What pre-print is and what post-print is?

Pre-print is to print face paper and then paste it with corrugated roll paper. It uses roll to roll inkjet printing, which is generally a relatively simple unwinding tension winding medium transmission. Post printing refers to direct printing of corrugated board. It requires heavy single sheet feeding and transfer to the receiving system to handle large, thick, heavy but relatively soft paperboard. Paper mounting is a mixture of the two. It is printed on paper and then mounted with corrugated paper. Generally speaking, offset printing is carried out on high gloss paper for high-quality retail boxes or display packaging, so it is called "offset mounting".

One of the advantages of large format inkjet printers is that they can print paper format, which can be much larger than that of the largest offset press. Cartons often used for the largest retail commodities (such as large TVs, lawn mowers, etc.) may need to be mounted with two or more offset papers to cover the whole area, but a large format digital printer can do this.

The first post printing inkjet printer is a UV flat printing equipment with multi-channel nozzle and manual loading or heavy-duty automation system, which can print corrugated board directly. These presses usually perform well, especially because they can provide offset quality directly on paper larger than any offset press. However, the limited use of UV inks around food packaging and multi-channel nozzles means that the throughput of UV plates is low. Even the very fast Inca digital's onset x HS series can only produce 283 full-size paperboards per hour on 3.2x1.6m paper.

In the past decade, we have also fully witnessed the development of high-speed single channel inkjet printers. These printers are equipped with more stable paper feeding devices, and their throughput is much higher than that of UV flat plates. They can process thousands of paperboards per hour.

Post printing is the flexo ink printing machine used in our common carton factory. According to different paper feeding methods, it can be divided into chain machine and leading edge machine, with a large speed difference. The machine speed determines the order output. Therefore, it is suggested that customers should fully consider the order situation when purchasing equipment.

At present, this kind of post printing flexographic ink printing machine is favored by carton factories because of its flexible order and convenient operation. At the same time, we will continuously update and improve the equipment according to the feedback of customers in the process of use.
