The difference between digital printing and traditional printing- Changxing Bocheng Textile Co., Ltd

1. Traditional printing and existing problems

There are many kinds of traditional printing, such as hand printing, flat screen printing, direct printing, discharge printing, resist printing, rotary screen printing and so on. Now, the traditional printing process is quite mature, and the most common ones are rotary screen printing and flat screen printing. Rotary screen printing is a printing method that uses a scraper to print the color paste in the rotary screen onto the fabric under pressure. The rotary screen can only be completed after more than a dozen processes, and can carve very precise fine lines, so It can print delicate and soft patterns (as shown in Figure 1); flat screen printing uses flat screen printing technology, there are three types of manual platen, semi-automatic flat, and fully automatic flat, covering a large area, flat screen printing must not only be accurate Color separation, but also to find out the unit pattern of the cycle, the production speed is slow and the output is low

2 Advantages of digital printing

1. Technical advantages

Since China entered the post-quota era, the textile printing and dyeing, clothing, and home textile industries have become dominant industries. The domestic consumption level has increased significantly, and the opportunities for export trade have increased sharply. In the domestic textile market, "individualization, small batches, fast consumption, and green environmental protection" Labels have become a fashion demand, which is brought about by the introduction of digital printing technology and domestic independent research and development, and at the same time creates unprecedented opportunities for the textile industry. Compared with the traditional printing process, digital printing technology has the following main advantages:

(1) Computer software design pattern

The whole digital digital printing shows that the process from design to production is controlled by computer, the most important thing is pattern design, which is designed by the designer through computer-aided design software, without any restrictions, and can be modified arbitrarily to meet customer satisfaction .

(2) High printing precision

The precision of digital printing can reach more than 2000dpi, and the fineness of the printed image can be comparable to that of a photo, achieving a 3D realistic three-dimensional effect. Digital printing adopts four basic colors CMYK, namely blue-green, magenta, yellow and black, plus 2-4 special colors, namely golden yellow, orange, red and blue, and can print as many as 16.7 million kinds of patterns and colors. Wide color gamut and vivid colors.

(3) Quick response, pursuit of personalization

Digital printing can quickly respond to popular elements, the fashion cycle of clothing is getting shorter and shorter, and the pattern changes are becoming more and more diverse. The emerging fashion patterns can be imitated, redesigned, and produced immediately to meet market demand. ;Consumers can also design their own flower patterns according to fashion trends, tailor-made, or use photography works to pursue a unique psychology.

(4) Small batch production

Digital printing realizes printing from one meter, and truly realizes small batch production. Digital printing does not require color separation and drawing, net making, color matching and other processes, which saves time for customers and reduces printing costs. Customers only need to provide pattern design drafts, free customization, one piece and multiple pieces, one meter kilometer Both are acceptable for production.

(5) Green and environmental protection

Digital printing is mainly controlled by computer, which can achieve "distribution on demand". The printing process does not require water and color paste, and there is no waste of dye and waste water. When the equipment is printing and dyeing, there is no noise pollution, and green production is realized.
