate, printing speed and other characteristics。

　　Because the gravure ink layer is thick, the printing ink color is full and three-dimensional, the layout printing layer is rich, the texture is strong, and the printing ink color is drying faster, it is more suitable for large-area and thick ink printing products。

　　Gravure printing process can be suitable for printing field, spot color line plate, but also print fine mesh plate, compared with offset, flexo or screen printing and other processes, the process is not easy to produce printing color difference, carton printing product quality is the most stable and best。

　　Because gravure plate material is steel roll material through electroplating, electric carving and other processing processes made of its plate making process is more complex, plate making materials and costs are more expensive, and the plate change operation is also more troublesome, so it is especially suitable for large batch of pre-printed carton printing production, in order to better reduce production costs。

　　3.Flexographic printing process

　　Flexographic printing process is also divided into web and flat paper multicolor printing presses, among which flat paper printing presses have pre-printing models for printing face paper, and direct printing of corrugated cardboard, and can be completed online scutching, indentation, slotting units。

　　Flexographic printing process is compatible with the advantages of letterpress, lithography and gravure printing process, because the printing plate is flexible, the printing pressure is much lighter than other processes, with the main characteristics of light printing pressure, thick printing ink, clear impression, and high printing resistance。

　　The process can print both glossy board and rough board.Not only can print non-absorbent materials, but also can print highly absorbent cardboard;It can print both thin paper and thick paper;It is suitable for printing fine mesh plate, line plate, and can be suitable for printing spot color line plate or field plate。

　　Flexographic printing material has rubber plate and resin plate, rubber plate main material is natural rubber and synthetic rubber。There are three kinds of plate making: hand engraving, laser engraving and casting plate making。

　　In the use of rubber plate, attention should be paid to its printability, such as from the ink affinity of rubber, ink transfer, coverage and reproducibility, the use of water-based ink printing, with natural rubber plate than synthetic rubber plate。
