Offset printer having a press drum larger than its rubber drum

An offset printer comprising:

• (a) a plate making section for reading the image of documents, performing predetermined image processing, and forming images resulting from the image processing on sheet material to produce plates;
• (b) a plate drum disposed beneath said plate making section;
• (c) first means for feeding plates from said plate making section to said plate drum and for wrapping the plates around said plate drum;
• (d) second means for supplying ink and water to the plates while they are wrapped around said plate drum;
• (e) a rubber drum disposed obliquely below and in operative association with said plate drum, said rubber drum having a first diameter;
• (f) a press drum:
• (i) disposed obliquely above and at a predetermined angle relative to said rubber drum;
• (ii) in operative association with said rubber drum at a nipping section;
• (iii) disposed between said rubber drum and said plate making section;
• and
• (iv) having a second diameter that is an integral multiple equal to or greater than two of said first diameter;
• (g) third means for feeding sheets of paper to said nipping section of said press drum;
• and
• (h) fourth means on said press drum for gripping sheets of paper at the nipping section, wrapping them around said press drum, and releasing them at a position located far enough away from said nipping section around the periphery of said press drum such that the trailing edge of each sheet of paper wrapped around said press drum has passed said nipping section before the leading edge is released by the fourth means from the press drum.
