Digital printing is the reproductionof an image or images by translating digital code direct from a computer to a material without an immediate physical process.
Usually referrs to small print runs which are printed using large formats. Digital printing has a higher cost per page rather than traditional offset printing but usually saves costs by cutting out all the steps inbetween.
The main difference between digital and traditional is that digital requires no printing plates which in turn saves time and money.
The most popular methods include inkjet or laser printers that deposit pigment or toner onto a wide variety of substrates including paper, photo paper, canvas, glass, metal, marble and others.
In many of the processes the ink or toner does not permeate the substrate, as does conventional ink, but forms a thin layer on the surface and may in some systems be additionally adhered to the substrate by using a fuser fluid with heat process (toner) or UV curing process (ink).
