摘要:
A method of forming an opaque layer includes forming a first layer by discharging droplets of an ink composition containing a metallic pigment on a record medium by an ink-jet recording process and forming a second layer by discharging droplets of an ink composition containing a white pigment on the record medium by an ink-jet recording process. The opaque layer is formed on the record medium on the side where the first layer and the second layer are formed in a region where the first layer and the second layer overlap each other.
