Abstract:
A color measurement apparatus includes a color measurement portion, a carriage, and a movement mechanism the color measurement portion starts color measurement after a predetermined initialization process, a moving section between patches from a point P1 to a point P3 overlaps an initialization section where the spot moves at the time of performing the initialization process, and the moving section between the patches is a section between a forward point having a distance as a radius of the spot with respect to the X direction and a backward point having a distance as a radius of the spot with respect to the X direction, based on a boundary of the patches.
