Japanese Patent JP2963072

B2

PROBLEM TO BE SOLVED: To enable image data to be recorded with high image grade and almost without density irregularities by providing a means for detecting the relative positional deviation of plural ink jet heads and a means for detecting an angle of inclination with a scan direction of the ink jet heads.
SOLUTION: Each of the nozzle on each of ink jet heads is caused to discharge an ink while moving a head unit for scan relatively with a glass substrate in the X direction to insert an image of line pattern about 50mm long. In addition, a heat pulse of the same pattern is applied to all the heaters of the nozzles and a bit correction is made at an intermediate point (S12). Next, a line sensor camera measures the density of each of the serted images of line pattern while moving for scan relatively with the glass substrate in the Y direction (S13). Further, the ink discharge from each of the nozzles is determined based on the sought density of each of the line patterns (S14). Thus it is possible to obtain data on the irregularities of the ink discharge of each of the nozzles and prevent a color unevenness in a color filter from being generated and avoid the trouble of regulating the relative positions among three ink jet heads.
