Evolution of cheap and powerful microcomputers, development of comprehensive word processing and page planning software and availability of near letter quality laser printer with ability to mix various front styles and graphics, have made concept of DeskTop Publishing a reality.
Over the last few years, computers have penetrated every respect of industry, business and education. They have totally changed the way in which information is processed. Now with the advantage of desktop publishing (DTP), the method of presenting information has also changed.
Today man has a tool, which allows him to design, layout and produce printed matter right at his disk. One can create newsletters, reports, data sheets, and broachers in a matter of minutes on a computer screen, and print it out on a laser printer in seconds.
Like any other computer system the three main components of DTP are hardware, software and printer.The system is equally comfortable with text or graphics. The both can be mixed at the same time.
To sum up, desk top publishing has come to stay. But its full potential and applications by only be realized by those conversant with the various packages available.
Laser Printers and Digitizers
Desktop publishing involves many components, but without good output devices, all the effort that goes into designing and laying out pages is wasted. Currently, the primary high-resolution output device in a desk top publishing operation is the Laser printer. Most good looking documents that result from desktop publishing are nicely formatted type.Laser Printers and digitizers as much as computers and software-makes desktop publishing a personal rather than a strictly corporate or industrial endeavour.
Laser Printers
A laser printer is a photocopier. In fact, many such printers use the same technology that photocopiers do, a photosensitive drum temporarily holds an electric charge in the shape of an image transferred to it by a computer-driven laser beam. The charges and the image carried within it are transferred to a sheet of paper as it rolls across the drum. The paper then attracts the toner (plastic ground into a fine powder) and heat bonds the toner
of the paper.
Digitizer; Producing Graphic Images
A digitizer transforms an image into digital information you can store in a computers memory or on a mass storage device. You can then transfers that information to a bit-mapped screen, whereas you can edit it repeatedly, or to a high resolution output device such as a laser printer. Digitizers are of two sorts: Video and Optical.
