100 Chapter 8 Handling ink
ENWW
Overview
HP ElectroInk, the ink used on the press, is mixed on the press from three components:
imaging oil, imaging agent, and ink concentrate. Ensure a constant supply of both the
imaging oil and the ink concentrate. The press system automatically identifies shortages
of either of the two components, and prompts you to take the correct course of action.
To ensure consistent printing quality and smooth press operation, the press monitors the
following ink characteristics:
z
density (concentration of pigment particles in the ink)
z
conductivity (the adherence capacity of ink to the image areas and its repulsion from
non-image areas)
z
temperature (determines adherence of ink capacity to the substrate)
z
ink tank levels
When the ink characteristics approach the specification limit, the press system displays a
warning message. If you ignore the warning, and the ink characteristics slip outside the
limits, the press changes to the Standby
state.
The press ink system is a semi-closed system. The press system creates ink in the ink
tank using imaging oil and ink concentrate supplied automatically by the press system. Ink
is charged by an automatic addition of imaging agent and is heated to 30° C (86° F). The
pump stirs the mixture and drives it through the pipes. The press system pumps each ink
to its respective BID where it adheres to the PIP.
