Digital printing: The digital printing process

The history of digital printing is still a relatively young one: digital printing processes have only been used for around 80 years. It all began in 1938 when the American physicist Chester F. Carlson developed what is known as electrophotography (xerography). He charged a metal plate coated with sulfur electrostatically. He then exposed it to a lamp. A glass plate with lettering, which was placed between the lamp and metal plate, transferred the lettering to wax paper through the exposure.

Over the decades, digital printing has continued to develop within the framework of new technological possibilities: What initially began as electrophotography, eventually developed into our modern inkjet and laser beam printing processes. In the meantime, digital printing - especially for printed products that are only to be printed in small numbers - has become clear cheaper and more flexible alternative to offset printing established. To this day, a distinction is made between the two most common digital digital printing processes: electrophotographic digital printing and so-called inkjet printing.

  • At the electrophotographic digital printing (electrophotography) the color particles are transferred to the carrier material by means of a photo semiconductor and an intermediate carrier, a so-called dynamic printing form. The principle is based on electrostatic attraction and is also used in laser-based toner printing systems.
  • With the digital Inkjet or inkjet printing the copy of the artwork is not created by means of electrostatic charges, but - the name says it all - with ink. This is transferred to the substrate - usually paper - via a print head equipped with nozzles.

Print shops and copy shops use digital printing. Digital printing is not only possible on paper, but also on textiles, mesh fabric, wallpaper or PVC banners, for example.
