The origin of digital printing
Digital printing technology works basically like inkjet printers, but inkjet printing technology has a much older history, first appearing as early as 1884. After nearly a century of continuous exploration and improvement, the technology began to enter the practical stage in 1960. Digital printing began in 1965 when Carl Helmuth Herthe and Sven Eric Simmons son patented a high-resolution continuous inkjet printer. This continuous inkjet technology uses the opposite electrical charges carried by the droplets to generate finely small droplets under a high-frequency electric field, resulting in high-resolution patterns at visually distinct levels of gray and half-gray.
In the 1990s, human beings began to enter the era of electronic computers. With the popularization of electronic computer technology, the digital printing machine made a breakthrough. In 1995, the drop-on-demand inkjet digital jet printing machine was invented. With the emergence of this technology, the development of digital printing technology began to enter the era of co-existence of heroes and a hundred schools of thought contending.
Features of digital printing
First of all, the workflow of digital printing is greatly simplified and the work cycle is shortened. Compared with the traditional printing process, digital inkjet printing does not require processes such as color separation, sketching, plate making, and matching of color paste. With the aid of the computer, the sample can be directly proofed, and the whole process only takes a few hours. Really achieve the production process of small-batch, multi-variety, and quick response.
Secondly, in the process of dyeing liquid printing in digital inkjet printing, the dyeing liquid is controlled by the internal chip of the machine, and the on-demand inkjet method is used to basically eliminate the waste of dyeing liquid and the discharge of residual liquid. There is no noise pollution during the printing process (<60 dB); the printing of the pattern does not require the preparation of color paste, which avoids the waste of dyes and water, and is generally a clean production process. It gets rid of the shortcomings of high energy consumption and high pollution of traditional printing and creates conditions for green production.
Digital printing has a variety of patterns, and the patterns are more realistic. In the production process of traditional printing, many picture effects cannot be printed due to the limitation of the number of sets of colors and the size of the flower. Such as color gradient transition effect, rich pattern layer effect, and images that require extremely high flower precision. The advent of digital inkjet printing technology has overcome this limitation. Since the original design pattern of digital printing can be modified arbitrarily on the computer and printed out completely by the digital printing machine, it is greatly convenient for designers to bring out their own ideas. Not only the design space of textiles has been expanded, but the grade of products has also been improved.
Finally, inkjet printing is simple to operate and has strong stability. Orders can be received through the Internet, and the whole process is controlled by a computer, which truly achieves "Internet + printing". In the production process of digital inkjet printing, the production data of various fabrics can be recorded by the computer and the corresponding data model can be generated. The establishment of the data model can make the color data unchanged in mass production, and ensure the consistency of small sample and large sample production, and the printing pattern between different batches. This is difficult to achieve in traditional printing. On the other hand, since the production of digital inkjet printing is controlled by a computer system, it can be flexibly produced according to actual needs. For some customers' small-batch products, they can be delivered on the same day of production, which is in line with the rapid response requirements of the market.
