none of the domestic PS rotary label printing machines have passed the technical standard, so they can only be used if the printing quality requirements are not high. If the technology is more mature, it is still Japanese rotary label printing machines, not to say that they are biased towards Japanese rotary offset printing machines, because the domestic PS rotary label printing machines have just been made in recent years, and they are all modified with domestic six-opening small offset printing machines. All the printing factories know the quality of domestic small offset printing machines and can only print some low-demand printed materials. And the failure rate is high. After two or three years, most of them are scrap iron. The PS rotary label printing machine and the relief rotary label printing machine have different requirements for the processing precision of steel and mechanical parts, the assembly technology and technology, and the requirements of assemblers. That is to say, the PS rotary printing machine has high requirements. Today, the PS offset printing machines of Beiren, Dazu Guanhua and Henan new machines in China are not up to standard. The printing quality, machine stability and durability can't be compared with Heidelberg, Roland and Gaobao in Germany, and Komori and Mitsubishi in Japan. Which of these domestic PS offset presses is better than Donghai, Zhongtian, Taihang, Wanjie, Haotian and China Eastern Airlines. They have been unstable for so many years. Can these domestic PS rotary label presses work? Say something you shouldn't say, don't push immature products to the market to cheat money, so you can't be a brand for a hundred years. It's better to buy a Japanese brand relief rotary label printing machine for spending more than two million yuan to buy a domestic PS rotary label offset press. The printing effect of relief CTP plate making is better than that of domestic PS rotary label printing machine, and it has been stable for more than ten years, which is much more cost-effective than buying a domestic PS rotary label offset press. PS rotary printing machine only has advantages for printing paper materials, but has no advantages for printing PVC, PET, PE, dumb silver dragon and other film materials. Now and in the future, printing self-adhesive labels and stickers letterpress will definitely occupy most of the market.
