The wavefront printer is an equipment to produce computer-generated holograms (CGH) as a volume hologram. This printer records the wavefront generated by spatial light modulator (SLM). We propose a novel technique for applying phase-only SLM to the wavefront printer without losing the advantage of the wide space-band product of phase modulation. The phase-only SLM commonly has the problem of degradation of generated wavefronts because of coding noise due to phase only modulation. To reduce the noise, a technique is presented in order to partially modulate amplitude of recording light in phase-only SLM.
