Description
technical field [0001] The invention relates to the technical field of offset printing machines, more specifically, it relates to a high-stability five-color offset printing machine. Background technique [0002] The offset printing machine is a kind of lithographic printing machine. When printing, the printed image and text are first printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. Offset printing machines can be divided into sheet-fed offset printing machines and web offset printing machines according to different feeding methods; according to the number of printing colors completed in one pass, they can be divided into single-color, two-color, four-color and multi-color printing machines; The largest paper format can be divided into small offset printing machines, six-fold, four-fold, folio and full-sheet printing machines, and there is also a double-sided printing machine that can print on both sides at the...
