2.2 Offset Press vs. Digital imagePRESS
Offset printing
is a technique that transfers (or “offsets”) an inked image from a
plate to a rubber blanket, and then to the printing surface. This enables the offset
press to maintain a consistent and high image quality over long print runs because
the plate never touches the paper. The process requires a substantial investment in
equipment and setup time to achieve these results.
A
digital press
uses an electrostatic process to produce “offset-like” image quality
at a fraction of the cost of an offset press. In the imagePRESS V1000 digital press,
the drum is imaged; the toner is applied, and then transferred to the ITB
(Intermediate Transfer Belt). The ITB then transfers all four toner colors to the paper
in one single pass. The small toner particle size captures a greater color gamut
space, closer to that of an offset press.
