Assembly line design

The basic idea of this pattern is much like the idea of an assembly line: To perform a sequence of essentially identical calculations, each of which can be broken down into the same sequence of steps, we set up a "pipeline", one stage for each step, with all stages potentially executing concurrently.

Printing technology traveled quickly across Europe and, at a time of great religious change, played a key role in the success of the Protestant Reformation.

Gutenberg produced copies of his Bible. The printing press drastically cut the cost of producing books and other printed materials. The materials involved were also costly: Monks wrote on treated skins, known as vellum.

Printing onto paper made copying cheaper and faster. The first books Gutenberg printed with his press were copies of the Bible. The Gutenberg Bibles were immensely popular, and all copies were sold even before the copying was complete.

The newly printed version Gutenberg created became the standard version and the basis for most future Bible texts. As such, the printing press played a key role in popularizing ideas associated with the new Protestant faith during the European Reformation, allowing the press to shape and channel a mass movement.

In the very early years of the Reformation, German-language printing presses produced hundreds of pamphlets by Reformation leader Martin Luther, outnumbering Catholic writers five to three and making up 20 percent of all pamphlets published between and The invention of the printing press removed control of written material from the Catholic Church and made it difficult for the church to inhibit the spread of what it regarded as heretical ideas.

The printing press has had enormous implications for education and the state of the world. Ideas from the Italian Renaissance spread west and north, and influenced artists, scientists and philosophers throughout Europe and beyond. The Gutenberg Bible Before the invention of the printing press, ideas and experiences often died with the person who possessed, so each generation had to start from scratch.

Background

The invention of the printing press meant scholars could read work done by other scholars and build on this knowledge. Scholars could communicate their ideas with other people working on similar ideas who lived in different areas.

The printing press vastly reduced the amount of human labor involved in making books, so the price of books came down considerably. Hence, people could buy books who were never able to buy them before. Libraries were established and commoners became more educated than ever before.

Printing press, machine by which text and images are transferred to paper or other media by means of ink. Although movable type, as well as paper, first appeared in China, it was in Europe that printing first became mechanized.

The earliest mention of a printing press is in a lawsuit in Strasbourg in revealing construction of a press for Johannes Gutenberg and his associates. The invention of the printing press itself obviously owed much to the medieval paper press, in turn modeled after the ancient wine-and-olive press of the Mediterranean area.

A long handle was used to turn a heavy wooden screw, exerting downward pressure against the paper, which was laid over the type mounted on a wooden platen. In its essentials, the wooden press reigned supreme for more than years, with a hardly varying rate of sheets per hour printed on one side.

Metal presses began to appear late in the 18th century, at about which time the advantages of the cylinder were first perceived and the application of steam power was considered.

By the midth century, Richard M. Hoe of New York had perfected a power-driven cylinder press in which a large central cylinder carrying the type successively printed on the paper of four impression cylinders, producing 8, sheets an hour in 2, revolutions.

The rotary press came to dominate the high-speed newspaper field, but the flatbed press, having a flat bed to hold the type and either a reciprocating platen or a cylinder to hold the paper, continued to be used for job printing.

Houston Chronicle newspapers being printed on a rotary press, A significant innovation of the late 19th century was the offset press, in which the printing blanket cylinder runs continuously in one direction while paper is impressed against it by an impression cylinder.

Offset printing is especially valuable for colour printing, because an offset press can print multiple colours in one run.

Offset lithography—used for books, newspapers, magazines, business forms, and direct mail—continued to be the most widely used printing method at the start of the 21st century, though it was challenged by ink-jet, laser, and other printing methods.

Apart from the introduction of electric power, advances in press design between and the s consisted of a great number of relatively minor mechanical modifications designed to improve the speed of the operation. Among these changes were better paper feed, improvements in plates and paper, automatic paper reels, and photoelectric control of colour register.

The introduction of computers in the s revolutionized printing composition, with more and more steps in the print process being replaced by digital data.

At the end of the 20th century, a new electronic printing method, print-on-demand, began to compete with offset printing, though it—and printing generally—came under increasing pressure in developed countries as publishers, newspapers, and others turned to online means of distributing what they had previously printed on paper.BADM Assembly Line Design Problems (Solutions) Assembly Line Design Problems (Solutions) The following tables give the tasks, task times, and predecessors that are to be performed on an assembly line.
