Abstract
There are provided a printing apparatus and an inspection method which can reduce a position deviation of an inspection pattern upon reading the inspection pattern to perform an accurate inspection. A sheet conveyance misalignment in a continuous sheet is corrected in a corrective unit. The inspection pattern is printed on the corrected sheet by a print head of an inkjet type, and the sheet on which the inspection pattern is printed is dried. A sheet conveyance misalignment in the dried sheet is again corrected in the corrective unit, and the inspection pattern of the corrected sheet is read to perform a color shading inspection.
