Digital printing is based on technology that prints directly from the data of a digital file using electrophotographic imaging.
Typical areas where digital printing is used today are food, pharmaceutical, industrial chemical and special product labelling, multi-language print jobs and personalisation.
The main driving forces for digital printing are:
- profitable short to medium print runs
- no films, no plates
- fast turnaround
- high-quality prints
- no waste
- a wide range of substrates to print on
HP Indigo and Xeikon - the main press manufacturers
HP Indigo and Xeikon are the main digital printing press manufacturers in the world today. Both companies were founded in the late 1980s and introduced their first digital colour printing machines in 1993.
HP Indigo uses digital offset technology with liquid toners called ElectroInks. This technology sets high requirements on the printing substrate if good ink anchorage is to be achieved. UPM Raflatac's HP Indigo products have a special topcoat to ensure good print quality.
Xeikon technology is based on LED electrophotography. This technique requires that the printing substrate has optimal and uniform resistivity, which can only be achieved through correct and uniform moisture content and good material formation.
