Water-based ink printing corrugated paper four ways

Water-based ink printing corrugated paper four ways

The corrugated carton industry use water-based ink printing equipment has four kinds of production methods, their features are different.
  1. Chain type single printing way, this way can only printing, slotting and die cutting.
  2. Commonly used printing slot and circle pressure circle die cutting production mode, this way to use up the ink printing, the slot or after die cutting, forming in a glue nail (box).
  3. Using automatic printing and slotting, fold glue nail (box) production mode, the machine used for folding forming on ink printing system, is a one-time molding machine.
  4. At present more advanced way of printing, die cutting circle, its characteristic is multicolor printing, high precision equipment, printing products can reach the effect of color printing, especially suitable for the sales of color box packaging. The above several kinds of production methods, their common characteristics are using ink printing, the printing principle and equipment structure is basically the same, just how much color, net line number and process equipment. Printing process influenced by many aspects and factors and constraints, a lot of problems is not simple adjustment can solve by operators. Only through all aspects of the coordination, as far as possible to reduce and avoid some unnecessary problems in production process.

 In this paper, the printing ink easily or often appear, analyses the common problems and take necessary measures accordingly.

    Solution: first, when you make 1:1 ink figure should be drawn according to the normal percentage of shrinkage. Typesetting figure position adjustment in accordance with the ink print. Should be used in matching color accuracy requirement is high, "cross" layout method, on the reticle plate and ink figure, a magnifying glass to check if necessary.

   3. The problem of printing white ghosting and the drain
   Cause analysis: both of these issues is often appear in the process of production. A ghosting around the printing logo or because the anilox roller and plate caused by stress; Print in the front edge of ghosting, because between the printing roller and embossing roller pressure is too large. Large area of printing a trainspotter, leakage white is due to the printing roller and embossing roller pressure generated enough. The two problems are caused by the opposite pressure.
