Offset printing process
The offset printing process has a multi-color group, a multi-function web and a flat paper machine. The former has a high production speed and can be suitable for printing pre-printed cartons with large production batches and relatively fixed product structure. After printing, the corrugated paper can be corrugated. The corrugated board on the production line is directly bonded and bonded. The printing speed of the latter can reach about 10,000 sheets per hour, which is suitable for the printing of medium and small batches of carton products. The printing specifications of the facial paper can be flexible. The flat paper machine can also directly print fine corrugated cardboard, and its overprinting precision is higher than the former, and the quality is relatively stable. Offset printing ink layer is more suitable for overprinting or overprinting of fine line and multi-color screen printing. It has high dot resolution, rich printing layer, clear boundary, soft color, good printing and reproduction. The printing is convenient and fast, the printing plate is easy to operate, the printing operation is easy, and the printing cost is low. It is widely used in the printing of color pre-printed carton paper.
2. Gravure printing process
The gravure printing process also has the distinction of web and flat paper printing machines. The color group and function also have various models. The printing process has the characteristics of high printing durability and fast printing speed. Because the gravure ink layer is thicker, the printing ink is full and full of three-dimensional sense, the printing surface is rich in layers and strong in texture, and the printing ink color is dried faster, so it is more suitable for printing products with large area and thick ink amount. The gravure printing process can be suitable for printing on the field, spot color line version, and printing fine mesh pattern. Compared with offset printing, flexo printing or silk screen printing, the process is the least likely to produce printing chromatic aberration, and the quality of the printed product of the carton is The most stable and optimal. Since the gravure plate material is made by processing the steel roll material through electroplating, electric carving, etc., the plate making process is complicated, the plate making material and the cost are relatively expensive, and the plate changing operation is also troublesome, so it is particularly suitable for batch production. Larger pre-printed carton printing production can better reduce production costs.
