Inking the PIP

Binary ink developer (BID) units apply ink on the PIP. Ink is applied only to the discharged
areas of the PIP. Ink particles are attracted either to the BID developer drum or to the PIP.
The PIP discharged areas, which are the image areas, attract the ink particles. The
charged areas, which are the non-image areas, repel the ink. When the image on the PIP
surface is inked, the image is ready to be transferred to the blanket.
