What is digital printing and what are the advantages of digital printing?

The advantages of digital printing are:

Fast response time:

With its fast proofing, the digital printing machine can improve the response speed of enterprises to orders. In the market, the competition of leading printing enterprises has intensified, the processing has declined, and the profit margin has declined.

Cost reduction: Proofing with a digital printing machine can replace part of the work that has to be done on a rotary screen and flat screen printing machine without taking up machine time. Proofing usually takes 3-4 hours by machine.

If the customer is not satisfied, it will be repeatedly modified, resulting in a great waste of production capacity.

Wide range of applications:

The inks that can be used for proofing by the digital printing machine include active ink, acid ink, and disperse ink, which can be used for sample printing. Direct printing with dispersed inks is still looking for the right ink.

In the customer's sample, if it is paper or electronic, it can be proofread with a digital printer directly after color separation. Traditional printers can complete mass production according to the proofing effect.

Checked on the Internet, there is a paragraph below, I hope you can have an understanding of the technical characteristics of Shanghai Yishu digital printing **** printing processing on digital printing:

1) Compared with the traditional printing process, the printing process of the digital jet printing system has been fundamentally changed, and the process flow is design, printing, and post-processing, which saves the installation of drawing, film production (or net making, engraving), screen (or rotary screen), and simplifies the process of equipment commissioning and slurrying; It also simplifies equipment such as the filmmaker (or screen making machine, engraving machine) and consumable materials such as film, wire screen, and cylinder. The technical features and advantages are as follows: What you see in the digital printing process is what you get, as long as a few basic colors, the computer can automatically match the color, and the flower is accurate.

The error is small, and the data storage will never fade. High-quality production, high precision, rich color levels; It cannot be pirated, and the printing accuracy is 180 11440dpi, which can achieve the best effect. The printing process is simple and the production preparation time is short; Fully digital processing, no need to make a network.

Flexible production, suitable for personalized, small batches, effectively reduce inventory. The cost is not related to the output; Proofing and small batch production are economical. Green and environmental protection, use dyes on demand, less pollution, and equipment investment of about 500,000 yuan.

2) The development of digital printing technology The traditional printing uses flat screen and round screen are inseparable from the net, but the cost and time consumed by plate making can not meet the modern printing trend of small batches and multiple varieties no matter what, so the development of no plate, no pressure digital printing. The basic principle is the same as that of inkjet printers. Digital jet printing is a system engineering, involving CAD technology, network communication technology, precision machining technology and fine chemical technology and other cutting-edge technologies, is the product of the integration of information technology and machinery, textile and chemical technology.

At present, a variety of new digital jet printing machines have appeared, mainly using piezoelectric printheads; The maximum stamping speed has increased from LH in 90 years and 6 hours in 2000 to 80 150 hours; The use of dyes was developed from 4 colors to 6-8 colors and 12-16 colors; The application process is becoming more and more mature; The control software function is gradually improved. The development of digital jet printing technology has basically changed from continuous shooting to on-demand jetting, from hot bubble printhead to piezoelectric printhead, and from 4 colors to 6 8 colors. At present, the development of digital printing technology is showing a trend of a group of heroes rising together and a hundred flowers blooming.

3) Application of digital printing technology at present; Digital printing technology can not only be applied to personalization, small batch production and proofing of printing and dyeing enterprises, but also has entered the field of mass production. In Europe, orders within 500 meters are basically taken by digital printing machines, and there are many new printing and dyeing enterprises that only use digital printing systems, which are combined with network design, network production and network sales, and have achieved good economic benefits.

The so-called digital printing, there are two main processes, one is digital sublimation transfer, the other is digital direct injection. Compared with traditional printing and dyeing technology, digital printing has its incomparable advantages, which are mainly reflected in the following aspects:

1. There is no need to make plates, there is no requirement for the number of prints, the output is fast, and the efficiency of the board is greatly improved;

Second, the color is rich and bright.

3. The color of the picture is stable and consistent, and the digital heat transfer is to replace the manual color grading with a computer, and it will never be changed by time or color master, resulting in the difference in the color of different batches of the picture.

Digital sublimation transfer: It is through the digital printing machine to print the design pattern or people, scenery and other documents on professional heat transfer paper, and then through the heat transfer equipment heating, the printed picture is transferred to the corresponding carrier, such as cloth, glass or ceramic products.

Equipment: color inkjet printer, thermal transfer ink, thermal transfer paper, transfer equipment (heat drawing machine).

Digital direct printing: It is through the digital printing machine that the design pattern or people, scenery and other documents are directly printed on the corresponding materials, and then after post-processing (such as sublimation and color fixation, steam desizing, etc.), the process of transfer printing is omitted, but in most cases, in addition to post-processing, the material also needs to be pre-treated, such as sizing.

The two printing processes have their own advantages and disadvantages, relatively speaking, the application of digital heat transfer process is relatively mature, and the current application is more than digital direct injection printing.

Digital printing is an emerging printing method relative to traditional printing, digital printing is generally said to be through inkjet, to achieve active, dispersion, coating, acidic and other printing for different fabrics, flat machine, belt guide machine is one of the digital printing equipment.

Digital printing is done by printing on a specific paper by computer, and then sublimating the patterns previously printed on the paper to the fabric at high temperatures. There is also a kind of digital printing called direct injection digital printing, which is mainly used on cotton and other fabrics.
