  • Structural characteristics and development of Heidelberg printing machine

    introduction:Currently six major brands(Heidelberg、Manroland、Gao Bao、Komori、Mt. Akiyama、Mitsubishi)Each of the printing presses has its own characteristics,Generally speaking,The printing quality of German equipment is relatively high,The general reflection is that the printing pressure is large、Good stability、Low maintenance rate。There is a certain distance between Japanese equipment and German equipment,But if the operator level is higher,Print quality can also reach a very high level。Similarly if the operator level is low,German machines dont print good products either。For the vast majority of printed goods,There is no significant difference between the two machines。 Heidelberg has a long history in China,Influence comparison
