There are five kinds of manufacturing methods of heavy corrugated box. Next, we will explain them one by one!

一、单张单面瓦楞纸板→单张胶印彩色面纸→裱合成双面瓦楞纸板→模切开槽→黏合钉箱。这种方式可以印刷出精美的图案，印刷质量高，加网线数可以达到200lpi；制版容易，为PS版常规制版；可以进行表面整饰，如覆膜、上光等，印刷品质稳定；但是，它的生产工序较为复杂，生产周期长，裱合时会使瓦楞纸板强度减小，废品率高，生产场地大，劳动强度高，印刷幅面有限，因而生产成本高，交货期不灵活。

1、 Single sheet single-sided corrugated board → single sheet offset printing color paper → mounting composite double-sided corrugated board → die cutting slotting → bonding nail box. This method can print exquisite patterns with high printing quality, and the number of screening lines can reach 200 LPI; plate making is easy, and it is a conventional plate making for PS plate; surface finishing, such as film covering, glazing, etc., can be carried out, and the printing quality is stable; however, its production process is more complex, and the production cycle is long. When mounting, the strength of corrugated board will be reduced, the scrap rate is high, the production site is large, and the labor cost is low Due to its high strength and limited printing format, it has high production cost and inflexible delivery time.
              

二、单张双面瓦楞纸板→直接柔性版印刷→模切开槽→黏合钉箱。这种方式具有油墨干燥快，印刷速度高，成本较，水性油墨环保等优点，特别适合对瓦楞纸板印刷精美程度要求不是特别高的场合，是目前被采用更多的一种生产方式。但直接柔性版印刷会降瓦楞纸板10％左右的强度。

2、 Single sheet double-sided corrugated board → direct flexographic printing → die cutting slotting → bonding nail box. This method has the advantages of fast ink drying, high printing speed, low cost, water-based ink environmental protection and so on. It is especially suitable for the occasions where the requirement for the printing delicacy of corrugated board is not particularly high. It is a more widely used production method at present. But direct flexographic printing will reduce the strength of corrugated board by about 10%.

三、单张双面微型瓦楞纸板→直接胶印→模切开槽→黏合钉箱。这种方式可以获得微型瓦楞纸板的精美印刷效果，生产周期短，尺寸稳定性好，强度高，定量，楞角清晰，可以用于代替实心纸板生产纸盒和轻型瓦楞纸箱。

3、 Single sheet double-sided micro corrugated board → direct offset printing → die cutting slotting → bonding nail box. In this way, the fine printing effect of micro corrugated board can be obtained, with short production cycle, good dimensional stability, high strength, low ration and clear edge angle. It can be used to replace solid board to produce paper box and light corrugated box.

四、卷筒面纸预印（凹印或柔印）→瓦楞纸板生产线上直接生产彩色瓦楞纸板→电脑纵切→电脑横切→模切开槽→黏合钉箱。这种方式印刷效果精美，瓦楞纸板强度不受影响，生产效率高，成品率高，产品质量好，一般被纸箱厂用于高质量、大批量订单的生产，但这种方式不适合于多品种、小批量订单的生产。

4、 Web pre printing (gravure printing or flexo printing) → direct production of color corrugated board on corrugated board production line → computer longitudinal cutting → computer transverse cutting → die cutting and slotting → bonding nail box. This way of printing effect is exquisite, the strength of corrugated board is not affected, the production efficiency is high, the finished product rate is high, and the product quality is good. Generally, it is used for the production of high quality and large batch orders by the carton factory, but this way is not suitable for the production of multi variety and small batch orders.

五、单张瓦楞纸板→喷墨印刷直接生产彩色瓦楞纸板→电脑纵切→电脑横切→模切开槽→黏合钉箱。这是才刚应用的一种全电脑控制的生产模式，设计图稿无须分色、制版、多色套印等复杂工序，可以立即实现所设计图稿在瓦楞纸板上的多色印刷，大大缩短了纸箱厂的生产周期，特别适合于多品种的生产。但是，目前由于这种大幅面的喷墨印刷机还需进口，一次投资较大，喷墨用油墨较贵，因此目前应用此方式的纸箱厂数量并不多。

5、 Single sheet corrugated board → inkjet printing direct production of color corrugated board → computer longitudinal cutting → computer transverse cutting → die cutting slotting → bonding nail box. This is an advanced production mode with full computer control, which has just been applied. The design drawings need no complicated processes such as color separation, plate making and multi-color overprint. It can realize the multi-color printing of the designed drawings on the corrugated board immediately, greatly shortening the production cycle of the carton factory, especially suitable for the production of various varieties. However, at present, due to the large format inkjet printing press still needs to be imported, a large investment, inkjet ink is more expensive, so there are not many carton factories using this method.
