Everything Is Beautiful: The More Beautiful The Digital Printing Is, The More Beautiful It Is.

With the change of the times and the change of consumption pattern, the development of many traditional silk enterprises is difficult. However, looking back on the recent development of Wan Shi Li group, we can see another scene: participation in the Beijing Olympic Games, Shanghai World Expo, Guangzhou Asian Games and APEC meeting, and the acquisition of the international market. brand Invite Hermes Top executives have boundless scenery in the domestic and international arena.

There are many reasons for the success of Wan Shi Li, with advanced digital technology. Printing technology Achieving flexible production is one of its core factors. Ma Tingfang, general manager of Wan Shi Li Silk Technology Co., Ltd. emphasizes this.

　 1 leading to launch "digital printing" research

Nowadays, with its low pollution, low consumption, high added value and flexible production characteristics, digital printing has attracted many enterprises to invest. However, back to more than ten years ago, the situation of digital printing in the domestic market was very embarrassed, almost no one was interested in it.

"At that time, the price cost of digital printing was prohibitive for many enterprises, but the traditional silk printing process is long, the technology is difficult, energy consumption and electricity consumption, and the problem of waste water can not be avoided. The appearance of digital printing just made up for the shortcomings and defects of traditional silk printing. So no matter what price we pay, we must deal with it. " Ma Tingfang said. In 2005, Wan Shi Li decided to develop digital printing technology.

However, due to the restriction of the speed of the digital printing machine in the early years, in the first few years before the start of the project, Wan Shi Li always failed to meet the requirements of fabric industrialization. "And the principle of traditional printing and digital printing is completely different. To create the same color and pattern, it is a great challenge for the company's technical team." Ma Tingfang recalled.

However, Kung Fu's commitment to digital printing was finally realized in 2008. Ma Tingfang said: "after a lot of in-depth research, the company's technical personnel, from the improvement of color separation technology, adjustment of printing parameters and ink screening, have finally solved the major technical problem of digital color simulation, and combined with the improvement and improvement of a series of process technologies, making digital printing large scale customization become industrialized."

At present, the technology of digital printing has matured and output has increased greatly. Speed is no longer the shackle of the technology. In 2014, the Xiasha Industrial Park was set up and put into use in the production, sightseeing, education and tourism of silk industry. Now, at this base, hundreds of advanced digital printing machines at home and abroad, such as Italy Meichi, Japan's EPSON and Hangzhou Honghua, are working methodically.

It is understood that the annual output of silk printing fabric can reach 9 million square meters. The huge capacity can meet the production needs of the company and the processing of foreign enterprises.

2 advance environmental protection and reduce costs

All over the country, in the wake of the distress of printing and dyeing, environmental protection consciousness and reasonable pollution discharge have made the pace of development unstoppable. In the factory of Xiasha Park, there is not a little sewage on the ground after hardening, and the environment in the workshop is clean and tidy.

"This project uses low waste silk digital printing technology." According to Ma Tingfang, compared with traditional printing and dyeing technology, the technology consumes 30% of dye consumption, reduces water consumption by 85%, reduces power consumption by 45%, reduces unit water treatment cost by 30%, and recycles waste water. The comprehensive energy consumption per 10000 yuan output is only 1/10 of traditional printing.

Ma Tingfang said that the whole production process of silk products should be green. "Printing and dyeing wastewater has the characteristics of large quantity of water, poor biodegradability, high salt content, high chromaticity and large fluctuation of water quality. With the increasing rigid constraints of resources and environment, printing and dyeing enterprises must face the path of environmental protection and develop vigorously and bravely, and only through self renovation of high technology content can we have a way out for spanformation and upgrading. He said.

It is reported that nowadays, the low waste silk digital printing technology developed by Wan Shi Li covers almost all of the silk products, such as silk garments, scarves, neckties, and even silk home textiles, such as bedding, curtains, bags, pendants and so on. All of them have the appearance of digital printing. At the same time, they have brought double harvest to the sales and profits of all things. According to the annual report, in 2015, sales of Wan Shi Li group increased by 11% compared with the same period last year, and the profit increased by 10% compared with the same period last year, of which the sales of silk plates increased by 12% compared to the same period last year, and the profit grew by 26% over the same period last year.

　 3 solve color management problems

It is undeniable that although companies generally believe that the digital printing machine has fast response speed, low proofing cost and good consistency, there are still many problems to be solved in digital printing for silk fabrics.

For example, compared to the traditional printing of spot color printing, digital printing is CMYK mixed color printing, all colors are mixed by four color ink, a little bit of external changes, such as the difference of ink, printhead difference, printing environment changes, will affect the accuracy of a series of colors.

"Before, there were many traditional printing patterns requiring the production of digital printing. The principle of traditional printing and digital printing is quite different. It is more difficult to create identical colors and patterns. After 2008, the technical personnel of the company began to solve this major technical problem from the following aspects: improving the draft technology, adjusting the parameters of inkjet printing and screening the ink. Ma Tingfang recalls.

"The company started research at the end of 2013. In May 2014, it hired a team from the school of digital media and art design, Hangzhou Dianzi University, to conduct cross boundary cooperation for digital printing color management projects, and focus on the" color management simulation system "to ensure that the color reduction reaches more than 95%. Ma TING FANG proudly said.

It is understood that through 2 years of extensive tests and tests, Wan Shi Li has gradually improved the links that are likely to cause color loss in the digital printing process, and added data to the loss of parts of each process into the management system to achieve the goal of "WYSIWYG".

"Wan Shi Li" is the first company in China to carry out color management in the whole process of textile digital printing. From the original color adjustment to the color to adjust the number. In this way, the coloring machine can quickly and accurately color the computer. In addition, we have achieved different types of color matching. " Ma Tingfang added that in general, different equipment has different colors due to different nozzle, ink and management software. But through the implementation of color management, Wan Shi Li can match the color of two different devices, and print products with the same color.

Of course, we need to develop the color management system thoroughly, and we must note that every printing process (such as beating, sizing, steaming, washing, finishing, etc.) must be carried out with stricter standardized operation. Color management is a dynamic process. It must be adjusted continuously with the change of production conditions. To give a simple example, the display screen and scanner should be corrected at least once a month. Ma Tingfang said.
