Hoshovsky Web Offset Lithography Facts

            Most of the information that I am finding is new to me, as well as interesting. While doing the research here are some of the facts that sticks out, as well as information that I found intriguing:

•  Mass-production printing in which the images on metal plates are transferred (offset) to rubber blankets or rollers and then to the print media. The print media, usually paper, does not come into direct contact with the metal plates.
• The main advantage of offset printing is its high and consistent image quality. The process can be used for small, medium or high-volume jobs.
• In the early twentieth century, the accidental discovery that a rubber blanket transferred images to paper more efficiently and with greater quality than lithographic stones (the "offset" in offset lithography) gave the printing process the impetus it needed for wide commercial acceptance.
• "Web-offset" presses are fed from a large roll of paper, which goes through the press in a continuous length of paper, called a "web." Sheet-fed presses are generally used for business marketing printing, while web presses are more cost-effective for high volume printing of catalogs, newspaper inserts and magazines (around 50,000 quantity or more depending on the size and type of piece).
• Web and sheet-fed offset presses are similar in that many of them can also print on both sides of the paper in one pass, making it easier and faster to print duplex.
