The persistence and change of letterpress printing

Up to now, letterpress printing still occupies the mainstream position in China's labeling industry in terms of annual installed capacity or market ownership. This is because letterpress printing has all aspects of production cost, process innovation, connection processing and equipment cost. Meet the needs of the Chinese label market. However, letterpress printers cannot sit back and relax. Letterpress is experiencing challenges from other printing technologies, such as those from digital printing, flexographic printing, and offset printing. In recent years, the PS version of offset printing technology is on the rise, and there is a tendency to surpass and replace letterpress printing.

Compared with offset printing, relief printing has obvious advantages in field printing, especially the field printing of film labels because of the higher thickness of the transfer ink layer. For the prevalence of PS printing, the industry generally believes that PS printing meets the "offset complex" of the Chinese people. Offset printing can easily achieve 1% -99% of dot copying, so when printing continuous jobs Compared to letterpress, offset printing has a larger dot range, and the color softness and gradation effect of the printed matter are better. Therefore, offset printing is more popular in the fields of food and wine that require high printing quality.

However, Mr. Zhang Yixiong, general manager of Dongguan Huiyan Machinery Co., Ltd., which has been engaged in the manufacture of letterpress printing machinery for many years, believes that this is just a prejudice. The biggest reason for this quality difference is the difference in plate-making process. Now the CTP platemaking is basically realized in the offset printing field. Only in the label industry, letterpress printing is still using a large amount of traditional film platemaking. Due to the lack of film demand, the quality of the film is reduced, which ultimately affects the quality of the printed products.

As an alternative solution, Dongguan Huiyan Machinery purchased an Esko ESKO DLI digital plate-making system on its own, and set up a plate-making center for this purpose, to provide customers with digital plate-making services far below the market price to help Customers solve various problems encountered in the process of plate making. This plate-making center will also provide customers with information on letterpress printing technology, aiming to enhance the confidence of printing houses in traditional letterpress printing in all aspects.

Dongguan Huiyan Machinery's coping experience is worth learning from peers. However, it is not only the letterpress printing technology that faces the challenges, other printing methods and technologies are also facing challenges. For example, in digital printing, the toner ink technology is being challenged by the inkjet technology; the flexographic printing technology is also facing different Choices, such as ink technology, drying technology, post-processing technology, etc. For equipment manufacturers, it is now necessary to improve the ability of process innovation to meet the changing needs of customers.

In this issue of the magazine, in addition to reports on the experience of using Dongguan ’s ESKO DLI digital plate-making system with Huiyan Machinery, some representative suppliers and printing plants were selected, and through their reports, they tried to dig deeper into successful companies. How to meet the changing market challenges through internal changes.
