Comparison of Common Printing Methods of Several Corrugated Boxes

1、 The processing technology of corrugated board the processing technology of corrugated board is mainly divided into two categories

       Production process of full-automatic corrugated board production line this corrugated board production process is widely used and has the advantages of large production batch, large carton forming volume, good corrugated shape quality and so on. Comparison of Common Printing Methods of Several Corrugated Boxes

       The corrugated board produced by this process is usually made into cartons through water-based printing, slotting, pasting, molding and other processes. The cartons produced by this process are mainly used for transportation packaging.Comparison of Common Printing Methods of Several Corrugated Boxes

       Production process of semi-automatic corrugated board production line. The corrugated board production process is to first print face paper, and then mount it with corrugated core paper and paperboard. Comparison of Common Printing Methods of Several Corrugated Boxes

      The corrugated board produced by this process is usually packed into boxes by die-cutting, indentation, nail sticking and other processes. The carton produced by this process has good forming quality and surface treatment effect. The cartons produced by this process can be used as sales packaging.Comparison of Common Printing Methods of Several Corrugated Boxes

      Conventional carton printing methods conventional carton printing methods mainly include flexo printing, offset printing and screen printing

        Flexographic printing corrugated box the conventional flexographic printing corrugated box process is to print directly on the corrugated board, using water-based ink. Therefore, some people also call this process watermark. Flexographic direct printing has the following characteristics:Comparison of Common Printing Methods of Several Corrugated Boxes

(1) Large format. The maximum width of a wide flexographic press can reach 2.5m-2.8m.

(2) The price is low. Flexo has high printing resistance and can be reused; the price of ink is also low.Comparison of Common Printing Methods of Several Corrugated Boxes

(3) Can linkage production, such as printing, slotting, indentation, ordering (gluing) boxes, baling and so on.

(4) Because flexo printing is light pressure printing, it has little effect on the strength of corrugated board.Comparison of Common Printing Methods of Several Corrugated Boxes

(5) The printing accuracy is not high. The number of conventional offset screen lines is 175 lines / inch, while the number of conventional screen lines of flexographic cartons is 35 lines / inch – 65 lines / inch. It is a low-precision printing method, which is most suitable for printing text line manuscripts. Although the printing quality of four-color images has been improved in recent years, it is still limited.Comparison of Common Printing Methods of Several Corrugated Boxes

(6) Plate making is easy and difficult, text line draft plate making is easy, and four-color image plate making is more difficult.Comparison of Common Printing Methods of Several Corrugated Boxes

(7) The stability of printing quality is not good, which is mainly reflected in the difficulty in controlling the depth of printing ink. Flexographic direct printing process is suitable for the production process of class I carton. At present, it is widely used in carton factories in China.Comparison of Common Printing Methods of Several Corrugated Boxes
