What is digital printing? In today's world of personalization and convenience, on-demand printing and variable data printing have ushered in a new era of development. With its incomparable advantages over traditional printing, digital printing has thrived in these "emerging" markets.

From the beginning of design, traditional printing has to go through many steps, such as color separation, proofing and plate making, before printing can be done on the machine. Not only that, traditional printing has certain requirements for the initial print volume, and variable data printing is simply impossible to achieve under traditional processes. Digital printing not only has a simple printing process, but the designed and produced files can be directly transferred to the digital printing machine, and there are fewer intermediate links in printing, and the variable factors generated are reduced accordingly. As long as color management is done well, printing in different places at different times can completely save costs and time while ensuring the consistency of printing quality. What is even more valuable is that digital printing makes short-run printing, on-demand printing, and data printing a reality.

The following is an analysis and popularization of the characteristics and challenges of digital printing bag making machines for readers:

Challenges

1. Adjust the machine in the shortest time and with the least material consumption

1. Learn about the three elements of bag making: temperature, hot sealing pressure, and hot pressing time;

2. Material feeding method (Web Path);

3. Tool replacement time (hot knife, mold);

4. Maintenance or replacement time of wearing parts (flying knife, die mouth oiling).

2. How to make a beautiful bag?

▶Preparation

1. Hot knife angle guide, zipper point hot block angle guide, in order to prevent burrs;

2. Stick Teflon tape and cloth on the hot knife, especially pay attention to the above treatment on the cooling knife;

3. Tool test (cutting knife, flying blade and die cutting board sharpness test).

▶ Finished product inspection

1. Random inspection during production: horizontal seal, vertical seal, zipper, punching, keep the error within ±1 mm;

2. The inspection laboratory will conduct air filling in the bag, water bath test and drop test according to the bag type requirements.

Next, I will introduce the features of Zhoutai digital printing bag making machine:
