    摘要: Black inverted noises in a white background due to resolution correction are reduced by an image processing apparatus which carries out image modification processing to invert at least a portion of a binary converted signal obtained from binary conversion of an image signal. An image signal S1 is respectively input to resolution correction means 201 and 202 using different correction amounts. The signal is then input to selecting means 310 from the both resolution correction means. The signal output from the selecting means is input to binary conversion means 400 and a signal S2 output therefrom is input to image modification processing means 500. when image modification processing has been instructed, a control signal CNT1 is input to the selecting means 310 and the selecting means output a signal with weak resolution correction from the resolution correction means 202 using a small correction amount.

    摘要: An LDV meter 21 cooperates with an LDV processor 22 to 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 calculator 242 calculates 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 calculator 241 removes 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 machine 1 controls timing for discharge of ink at an ink head based on the belt profile data and the roller profile data.

    摘要: Disclosed is a printing machine comprising: encoders (311 and 312) configured to detect respective angular velocities of a drive roller and a driven roller as a travel speed of core members inside a transfer belt (160); a DSP (321) configured to extract from a temporal variation in a ratio of the measured speed at each roller speed ratio data (profile data) having a frequency corresponding to the speed ratio of a core portion; profile data memory (332) configured to store the profile data; and a head controller (334) configured to control the timing at which each image is formed by a head unit (110) on the basis of the profile data so that positional deviation among multiple images on the transfer belt (160) may be reduced. The head unit (110) forms multiple images on a record medium under the control of the head controller (334). Thus, an ink misalignment at the time of printing can be prevented with high accuracy by recording a change in the core members inside the belt as a profile, using this profile, and reducing memory usage and arithmetic processing load.
