Abstract
An LDV metercooperates with an LDV processorto measure travel distances or travel speeds of a transfer belt at a prescribed measuring spot and at intervals with a prescribed rotation angle of one of a set of rollers, on which the transfer belt is stretched, as a set for one or more go-around revolutions of the transfer belt. A roller profile calculatorcalculates a roller profile data as a set of fractions attributable to an eccentricity of the set of rollers in a set of measurement data. A belt profile calculatorremoves the set of fractions attributable to the eccentricity from the set of measurement data and calculates a belt profile data representative of irregularities in thickness of the transfer belt based on the set of measurement data after removal of the set of fractions attributable to the eccentricity. In printing, a printing machinecontrols timing for discharge of ink at an ink head based on the belt profile data and the roller profile data.
