The invention generally relates to a raster injector for micropigmentation and use thereof, and more particularly to a raster injector that precisely inserts pigment, medicine or other fluids into skin or other industrial materials. The raster injector is connected to a motion platform that enables the injector to inject pigment or other fluids into the layers of the skin or other substrates through micro, hollow point needles. The raster injector includes a disposable, interchangeable ink delivery assembly, an ink reservoir assembly and a non-disposable base assembly.
