The plate-making process is simple, the cost is low, the production efficiency is high, the pattern is exquisite and the quality is stable.

2. Flexographic printing process.

Flexo is a way of direct printing with a short ink path. The plate is made of resin with certain elasticity, the picture and text part is raised, the blank part is concave, the ink supply device of scraper and netting roller is used, and the environmentally friendly water-based ink is used for production.

On-demand, timeliness, and variability are the characteristics of digital printing. But its printing quality is not lower than the traditional printing technology, much higher than the printing technology.

Whenever productivity is improved, or the emergence of new printing materials, new products, people have a further aesthetic consciousness, it will promote printing to take a qualitative leap.

Printing is always closely related to people’s lives, for example, for a long time in history, people used local materials to print goods. At first, using relatively large plant leaves, such as plantain and lotus leaves, was the first choice for people to wrap things at that time. When the textile technology has been improved, people often use cloth or satin for packaging according to the occasion of use. With the further development of productive forces, there is a more professional, similar to the current packaging printing factory of some workshops, printing also has a more detailed classification. For example, exquisite boxes for jewelry, boxes for different styles of fat powder, containers for all kinds of wine, and so on. Not only the appearance is different, but the material is also very different.

In modern society, printing has changed with each passing day in order to comply with the trend of the times, which puts forward more and higher requirements for printing companies.

1. Advocate green environmental protection.

For example, the use of recyclable ecological paper, specific pollution-free pigments, and so on.

 

2. It is required to highlight the individual characteristics of the goods, resulting in visual impact.

Nowadays, there are a lot of electronic goods, and e-commerce is also very developed. When printing, we should consider moistureproof, anti-extrusion, anti-impact, and so on. Because of the popularity of e-commerce, the convenience of transportation should also be taken into account in modern society.
