Abstract
By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is decreased by narrowing a nozzle-use range and reducing a conveyance amount over an entire printing region according to a mode used for printing an image in which the coverage of a printing medium is low due to a small number of ink colors to be used, for example, a mode used for printing a monochrome image by using a black ink dominantly in all of the density regions.
