重型包装纸箱是与我们的生活、生产密不可分的一种普通纸包装产品，重型包装纸箱的印刷质量不仅关系到重型包装纸箱的外观质量，同时也影响到所包装产品的销售前景以及商品生产企业的形象。因此，对于如何提高重型包装纸箱的表面印刷效果、如何选择好合适的印刷工艺、进一步降纸箱加工成本等问题的分析就显得尤为重要。在此我们将对这几方面加以讨论。
Heavy packaging carton is an ordinary paper packaging product closely related to our life and production. The printing quality of heavy packaging carton is not only related to the appearance quality of heavy packaging carton, but also affects the sales prospect of packaged products and the image of commodity production enterprises. Therefore, it is particularly important to analyze how to improve the surface printing effect of heavy packaging carton, how to choose the appropriate printing process and further reduce the carton processing cost. Here we will discuss these aspects.
一、重型包装纸箱的加工工艺
1、 Processing technology of heavy packaging carton
重型包装纸箱的加工工艺主要分为两类。
The processing technology of heavy packaging carton is mainly divided into two categories.
1、全自动重型包装纸箱生产线生产工艺
1. Production technology of automatic heavy packaging carton production line
该重型包装纸箱生产工艺应用得比较广泛，具有生产批量大、纸箱成型体积较大、楞型质量好等优点。该工艺生产出来的重型包装纸箱，通常是通过水性印刷、开槽、粘糊、成型等工序制成纸箱的。以这种工艺生产出的纸箱主要用做运输包装。
The heavy packing carton production process is widely used, and has the advantages of large production batch, large carton forming volume, good corrugated quality and so on. The heavy packaging cartons produced by this process are 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.
2、半自动重型包装纸箱生产线生产工艺
2. Production technology of semi-automatic heavy packaging carton production line
该重型包装纸箱生产工艺是先印刷面纸，再与起好的瓦楞芯纸、纸板进行裱合。该工艺生产出来的重型包装纸箱，常规采用模切压痕、粘钉等工序成箱。该工艺生产出的纸箱成型质量好、表面处理效果好。以折中工艺生产出的纸箱可用做销售包装。
The production process of the heavy packaging carton is to print face paper first, and then mount it with corrugated core paper and paperboard. The heavy packing cartons produced by this process are usually packed into boxes through die-cutting, indentation, nail sticking and other processes. The carton produced by this process has good forming quality and good surface treatment effect. The cartons produced by the compromise process can be used as sales packaging.
二、常规纸箱印刷方式
2、 Conventional carton printing method
常规纸箱印刷方式主要有柔印、胶印和网印三种。
Conventional carton printing methods mainly include flexo printing, offset printing and screen printing.
1、柔性版印刷重型包装纸箱
1. Flexographic printing heavy packing carton
常规的柔性版印刷重型包装纸箱工艺是直接在重型包装纸箱上进行印刷，使用的是水基油墨，因此也有人将该工艺为水印。
The conventional flexographic printing process of heavy packaging carton is to print directly on the heavy packaging carton, using water-based ink. Therefore, some people also use this process as watermark.
柔性版直接印刷具有如下特点：
Flexographic direct printing has the following characteristics:
(1)幅面大，宽幅的柔性版印刷机幅宽可达到2.5~2.8m.
(1) The width of flexographic printing press with large format can reach 2.5 ~ 2.8m
(2)，柔性版耐印力很高，可重复使用;幽默也较。
(2) The price is low, the flexographic printing resistance is very high, and can be reused; Humor is also cheap.
(3)可以联动生产，如印刷、开槽、压痕、订(粘)箱、打捆等一机即可完成。
(3) Can linkage production, such as printing, slotting, indentation, ordering (gluing) boxes, baling and so on.
(4)纸箱强度降比较少。由于柔印是轻压印刷，所以对重型包装纸箱的强度影响很少。
(4) The strength of cartons is reduced less. As flexo printing is light pressure printing, it has little effect on the strength of heavy packaging cartons.
(5)印刷精度不高，常规胶印加网线数为175线/英寸，而柔印纸箱常规加网线数字有35~65线/英寸，属于精度印刷方式，适合印刷文字线条稿，四色图像印刷质量进年来虽有提高，但仍有局限。
(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 ~ 65 lines / inch. It belongs to a low-precision printing method and is suitable for printing text line manuscripts. Although the printing quality of four-color images has been improved in recent years, it is still limited.
(6)制版有易有难，文字线条稿制版容易，四色图像制版难度较大。
(6) Plate making is easy and difficult, text line draft plate making is easy, and four-color image plate making is more difficult.
(7)印刷品质稳定性不好，主要体现为印刷墨色深浅不易控制。
(7) The stability of printing quality is not good, which is mainly reflected in the difficulty in controlling the depth of printing ink.
