Difference between thermal transfer printing and screen printing in the book printing progress
Many factory know the existence of thermal transfer printing and screen printing, but do not know what is the difference between them in the book printing progress.
In China printing service, thermal transfer printing process and screen printing process are common special printing technologies. What are the differences between the two processes? Let's introduce the knowledge of thermal transfer printing and screen printing.
The principle of thermal transfer printing is to first use the photographic plate making method to make the steel plate into gravure, and then transfer it on the printed object through a special silicone printing head. Special ink can be prepared according to the material of the product, so as to ensure the quality. The principle of screen printing is to make holes that can pass through the ink on the plate base of the printing plate (paper film plate or other plates).
During book printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the holes of the hole plate through a certain pressure to form an image or text. thermal transfer printing technology has many similarities with screen printing technology. For example, it has wide adaptability to substrate; There are many kinds of ink, thermal transfer printing ink and screen printing ink can be used generally; It is very convenient to complete the printing of different products by changing the fixture and printing plate.
Therefore, on many occasions, thermal transfer printing technology and screen printing technology are inseparable and play an important role in special printing. It is precisely because thermal transfer printing technology and screen printing technology are so close that most book printing experts classify it as the field of screen printing. So far, there is no special organization to study thermal transfer printing technology, There is also a lack of institutions to conduct detailed investigation on the distribution of pad printing technology in the market. Many data involving pad printing enterprises can not independently reflect the actual situation of pad printing technology.
However, there are many differences between thermal transfer printing and screen printing, such as: there are obvious differences in the transfer process of ink; The structure of printing press is different; The types of substrates are also very different. In fact, the differences between them are much greater than the similarities. We are used to binding them together because they face a common market. In this common market, thermal transfer printing is inseparable from screen printing, and screen printing is inseparable from thermal transfer printing. Stripping thermal transfer printing from the screen printing industry is difficult and unnecessary, but if you want to deeply understand the current situation of thermal transfer printing technology, you can't look at it from the perspective of the screen printing industry. We attribute all printing involving paper to mainstream printing. Mainstream printing has always been highly valued by the theoretical circle.
In recent years, screen printing has been valued. The primary reason is that its printing advantages in paper have been found, rather than people's attention to its advantages in the range of substrate, such as using screen printing to complete UV local glazing of paper, Special UV inks such as coral ink, ice flower ink and wrinkle ink have better effect than printing and flexographic printing. Thermal transfer printing technology is not so lucky.
Today, when all printing processes are exploring to give full play to their respective advantages and move towards integration, thermal transfer printing technology still maintains its independent identity, and the connection between paper and thermal transfer printing technology is still blank, but thermal transfer printing technology does not stop its rapid growth, because the field in which pad printing technology is good can not be completed by any other printing process, The prosperous industry in the Pearl River Delta strongly supports the high growth rate of thermal transfer printing industry of 18% per year. The employment opportunities created by pad printing technology related industries every year have also been concerned by * 11 * departments.
Generally speaking, the technical content of thermal transfer book printing process is not high, and it is very difficult to continue to develop under the situation of high production costs in developed countries. Therefore, it is an inevitable trend for pad printing industry to transfer to developing countries with low labor costs such as China. At present, in addition to a few foreign enterprises manufacturing highly automated pad printing production lines. Most enterprises have moved their production bases to China and produced cheap book printing China, which is a historical opportunity for China. Contact us freely for the best China printing service.
