摘要： In a recording apparatus provided with a plurality of discharging ports for discharging ink, and discharging elements for discharging ink upon application of electrical pulses, the volume of ink droplets discharged from each of the discharging ports is caused to vary due to the properties of each discharging port. This variation results in a conspicuous unevenness in recording. The present invention provides a method for making such recording unevenness due to the properties of each discharging port inconspicuous by varying the volume of ink droplets discharged from each of the plural discharging ports at random. Also, the present invention provides a technique in which the volume of discharging ink droplets is varied at random by use of a specific ink in order to make the recording unevenness inconspicuous.

摘要： An adverse effect of air flows occurring near the nozzle line with high print duty is reliably avoided by appropriately dividing and allocating the print data to a plurality of ink ejection nozzle lines. When the print head is scanning in a forward direction, a combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used. When the print head is scanning in a backward direction, another combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used.
