Inking calibration problems: causes and fixes
6 Inking calibration problems in offset printing and finishing: symptoms, probable causes, step-by-step fixes and prevention.
Inking calibration · TPG-092
Full ink train calibration (procedure)
Uneven inking, constant key corrections, unstable color
Inking calibration · TPG-093
Form rollers badly set to plate
High gain, plate wear, heavy or starved inking
Inking calibration · TPG-095
Fountain keys out of zero (false profile)
Console/CIP3 preset doesn't match output; long make-readies
Inking calibration · TPG-097
Wrong plate-blanket / blanket-paper pressure
Overall high gain or weak image; premature wear
Inking calibration · TPG-094
Ductor and vibrator out of sync
Irregular ink band; color pulses at the ductor rhythm
Inking calibration · TPG-096
Oscillator distribution badly set
Persistent ghosting, lateral bands, mixing across key zones
