Inks ○ Verify proper ink flow calibration for all inks using the PrintCare Ink Flow Calibration wizard for each ink. ○ Verify all inks are calibrated for density and conductivity. ○ Rebuild any inks that need to be refreshed (check weekly the BID voltage after performing the color calibration, where available, on a properly defined substrate).

Calibrations and Inspection ○ Keep the press up-to-date on maintenance. ○ Second Transfer Calibration should be checked periodically by wizard or manually (per HP Indigo press type). ○ Perform SPM self calibration (if SPM is installed). ○ Verify all inks are calibrated for density and conductivity. Rebuild any inks that need to be refreshed (check weekly the BID voltage after performing the color calibration). ○ Perform Color Calibration with 3D Color Calibration (3DCC) (if Media Fingerprint has been created); verify they converge successfully. ○ Perform Leading Edge / Trailing Edge Calibration from PrintCare (web presses only).

Substrate
○
Acclimate the substrate to the press environment 24 hr prior to use.
○
Verify the Color Calibration substrate is defined properly (on the press and in the DFE
configuration application).
○
Perform substrate scaling using the
Scaling
wizard and validate using custom quick scaling
grid (web presses only).
Calibrations and Inspection
○
Keep the press up-to-date on maintenance.
○
Second Transfer Calibration should be checked periodically by wizard or manually (per HP
Indigo press type).
○
Perform SPM self calibration (if SPM is installed).
○
Verify all inks are calibrated for density and conductivity. Rebuild any inks that need to be
refreshed (check weekly the BID voltage after performing the color calibration).
○
Perform Color Calibration with 3D Color Calibration (3DCC) (if Media Fingerprint has been
created); verify they converge successfully.
