Several common printing corrugated box comparison
Corrugated cartons with our lives, inextricably linked to the production of a plain paper packaging products, corrugated boxes printed corrugated box quality not only related to the appearance of quality, but also affect the sales prospects of the packaging and commodity production corporate image. Therefore, how to improve the effect of corrugated surface printing, how to choose a good suitable printing process, to further reduce the carton processing cost analysis of such issues is particularly important. Here we will be discussing these areas.
A corrugated board corrugated board processing technology is divided into two types of processing technology
1. Automatic corrugated cardboard production line corrugated cardboard production process of the application of the process was more extensive, with large-volume production, carton forming larger, corrugation and good quality. The process produced corrugated board, usually by water-based printing, slotting, Zhan Hu, made of carton forming and other processes. In this process to produce carton packaging, primarily used for transportation.
2. Semi-automatic production line corrugated cardboard production process of the corrugated board production process is the first printed tissue paper, then with corrugated paper and cardboard were pasted together. The process produced corrugated board, routine use of die indentation, the processes of nails sticking into me. The process to produce good quality carton forming, surface treatment effect is good. In this technique can be used to produce carton packaging sales.
Second, the conventional printing of conventional cardboard cartons mainly flexo printing, offset and screen printing of three
1. Flexible printing corrugated conventional corrugated flexo printing process is carried out directly on the corrugated board printing, using a water-based ink, so the process was also known as the watermark. Flexo printing directly has the following characteristics:
(1), large format. Flexible Printing Machine Wide maximum width up to 2.5m ~ 2.8m.
(2) low price. Flexible printed-resistant high strength can be repeated use; ink prices lower.
(3) can be linked production, such as printing, slotting, creasing, set (stick) cartons, strapping, etc. to complete a machine.
(4) reduce the carton less intensity. Because of the soft reduction flexo printing, so little effect on the strength of corrugated board.
(5) printing accuracy is not high, the conventional offset printing line screens of 175 lines / inch, while flexo carton of conventional screening line figures 35 lines / inch to 65 lines / inch, a low-precision printing, most suitable for printing text line art, four-color image printing quality despite increase in recent years, but still limited.
(6) plate are easy to trouble, line art plate making writing easy, four-color image plate difficult.
(7) the stability of the printing quality is not good, mainly reflected in the printing ink shades not easily controlled. Flexo printing technology directly applicable to the production process first carton, carton plant in China currently applied is very wide.
2. Offset printing corrugated cardboard boxes using conventional offset printing is an indirect printing methods, namely, printed cartons tissue paper first, then mounting of printed tissue paper to corrugated board.
