Problems And Trends In The Development Of Digital Printing

< p > digital printing will replace traditional printing in the future. In recent years, the technology of digital inkjet printing has matured, and the output of digital printing has also increased significantly. The development of digital printing technology is increasing rapidly, and speed is no longer the bottleneck of digital printing.

Now digital printing has gradually entered the growth stage, but the printing speed is only one of the factors of growth. There are still many related problems to be solved.

Many people say that digital printing instead of traditional printing is only a matter of time. Is this really the case? In particular, two experts from Taiwan WIKO group, Chen Xiaoshan and Chen Wenzheng, invited to discuss the problems and trends of digital printing development.

< /p >

< p > Q: the industry has always said that digital printing belongs to the new technology, and has obvious advantages. What is the biggest difference between digital printing and traditional printing? What kind of technical advantages do they have? < /p >

< p > Chen Xiaoshan: the traditional a target= "_blank" href= "http://www.91se91.com/" > textile < /a > printing, is to use the screen to print the colors one after another, the more the color needs more screen, the more complicated the homework is, but even though there are many screen prints, the printed patterns are quite monotonous, unable to see the color gradation, high resolution landscape images and the real color of the characters.

In addition to the complexity and printing effect of printing technology, printing production process is lengthy, and from production to sale takes more than 4 months. The production of screen printing takes 1~2 months. The production process requires more manpower, time and energy. After the production, screen printing and equipment cleaning also need to consume a considerable amount of water resources.

< /p >

< p > Chen Wenzheng: digital printing technology has broken through the bottleneck of textile printing. With the combination of image processing software, inkjet printing machine, inkjet printer and jet printing substrate processing, the real image or pattern of digital storage can be directly printed on the fabric, with the diversity of pattern design and color change. It is widely used in fashion design and fashion < a target= "_blank" href= "http://www.91se91.com/" > dress < /a > industry.

It is especially suitable for small quantity and customized production processes, greatly reducing the operating cost of screen printing 50% in time 60%, and greatly reducing the overall production time and responding to the needs of customers quickly.

At the same time, the output of waste water caused by screen cleaning has been reduced, and 80% of the provincial medicine has been cut down, which is in line with the needs of cleaner production. Digital textile printing technology has made dyeing and finishing industry more scientific, environmentally friendly, faster and more diversified.

< /p >

< p > Q: what is the application of digital printing technology in the world? < /p >

< p > Chen Xiaoshan: now digital printing products account for more than 30% of the total domestic printing volume in Italy. The growth rate of digital printing lies in the industrial structure and cost. Italy is a popular market oriented by printing design. Most of the high-end printed textiles in the world come from Italy.

< /p >

< p > in terms of printing production costs in Italy, the cost of producing 400 meters of small quantities of products is nearly two euros per square meter, while the same batch of products in Turkey and China cost less than 1 euros; if the small batch production of 800~1200 meters is nearly 1 euros per square meter, the cost difference makes digital printing become the mainstream, so digital printing can meet its market demand.

< /p >

< p > in addition, in terms of cost structure, traditional printing needs to be prepared in small batch production, which makes the initial cost of traditional printing relatively high, but with the increase of printing cost, the cost of mass production is relatively low.

< /p >

< p > for digital printing, the main cost comes from the sprinkler and ink. No matter big or small batch production costs are similar, as long as the printing speed is fast enough, the management cost will be relatively low, which is also the development concept of the equipment manufacturer's high-speed machine.

< /p >

< p > Chen Wenzheng: according to data statistics, the traditional printing in the world is mainly concentrated in the Asian region, including China, Southeast Asia and India, accounting for 66% of the total printing volume.

< /p >

< p > China accounts for nearly 30% of the world's output in traditional printing, but digital printing is still less than 1% of the country's printing volume.

< /p >

< p > Q: sprinklers and ink are very important for digital printing. Where is the importance of ink? < /p >

< p > Chen Xiaoshan: if the nozzle is the engine of digital inkjet printing, ink is the fuel of digital inkjet printing. Without fuel, there will be no good equipment system.

< /p >

< p > the ink quality is good, the consumption of the nozzle will be reduced, the service life of the sprinkler will increase naturally, and the ink quality will not only hurt the sprinkler head, but even affect the printing and stopping.

< /p >

< p > ink consists of colorants, moisturizers, surfactants, fungicides, and other additives. Pigments are the key to the achievement of printing colors. With good pigments, the ink quality is half successful. The other half depends on the combination of solvent formulations to enhance printability.

< /p >

< p > Chen Wenzheng: WIKO has developed digital textile printing ink for more than 10 years. It has been adjusted by technology, product verification, customer testing and product promotion. It has been successfully developed reactive color R series and acid color A series products at the present stage.

< /p >

< p > WIKO's development strategy for digital textile printing is to follow the development of sprinkler technology and customer needs, and continuously introduce products that meet the needs of the market.

< /p >

< p > Q: digital printing has been developing in China for some years. Although it has been widely praised, it has not replaced the traditional printing method. What do you think is the bottleneck in the development of digital printing? < /p >

< p > Chen Xiaoshan: digital printing is an integrated technology that requires sprinklers to match with inkjet printing equipment, ink, printing software and fabric front and back processing.

For sprinklers and jet printing equipment, the warranty period of industrial sprinklers is generally six months to one year. For printing industry, the driving engine (sprinkler) is consumable and the cost is considerable. The equipment designed by multiple sprinklers also has potential risks. If one of the nozzles has problems in the printing process, it will cause losses. In addition, industrial sprayer manufacturers hope to extract the cost of the nozzle maintenance from equipment manufacturers and ink merchants, which also increases the cost of ink consumables.

< /p >

< p > secondly, for the ink manufacturers, because of the continuous introduction of new sprinklers and the application of different fabrics, it is necessary to develop special ink suitable for all kinds of sprinklers and all kinds of fabrics. However, most ink stains are derived from existing traditional pigments, and may not meet the requirements. In addition, products must also consider diversification and color rendering, which is more complex and difficult for end users.

< /p >

< p > third is software. Today's software has a high cost for most of the end users, and different color printing equipment, ink and fabrics need to be remade, which is more complicated than traditional printing.

< /p >

< p > finally, fabric processing. Digital printing is different from ordinary paper printing. Fabric needs to be processed before and after processing to make the fabric color. Although the fabric pretreatment is not new to the traditional printing plant, it is the key to digital printing. Only print that the customer needs can print its value.

If there are problems in the pretreatment and steaming links, all the results will be wasted.

< /p >

< p > Chen Wenzheng: because the traditional printing companies are not familiar with the technology of digital printing, and the traditional digital operators must change their thinking, including the operation mode and environmental control.

In addition to equipment, ink, software and fabric processing, the most important thing is to familiarize yourself with manipulating equipment and familiar with pre and post processing talents.

Digital printing started in the market only 15 years ago. It has been 2~3 years since it became truly industrialized. How to cultivate people who are familiar with inkjet printing and printing technology is the key. Only when more and more talents are trained and invested, will the industry have the opportunity to thrive, but it will take a long time to invest.

Digital printing is a new technology that integrates many technologies. Most of the printing companies are not familiar with the equipment, so at this stage, most of them are still engaged in the integration of equipment business. But the equipment manufacturer hopes to include the equipment, software and ink. This is what the printing factory does not expect to see, but also restricts the development of digital printing. Therefore, the differences between concepts and restrictions of technology cause the bottleneck that digital printing can not flourish.

< /p >

< p > Q: what is the future trend of digital printing? < /p >

< p > Chen Xiaoshan: today's textile printing, popular elements are changing rapidly, requiring more design, shorter order code, more complex design, higher fastness, environmental awareness, tolerance of color variation and fabric specifications.

To this end, digital printing will meet the above requirements, and more sprinklers and equipment dealers, inks, software vendors and printing companies will invest in the future.

< /p >

< p > Chen Wenzheng: the reliability and durability of the sprinkler is the focus of the development of the sprinkler manufacturers, because the average life cycle of the sprinklers is not more than one year, which is quite high for printing. Therefore, the design of the new sprinkler is designed in the direction of internal circulation and maintainability besides the increase of the number of nozzle holes, and it is hoped to prolong the service life of the sprinkler.

< /p >

< p > equipment manufacturers will also start with improving the stability and ease of operation of equipment. The form of equipment bound ink will be broken, and equipment integrators will slowly advance in the direction of providing equipment and maintenance services.

< /p >

Except for the continuous development of more kinds of ink products, the ink manufacturers need to develop the ink products that enhance the coloring and apply to all kinds of fabrics. The ink cost will gradually be reduced due to the growth of the market in the ink cost. P

< /p >

In the future, more software developers will develop more easy to use software for P and printing factories.

< /p >

< p > a href= "http://www.91se91.com/news/index_c.asp" > printing company < /a > requires continuous training of talents, and enables operators to improve their professional skills in digital printing and learn to independently control the ability of digital printing equipment and ink. Only in this way can digital printing technology get faster and better development.
