A printing apparatus includes an ink application unit, a reactant application unit, a control unit configured to control an application amount of the reactant to be applied by the reactant application unit, and an identification unit configured to identify a pixel included in a line portion based on image data indicating an image to be formed on the print medium. The control unit controls the application amount of the reactant so that an amount per unit area of the reactant to be applied to a region in which the line portion to be formed on the print medium with the pixel identified by the identification unit is to be printed is less than the amount per unit area of the reactant to be applied to a region in which an image including a pixel not identified by the identification unit is formed.

An image processing apparatus performs predetermined image processing for read data obtained by reading an image on a document by first and second reading sensors arranged so as to have an overlapping area. The predetermined image processing includes color correction processing of converting color signals detected by light receiving elements of the reading sensors into color signals with respect to each of pixels forming read data. Color correction processing for first read data obtained from light receiving elements of the first reading sensor not included in the overlapping area and color correction processing for second read data obtained from light receiving elements of the second reading sensor not included in the overlapping area are performed in accordance with different correction characteristics. By doing this, an image in which image unevenness caused by individual differences of the short reading sensors is reduced can be output.

A width in a first direction of a line in image data corresponding to an image to be printed by a printing apparatus is corrected, based on information on a print result of line-width detection images printed based on line-width detection image data in a raster format that is generated by performing rasterization processing on line-width detection image data in a vector format. In the line-width detection image data in the vector format, a distance between centers of the widths in the first direction of two lines adjacent in the first direction in each line-width detection image is an integral multiple of a rasterization resolution in the rasterization processing.
