A drawing apparatus detects, as base coat information, a contour of a base coat region which is formed on a surface of a drawing object by applying a first ink used for a base coat on the surface of the drawing object with a drawing tool so as to fill in a design region surrounded with a contour of a design image, before the design image is printed on the surface of the drawing object, and adjusts a size of the design image and generates an adjusted design image which has a size sufficient to cover a whole area of the base coat region, based on the detected base coat information.The drawing apparatus then prints, by a print head, the adjusted design image on the base coat region at a position at which the adjusted design image covers the whole area of the base coat region.
