The history of the printing press
The invention and development of the printing press has played a significant role in the dissemination of human civilization and culture. In 1439, Gutenberg of Germany made a wooden relief printing press. This vertical, screw-type hand-operated printing press, though simple in structure, remained in use for 300 years; in 1812, Koenig of Germany produced the first flat-bed rotary printing press; in 1847, Hoe of the United States invented the rotary printing press; in 1900, a six-color rotary printing press was produced; and in 1904, Rubel of the United States invented the offset printing press.

What is the control principle of an intaglio printing press?
The tension zones of an intaglio printing press can be divided into three areas: unwinding tension zone, printing tension zone, and slitting tension zone. The unwinding tension zone includes the tension control from the paper core to the feed tension roller in the guide group; the printing tension zone includes the tension control from the feed tension roller in the guide group to the delivery tension roller in the printing group; the slitting tension zone is from the delivery roller in the printing group to the slitting tension roller. For intaglio printing presses without a slitting group but only a rewinding group, the slitting tension zone includes the area from the paper tension roller to the rewinding shaft.
