The first stage of printing press development

The first stage was from the early 1980s to the early 1990s. This stage was the heyday of the development of offset printing technology. The maximum printing speed of sheet-fed offset press during this period was 10,000 prints/hour. The pre-adjustment preparation time for a four-color printing machine before printing is generally about 2 hours. The automatic control of the printing press mainly focuses on the aspects of automatic paper-bearing, automatic paper delivery, automatic cleaning, automatic detection of ink color, automatic adjustment of ink volume, and remote control of register. In addition to single-color and two-color presses during this period, almost every single-fed offset press manufacturer also had the manufacturing capacity of four-color presses, and most manufacturers were able to manufacture paper turning mechanisms for double-sided printing.
