Subordinate phase is end of the century early 1990s to 20.Enter the nineties in 20th century, take sheet-fed offset press as mark, printing machinery designing and manufacturing level has striden forward major step in the world.Compared with the type of first stage, the speed of type of new generation further improves, by 10000 seals/hour bring up to, 15000 seals/hour, before printing, the preset adjustment time also shortened to about 15 minutes greatly by about 2 hours of first stage.The gentle production efficiency of Automated water of machine also improves greatly.

Since entering 21 century, printing machinery welcomes the 3rd development phase.At present, some type of sheet-fed offset press can reach 17000-18000 print/hour, but the raising of printer maximum print speed is not done one's utmost to pursue by manufacturer, but by the application of information techenology, further shorten the time that prints front setup time and change living-article and pursue more high efficiency.

Aspect printing machinery automation, networking, produce integrated, Digital Workflow, become the emphasis of exploitation with technology such as linking of management information system (MIS).The CP2000 autonomous cruise speed system of Heidelberg company except to full machine from paper feeding, defeated paper and lead paper, inking, water delivery, plate change, alignment, cleaning, dry, glazing coating, dust and each working link such as collection carries out preset, regulation and control and trouble diagnosing, the function such as image processing data (CIP3/PPF or CIP4/JDF data) before also thering are the whole production process networkings of the printing enterprise of realization, online transmission and printing.Enter the new century, most offset printing press manufacturing firm has all developed corresponding DI digital printer.
