Abstract
A liquid ejecting apparatus includes a liquid ejecting head that ejects a liquid onto a medium, a color measuring unit configured to measure color of a surface of the medium, having a light projecting unit emits a light flux to the surface of the medium and a light receiving unit receiving light obtained by reflecting light emitted from the light projecting unit on the surface of the medium, a changing unit configured to change a reflection position of light, which matches the central axis of the light flux from the light projecting unit, on the medium, and a control unit configured to set the reflection position where color measurement data indicating the highest lightness of the color measurement data pieces of the surface of the medium is obtained as a color measurement position.
