Printing is the process of transferring an image from a digital file to photosensitive paper. This process can be done in black and white or in color. The image source can be a negative or a positive. In the early years, printing was limited to printed books and pamphlets. Today, printing has been used in textiles, packaging, and in the manufacture of miniature electronic circuits. The technology of printing has evolved greatly since its invention in the 15th century.
Historically, printing has been defined as the application of colour to a surface under pressure to reproduce text or illustrations. However, modern processes are not dependent on mechanical pressure and do not require a material concept for a colouring agent. This represents an important development in printing technology and is likely to replace many other processes in the near future. Today, printing processes are used to reproduce black and white text and illustrations, in colour, or in black and white. And, in the 21st century, it has become the preferred method for reproducing photographs, maps, and other digital images.
When it comes to printing, the process is often divided into stages. One step is the initial creation of the book. The first printing was Diderot’s encyclopaedia, which was the first printed book. From that point on, the process has been instrumental in the accumulation of knowledge. In fact, it was essential to the industrial revolution and scientific and technological revolutions. This process has made possible a wide range of ideas and philosophies, as well as new types of knowledge, such as the Internet.
