In fact, Heidelberg in Germany, Komori in Japan, Akiyama, Gauss International and Roland are all of the same grade, but in the domestic market, at least Heidelberg in Germany is the most widely used brand at present, but the best does not mean the most suitable. If you want to buy it, you must consider many questions, such as: What are the main types of prints? What is its maximum width? How accurate do you need to be? How many colors do you need? (Generally four or six colors are used), is it necessary to add light? (The purpose of glazing is to make printed matter appear smoother and brighter) ... Wait until you have the answers to these questions in your heart, and then talk to the seller in another way!

Hmm ... By the way, tell you a few printing press manufacturers in Shanghai. You can actually get to know: Heidelberg printing press is in Qingpu, Shanghai, and Akiyama is in Baoshan District (Shanghai Guanghua Printing Machinery Co., Ltd.) and Gauss China.

There may be something wrong with my answer, for reference only!
