What is ImageSetter?
Every press company must get words on paper. Whether newspapers or book publishers often do it with ImageSetter. ImageSetter is a Middleman machine. The text must be converted to a mold that can be used on the print, and ImageSetter performs this role. He is responsible for putting a digital text on a piece of film that can be burn on a print press.
and Priori ImageSetter is a completely separate unit. The operator loads the machine with a film cassette and loads the chemicals and the machine goes to work. It is controlled by a computer that is usually connected to computer with a page. When the table "rolls" negative, the information is sent directly to ImageSetter, which issues a picture on a negative slightly larger than on the page that will be printed. It also goes through the same process. The film is exhibited in the machine, then passes through the developer, stop and a fixer of the bath, as well as the film in the regular camera. The film is then placed on an aluminum or polyester plate and the image is burned into the board. The board goes to print.
On the days before the pictures in front of the images, rates on long metal -type paper were assembled, the type was filled and the picture was photographed on a large camera. The metal type process was replaced by computer printers that made the material in the desired script. Individual articles or stories were then "inserted" on a large sheet of paper the same size as the page and photography on the big camera. Problems with these processes are that every time the copy is created, the subsequent product of lower quality is. ImageSetter solves this problem by putting the text directly on the film.
The computer method on the board (CTP) is a ganking popularity. This method allows printing companies to burn boards directly from the computer with the page. The advantage is, of course, that no quality is lost when changing from computer to film into a record. The next step is eliminated.
Many press companies, especially newspapers, have older presses thatThey are completely mechanical - without computer components. These presses cannot be computer, so the CTP method will not work. However, ImageSetter still provides a high -quality board that can be used for any printing.
TheImageSetter operators must be trained to use their specific machine. It must be able to use a computer with a machine and change film cartridges and chemicals. They may also be obliged to solve problems and maintenance in the pictures.
ImageSetters are usually very expensive machines, but not as expensive as CTP machines. The price depends on the size, manufacturers and functions. ImageSetters Astáals is an important part of the print process.
