The working principle of digital printing is basically the same as that of inkjet printers, and inkjet printing technology can be traced back to 1884. In 1960, inkjet printing technology entered the practical stage. In the 1990s, computer technology began to popularize, and in 1995, on-demand inkjet digital printing machines appeared. The development of digital printing technology is showing a trend of rising stars and blooming flowers. The technology involved in digital printing is becoming increasingly sophisticated, including various types of heat transfer printing, direct printing, etc. In recent years, China's textile printing and dyeing industry has developed rapidly, and the printing output has also increased synchronously. At the same time, the fashion cycle is becoming shorter and shorter, pattern changes are becoming faster, production requirements are becoming higher, order quantities are getting smaller, and pattern piracy is rampant. Although printing companies have introduced digital methods such as printing CAD systems, laser typesetting machines, flat and circular inkjet printing, and wax spraying machines to improve the processing of traditional printing methods, the concept that printing and dyeing factories are polluting factories seems to have left a deep impression on people. Later, a textile technology company in Shanghai introduced this technology with its advanced production principles and process technology, bringing unprecedented development opportunities to textile printing and dyeing. At the same time, the export of China's printing and dyeing products is increasingly hindered by "non trade barriers", including environmental factors, internationally. Technically speaking, digital printing is the best way to solve many problems in the printing field. Digital printing refers to printing using digital technology. Digital printing technology is a high-tech product gradually formed with the continuous development of computer technology. Traditional printing cannot do without a flat or round screen, but the cost and time required for plate making cannot meet the trend of small batch and multi variety printing. Therefore, digital printing without plates and pressure has been developed.

The production process of digital printing is simply described as inputting various digital patterns into a computer through various digital means such as scanning, digital photos, images, or computer processing. After being processed by a computer color separation printing system, specialized RIP software directly sprays various specialized dyes (active, dispersed, acidic main coatings) onto various fabrics or other media through its printing system. After processing, high-precision printing products are obtained on various textile fabrics. Compared with traditional printing and dyeing processes, it has the following advantages:

1.The production process of digital printing greatly shortens the original process route, increases order acceptance speed, and greatly reduces sampling costs.

Due to the production process of digital printing breaking away from the traditional printing process of color separation, drafting, film making, and mesh making, the production time is greatly shortened. The way to accept patterns can be through various advanced means such as CDs, emails, etc. Generally, the sampling time does not exceed one working day, while the traditional sampling cycle is usually around one week.

In addition, the simplification of the process greatly reduces the cost of sampling. The shortening of the sampling cycle and the reduction of sampling costs, in today's market competition where time is money and efficiency is life, undoubtedly bring more market opportunities to enterprises.

2.The principle of digital printing technology enables its products to break through the limitations of traditional color matching and flower length in production, and can achieve high-end printing effects on textile fabrics.

Due to the fact that digital printing technology can use digital patterns for color measurement, matching, and printing through computers, the colors of digital printed products can theoretically reach 16.7 million, breaking through the color matching limitations of traditional textile printing and dyeing patterns. Especially in the printing of high-precision patterns such as color gradients and cloud patterns, digital printing has unparalleled advantages in technology. In addition, traditional printing patterns are often limited by the length of the "flower loop", while the concept of "flower loop" can be eliminated in the digital printing process, greatly expanding the space for textile pattern design and enhancing the product's grade.

3. Digital printing production truly realizes the production process of small batches and fast reactions, with no restrictions on production batches.

Due to the computerization of the digital printing production process, the flexibility of production has been greatly improved, and some products can even be delivered on the same day, making them readily available. In addition, due to the application of computer technology, printing a series of patterns with different tones of the same pattern, as well as designers constantly modifying the colors of the patterns during the production process, has become a major technological advantage of digital printing production compared to traditional printing production.

4. The high-precision printing process eliminates the need for water or ink during the printing process.

The use of dyes in the printing process is "distributed according to demand" by the computer, so that there is no waste of dyes and chemicals, no wastewater is generated during the printing process. The computer-controlled printing process does not produce noise, so there is no pollution during the printing process, realizing a green production process. This has enabled the production of textile printing to break away from the high energy consumption, high pollution, and high noise production processes of the past, and achieve a low-energy consumption and pollution-free production process, bringing a technological revolution to the production of textile printing and dyeing.
