Abstract:
1. An image control apparatus for controlling image formation on a print medium by ejecting ink from a print head that includes ejection nozzles through which the ink is ejected while the print head moves in a forward direction and a backward direction, the image control apparatus comprising: a temperature obtaining unit for obtaining information about a temperature of the print head during image formation; a pattern printing control unit for causing the print head to print a first adjustment pattern and a second adjustment pattern, each of which is printed at a first temperature and at a second temperature which is different from the first temperature; and a determination unit for determining a relative timing of an ink ejection in the forward direction to an ink ejection in the backward direction during image formation at a third temperature by interpolating a first relative timing and a second relative timing, each of which are acquired from the first adjustment pattern and the second adjustment pattern printed by the pattern printing control unit.
