Dot formation positioning device, recording method, setting method, and recording program

A dot formation positioning method for a device including a relative movement unit for bringing about relative movement between a recording medium and a head furnished with a plurality of nozzles to eject fluid from the plurality of nozzles in accordance with raster data with the plurality of nozzles including a plurality of nozzle groups in the direction of the relative movement, and the nozzle groups including a plurality of nozzles in the direction of the relative movement, the dot formation positioning method comprising:

• setting an ejection timing for adjusting, in the direction of the relative movement, the positions of dots formed by each of the nozzle groups;
• adjusting a distribution of adjustment pixels for adjusting, in the direction of the relative movement, the positions of dots formed by each of the nozzles in the nozzle groups;
• and
• ejecting fluid in accordance with both the raster data generated on the basis of the distribution of the adjustment pixels set by the adjusting of the distribution of the adjustment pixels, and the ejection timing set by the setting of the ejection timing.

A non-transitory computer readable medium having a program for a device stored thereon, with the device having a relative movement unit for bringing about relative movement between a recording medium and a head furnished with a plurality of nozzles to eject fluid from the plurality of nozzles in accordance with raster data with the plurality of nozzles including a plurality of nozzle groups in the direction of the relative movement and the nozzle groups including a plurality of nozzles in the direction of the relative movement, the program prompting a computer to carry out:

• a function for setting an ejection timing for adjusting, in the direction of the relative movement, the positions of dots formed by each of the nozzle groups;
• a function for adjusting a distribution of adjustment pixels for adjusting, in the direction of the relative movement, the positions of dots formed by each of the nozzles in the nozzle groups;
• and
• a function for ejecting fluid in accordance with both the raster data generated on the basis of the distribution of the adjustment pixels set by the function for adjusting the distribution of the adjustment pixels and the ejection timing set by the function for setting the election timing.
