Digital printing is a printing technique that allows producing printed materials directly from a PC with no in-between steps. Digital printing differs from other printing techniques by the absence of tangible and permanent printing form, or a plate, and thus it is used in reprints or additional issues, or variable texts in small-run editions. One of the options in digital printing is inkjet printing based on the principle of propelling the coloured inks in the form of tiny droplets at very high velocities directly onto the printed substrate. The ink subsequently permeates the material and thus takes on a partial security function as well.

Other types of digital printing techniques are laser prints with toners (powdered inks) such as magnetography or xerography (electrophotography).

At SPWS we use digital printing techniques especially in additional prints of variable data (numbering, additional printing of barcodes and QR codes) onto paper or in personalising plastic cards.
