The playback wavelength shift and the optical property stabilization of the reflection type photopolymer OmniDex film are studied as a function of pressure. As the center wavelength is changed from 632 nm to 482 nm, the bandwidth is 27％ broadened and the diffraction efficiency deviation maintained lower than 10％. These results show that the proposed color tuning method minimizes the change of optical properties more than 50％ compared with the diffusion-based method as the center wavelength changed from 511 nm to 630 nm. The press-based color tuning method shows that it could be used to make holographic optical elements that operate at wavelengths where lasers are not readily available for reflection type holographic recording.
