An object of the present invention is to provide a golf ball having marks which can control the orbit of the head, ballistic trajectory or impact point.
The golf ball according to one aspect of the present invention has a group of multiple marks which are visible at one view. This group of marks includes a target mark consisting of single or multiple marks provided along one great circle. This group of marks includes an inclined mark which appears to be inclined with respect to this target mark.
Preferably, the inclined mark is a linear mark which appears to be inclined with respect to the target mark.

The group of marks includes a target mark consisting of single or multiple marks provided along one great circle. The group of marks includes a side mark provided on the side of this target mark. Preferably, this side mark has a dot shape.
The golf ball according to still another aspect of the present invention has a group of multiple marks which are visible at one view. The group of marks includes a target mark consisting of single or multiple marks provided along one great circle. The group of marks includes an accompanied mark provided on the same great circle on which the target mark is provided.
The orbit of the head, ballistic trajectory or impact point can be controlled by a swing with the address to orientate the target mark while looking at the inclined mark, the side mark or the accompanied mark.
Ink is used to mark or decorate parts. It comes in different chemical families to match the type of material to be printed (please consult the substrate compatibility chart for selection).
