There are obvious differences between digital printing and traditional printing in many aspects. First, digital printing can complete high-quality images in a very short period of time, while traditional printing usually takes more time and steps. Second, digital printing can be produced according to customer needs, while traditional printing requires a lot of pre-printing and inventory. In addition, digital printing is more environmentally friendly, reducing the pollution to the environment, while traditional printing may discharge waste water and waste gas in the production process. Finally, digital prints can also offer a richer choice of patterns, being more stylish and personalized, while traditional prints are limited by fixed patterns and sizes.
What are the characteristics of digital printing?
Digital printing has the characteristics of high speed, high accuracy, no material restrictions and environmental protection. First, the process of digital printing can be completed quickly through digital technology, unlike traditional printing, which requires tedious steps and long waits. Secondly, digital printing can provide high precision printing effect, whether it is the color of the reduction degree or the image details, can reach a very high level. Moreover, digital printing is not limited by the material, whether the fabric, paper or metal can be printed, a wide range of applications. Finally, digital printing has less impact on the environment in the production process and pays more attention to environmental protection. These are the unique features of digital printing that make it highly competitive in various applications.
What is the application prospect of digital printing in the market?
As a new printing technology, digital printing has shown a broad application prospect in the market. With consumers pursuit of individuation and fashion, digital printing has the advantages of fast speed, flexibility, high precision and low cost, which makes it gradually become textile printin gNew trends in the field. Not only that, the application field of digital printing is also gradually expanding, and now it has covered fashion, home furnishing, advertising and other fields. It can be predicted that, with the continuous progress of science and technology and the growing market, digital printing will play an important role in the future market competition.
How to further develop the digital printing technology?
Digital printing technology can be further developed to achieve greater efficiency and greater flexibility. With technological advances and material innovations, this technology may be more and more used in business and fashion in the future. We need to actively focus on innovative technologies and strengthen research and development to improve the numbers calico printing machine Speed, lower costs, and better quality control.
On the other hand, we also need to pay more attention to environmental issues to ensure that digital printing does not have too much impact on the environment. Research and development of more environmentally friendly, sustainable materials, and optimize the energy utilization of digital printing machine, will become an important direction of digital printing technology development in the future. In addition, government departments can consider providing more policy and financial support to encourage and support the development and application of digital printing technology.
What are the innovative technologies of digital printing?
At present, the innovative technology of digital printing includes the following aspects:
1.Thermal transfer technology: Using the heating method, transfer the patterns or text from the printed materials to other materials, such as fabrics, ceramics, wood, etc. This technology is suitable for objects of various shapes and materials, and can be applied to personalized gift making, home decoration and other fields.
2.Inkjet printingTechnology: Imare formed by spraying ink onto surfaces of paper, fabric, etc. This technology has high precision, fast speed, environmental protection, and a wide range of application, and can be applied to clothing, shoes and hats, bags, wallpaper and other fields.
3. Printing technology: print patterns or text on paper, cloth and other carriers, and then apply them to other items through various means (such as cutting, splicing, folding, etc.). This technology can be applied in gift packaging, stationery, home decoration and other fields.
4. 3D printing technology: utilization three dimension scanning Technology obtains three-dimensional data on the surface of an object, which is then converted into material ejected from a computer-controlled nozzle to form a three-dimensional image. This technology can be applied to art, architecture and decoration.
5.Electric spinning Technology: through Electrospinning technology, Can produce nanoscale fiber materials, which can be printed on the surface of fabric, paper and so on, forming high precision, high transparency patterns or text. This technology can be applied to advanced cosmetics, electronic product packaging, decorative materials and other fields.
These innovative technologies have brought more possibilities and innovation space for digital printing, and promoted the rapid development of the digital printing industry.
Process control of digital printing
The inkjet printing process mainly includes textile pretreatment, drying, printing, drying, steam steam (120℃ 8min, make the active dye solid color), washing, drying and other processes. Before printing, in order to improve the wetting, adhesion and curing effect of the fiber and ink on the textile surface, while preventing the penetration of the ink, this is called pretreatment or preliminary treatment.
(1) Pretreatment of the bearing material
For non-permeable or poor permeability, ester is required to reduce the spreading effect of ink on its surface; For bearing materials with good permeability, higher pseudoplastic polymer or thickener is required to avoid horizontal suction along the yarn direction when the ink is fixed on the fiber.
In order to improve the final printing quality and meet the suitability requirements of the subsequent printing process, textiles should be treated early before inkjet printing. The following mainly discusses the pretreatment measures in the inkjet printing process from several common textile materials.
1. Pretreatment of cotton fabric
Cotton textiles have the advantages of soft luster, soft texture, durability and good color, etc. They are used first in the traditional printing process, and their process is the most perfect and mature. Therefore, as long as the textile is to ensure that its printing suitability meets the special requirements brought by the different inkjet printing and traditional printing process.
uch as inkjet printing process, ink to the cotton textile surface transfer way is through the form of spray nozzle, so in the early printing in the cotton textile surface preauxiliary (slurry) added thickening agent sodium alginate, in order to suppress the spray on the cotton fabric ink diffusion, improve the accuracy of cotton textile printing. At the same time, it is also necessary to ensure that the alkaline environment when the textile surface fiber is combined with the ink and the temperature and humidity of the printing workshop are within a certain range (generally, the temperature of the inkjet printing is required to keep at 18~25℃℃, and the relative humidity is greater than 50%)
