What is the press press?

A print press is a device that uses the pressure to transmit image from some prepared, ink surface on the receiving surface such as paper or fabric. The press printing was one of the great inventions of modern age, allowing bulk books to help spread information. Although its predecessors have existed for some time, the first real press printing was created by Johannes Gutenberg in 1439. It is not possible to afford extremely expensive books handwritten on Pergamen, which could stand like a house or farm, students who were educated and wanted to read themselves. Although at that time there were presses of screws and were widely used in China, a real press press was a new invention that helped reduce the costs and made books available to those who have a little money.

Gutenberg added a number of important contributions to the field of pressing and cast rather than just combine existing technologies. Perhaps the most impressive of them was the type of casting from the alloy of lead, antimony and tin, toThe type could be rapidly thrown from the template, cost reduction and allowing the type uniform to be more uniform. He also came up with a special oil -based ink and replaced water -based inks used in Woodblock, which lasted much longer. Gutenberg printed many books about his press print, the most famous of which was his Gutenberg Bible, of which 48 copies still exist.

In the 18th century, the press press was developed again, with large cast iron presses, replacing the place of earlier presses, allowing to cover larger surfaces while requiring less force. The steam engine was later used to eliminate the need for a human operator who is able to print a mood than 1100 pages per hour. Steam Printing Press has launched an era of mass newspapers, which in turn allowed the masses to be more literate and stay up to date on current events. This was followed by a rolling press, which could print literally millions of pages a day, allowing newspapers to become really massive in their distribution.

up to 30 years 20. WithThe press press has achieved impressive efficiency, allowing cheap, highly volume production, which made the printing of books much more accessible, and therefore allowed more books in a more diverse range of objects. Other progress during the 20th century made books even cleaner and more accessible to the press. For example, Offset Printing Press converts the original print to a soft rubber pad, which then prints on paper and creates a much more readable text. The offset printing remains the main type of printing used for modern book publishing, and although digital techniques are beginning to accept offset printing in terms of costs, their ability to create pure sites of pages has not yet been compared. Some craft books are still pushed by traditional letterpress.
