Digital printing technology is a general term encompassing inkjet printing techniques, which have become more widely adopted in the textile industry compared to traditional printing and dyeing methods. As customer demands continue to diversify, the business of printing on greige fabrics or garments has shifted from large-scale production toward smaller batches, greater variety, and personalized customization. Digital printing technology not only delivers high-quality printing results but also effectively meets customers' needs for small-batch, customized prints. Only flexible and adaptable printing enterprises can sustain continuous growth amid fierce market competition.

As an emerging printing method, digital printing technology has gained prominence due to its high efficiency, low sampling costs, excellent print quality, and minimal environmental impact. These advantages effectively meet the increasingly diverse demands of the market, thereby enhancing the diversity of the textile printing and dyeing industry...

Overview of the Development of Digital Printing

Today, environmental policies are becoming increasingly stringent, placing significant challenges on the traditional printing and dyeing industry. According to statistics from relevant authorities, China's printing and dyeing wastewater discharges reach 3 to 4 million cubic meters daily, accounting for 35% of the nation's total industrial wastewater output. As a result, the traditional printing and dyeing sector has become a key focus area for national energy conservation and emission reduction efforts. Indeed, its environmental impact has already begun to hinder the industry's sustainable development. In contrast, traditional printing methods typically see about 30% of dyes fail to bond with fibers, leading to substantial wastewater generation after washing. By contrast, digital printing technology is far more energy-efficient, using only 40% of the dye required by conventional processes. Moreover, it produces just 5% of the "floating color" seen in traditional techniques, resulting in wastewater volumes that are merely 1/15th to 1/25th of those generated by conventional methods. Additionally, the overall energy consumption associated with digital printing is approximately one-third to one-quarter of that of traditional processes. Clearly, the economic and social benefits brought about by digital printing will have a profound impact on China's textile printing and dyeing industry, paving the way for a more sustainable and environmentally friendly future.

However, digital printing cannot completely replace traditional printing and dyeing techniques. Although digital printing has been developing in China for about 20 years, despite the country's consistent emphasis on phasing out outdated production capacities, it has yet to fully supplant traditional methods. This situation can be attributed to two primary reasons. First, while digital printing offers significant cost advantages for small-batch production—far surpassing those of traditional printing—the relatively high cost of its ink compared to conventional color pastes makes it less economical for large-scale manufacturing. Second, traditional printing relies on spot-color processes, where each specific shade is precisely matched using accurately formulated color pastes. In contrast, digital printing produces colors by mixing CMYK inks. Variations in ink quality, differences among print heads, and even minor environmental fluctuations during the printing process can all compromise the accuracy of the final mixed colors.

The Advantages of Digital Printing

In textile printing, although digital printing technology still faces challenges in achieving certain effects compared to traditional printing and dyeing techniques, it is undeniable that digital printing, with its unique technical advantages, is transforming the production methods of printed products and is increasingly being applied in soft signage advertising. Specifically, the advantages of digital printing technology are evident in the following aspects:

1. Vibrant colors, clear patterns, and high printing precision

2. Short production cycles and rapid response times—no need for plate-making, offering flexible batch production without limitations on design patterns. Additionally, images can be freely modified at any stage. Whether it’s sampling, small-batch production, or large-scale manufacturing, delivery is always prompt and efficient.

3. Low energy consumption, low pollution, and low noise—this technology produces no wastewater during the entire printing process and operates with minimal noise, making it a truly sustainable production method.

4. Ideal for personalized customization, digital inkjet printing requires minimal space and can be carried out in both office and home settings. Personalized digital printing can also be realized through the internet.

Digital printing drives the transformation and upgrading of traditional printing techniques.

It is understood that European textile printing and dyeing enterprises have already ceased expanding their traditional printing and dyeing processing capacities. Among these, flat-screen printing, characterized by its complex operations and slow production speed, has largely been phased out. Meanwhile, rotary screen printing, owing to its faster production rate and lower costs, still maintains some operational presence in certain enterprises. However, with the continuous advancement of high-speed digital printing technologies, the market share of traditional printing methods is steadily shrinking. Today, nearly all newly added printing capacity in Europe and North America comes exclusively from digital printing solutions. In recent years, driven by rapid technological advancements, China's textile digital printing technology has reached maturity, with significant improvements in both output and efficiency. Digital printing plays a crucial role in facilitating the industry's transition toward greener and more sustainable practices. By significantly reducing wastewater generation during the printing process—thanks to minimized waste from screen cleaning—and cutting chemical usage and waste by up to 80%, digital printing aligns perfectly with the principles of clean production. Moreover, this innovative technology not only enhances the efficiency and environmental friendliness of the dyeing and finishing industry but also makes it more technologically advanced, versatile, and adaptable to evolving market demands.
