Abstract:
A recording apparatus comprising:a recording head having a plurality of discharge ports for discharging inks, said plurality of discharge ports being arranged at a predetermined pitch; scanning means for scanning said recording head in scanning directions; conveying means for conveying a recording medium in a conveying direction; and control means for controlling said conveying means at integer times a minimum conveying unit, wherein said control means controls said conveying means so that ink is discharged onto the recording medium at a pitch of recording dots obtained by dividing the predetermined pitch of said discharge ports by an integer greater than 2, and a conveying quantity of the recording medium corresponding to the minimum conveying unit of said conveying means is larger than the pitch of the recording dots to be formed on the recording medium, wherein a value obtained by dividing the conveying quantity of the recording medium by the recording dot pitch is a rational number, and when a minimum integer that is an integer multiple of the value is divided by an integer obtained by dividing the predetermined pitch of said discharge ports by the recording dot pitch, the remainder is not a divisor, greater than 2, of the integer obtained by dividing the predetermined pitch by the recording dot pitch.
