In 1904, Kaspar Herrmann in Germany was trying to improve the lithographic technique by trying out countless experiments to find out a new mode of production. The American, Mr. Ira Washington R. Rubé, intervened in this research by accident. During a printing job, Ella Washington Rube noticed that there was a sheet of paper that did not travel as usual during the printing process. He tried to print a pattern on both the front and the back of the sheet and the image was first passed from the plate Impression roller blanket, and then printed on paper. Unexpected scenarios arose: This indirect imprinting method produced products of higher print quality, with a flexible blanket surface that delivered the ink more evenly to the paper. The printing method developed by Kasper Herrmann and Ella Washington Rubé was born, and that is what we often say about offset printing. They each designed a sheet-fed offset printing press but did not commercialize it immediately. Until 1912, Universal launched the world's first rotary offset printing press at a speed of 8,000 sheets / hour, and the offset press truly recognized the world.
