The working principle of the letterpress printing equipment is generally simple. The imitation printing and hand engraving of the prints are the earliest letterpress manufacturing technology in China. This kind of print inheritance has been inherited for nearly a thousand years. The working principle of modern traditional letterpress printing equipment is firstly to ink the ink device and distribute it evenly, and then transfer the ink to the printing plate through the ink transfer roller. The ink on the transfer roller can only be transferred to the graphic with the printing plate, while the non-graphic image has no ink. Nowadays, as the letterpress printing equipment is gradually replaced by offset printing equipment, the market for letterpress printing equipment is extremely sluggish, and letterpress printing equipment is gradually withdrawing from the market. However, parts such as inks, anilox rolls and printing plates have been technologically innovative, and the letterpress printing equipment has been reborn again. In particular, this printing technology also has the functions of simple structure and environmental protection, which once again promotes the re-emergence of this letterpress printing! Now that letterpress printing equipment is no longer a letterpress printing equipment in the traditional concept, flexographic printing equipment has become the main development direction of modern letterpress printing. In terms of printing principle, both flexographic printing and letterpress printing are attributed to the letterpress printing method. However, flexographic printing is a replacement for traditional letterpress printing, and the scale of use is gradually increasing. In today's promotion of printing equipment using flexographic printing, a variety of flexographic printing equipment has emerged on the market, and flexographic printing equipment has been well received by consumers. The development of modern letterpress printing has now moved to the era of flexographic printing. The mission of the traditional letterpress printing equipment is now over, and it is inevitable to withdraw from the printing market. Printing companies should recognize the direction of the company and technology transformation, and eliminate backward production capacity and backward printing equipment as soon as possible.
