The best competition between ink jet printing and

  • Detail

Ink jet printing is a non-contact, non pressure, non printing plate printing reproduction technology. It has the common features of no plate digital printing and can realize variable information printing

the printing plate of screenprinting is in shape. During printing, the ink on the printing plate leaks from the through hole of the plate to the substrate under the extrusion of the ink scraper, and then the printing operation is completed

I. Introduction to two printing methods

1 Inkjet printing

(1) the principle of inkjet printing there are many inkjet printing methods, the basic principle of which is to input the graphic information stored in the electronic computer into the inkjet printer first, and then through a special device, under the control of the electronic computer, spray mist like ink droplets from the nozzle to the surface of the substrate, According to the charge effect, the company will send professional maintenance engineers to the site within 24 hours for maintenance services to directly image the substrate surface and become the final printed matter

(2) classification of ink-jet printing with low quality and simple repetitive work

① classification according to ink-jet system

the basic principle of ink-jet printing is to produce small ink drops first, and then guide them to the set position. According to different inkjet systems, it can be divided into continuous and on-demand

continuous ink-jet printing (CIJ), regardless of the image type or non image type, continuously generates ink drops in a flow manner, and then forms an image through electric field deflection and transfer, and finally recovers or disperses the non image ink drops

on demand inkjet printing (DoD) produces ink droplets only in the image area. It is specially used for printing images of excellent quality. It is suitable for printing packaging color pictures, textiles and large format billboards. It is an ideal choice for full-color and high-precision printing. Printing quality is its most important consideration

② classification by printing color

inkjet printing can be divided into black-and-white inkjet printing and color inkjet printing according to its printing color. Black and white ink-jet printing uses a single ink, the machine structure and ink system are relatively simple, while color ink-jet printing is relatively complex

2. Silk printing

(1) the principle of silk printing

modern silk printing technology is to use photosensitive materials to make a silk screen printing plate by photographing (making the silk holes in the picture and text part of the silk screen printing plate as through holes, rather than the silk holes in the picture and text part blocked). During printing, the ink is transferred to the substrate through the hole of the image and text part through the extrusion of the scraper to form the same image and text as the original

(2) composition and equipment characteristics of silk printing

silk printing consists of five elements, namely, silk printing plate, scraping scraper, ink, printing table and substrate. The silk printing equipment is simple, easy to operate, easy to print and plate making, low cost and strong adaptability. Silk printing has a wide range of applications. There are also many common printing materials, such as color oil paintings, posters, business cards, binding covers, commodity signs, printing and dyeing textiles, etc

II. Comparative analysis of two printing methods

inkjet printing is another 10000 printing refresh technology after silk printing. Like silk printing, it has a wide range of printing materials, and can be printed on the surface of different shapes and materials. It has strong adaptability. At present, it is a new printing method with extremely rapid technological development and expanding market, showing great development prospects. However, as an old-fashioned printing method, silk printing also shows a healthy side in the development process, especially the unique advantages of silk printing in circuit board printing. In addition, with the application of more and more new technologies in silk printing, the old appearance of silk printing has been changed, and it still occupies a large market

1. Competition between the two printing methods

(1) competition in application field and product market

based on the advantages of the two printing methods, it is not difficult to find that the competition in the printing market that they cannot be mixed with other materials is becoming increasingly fierce. First of all, some large format printing fields compiled by silk printing are being impacted by inkjet printing. Nowadays, the inkjet machine used in the large format inkjet field has a maximum format of 3 ~ 5m, and plays an increasingly prominent role in the production of large format posters, publicity materials and outdoor advertisements. Secondly, because ink-jet printing has relatively small restrictions on the substrate, it can be printed on a variety of substrate materials, which is the killer mace of silk printing compared with other printing methods. With this advantage, ink-jet printing will undoubtedly have an impact on the application field of silk printing. Thirdly, inkjet printing belongs to full digital printing, which completely breaks away from the cumbersome process of traditional printing process, and can minimize the time to market. For those products with high time requirements, this printing method will be the best choice

(2) competition with printers

inkjet printing has its own unique market, such as lottery printing and personalized printing, which is beyond the reach of silk printing. While defending these fields, inkjet printing has extended its application to the territory of silk printing, and its products are gradually favored by a wide range of printers. As mentioned above, in large format printing, with the prosperity of market economy and the expansion of commodity circulation, the ink-jet printing of outdoor advertising will show a sharp upward trend. The advantages of ink-jet printing, such as full digitalization, personalized printing and remote printing, will inevitably attract more printers to adopt it. Therefore, it can be said that while competing in the product market, their competition is also inseparable from the competition with printers two years later

2. Complementary advantages between the two printing methods

combining the two printing methods can save production time and improve efficiency. Although ink-jet printing has the advantages of full digitalization, short operation preparation time and quick response to the market, it is not perfect after all. One big drawback of ink-jet printing is that it is not suitable for mass printing, but only for printing less than 1000 pieces. Therefore, the technical advantages of silk screen printing brush in mass printing are fully revealed. This method can be adopted when determining the personalized printing of product packaging, that is, inkjet printing is used for small batch printing first, and then research is carried out after it is put into the market. According to the research results, popular designs are selected for large batch printing, which not only saves costs, but also reduces waste and product time to market. The collocation described above is only an option. Of course, there are other better ways to use it
