In this paper, a comparative analysis of two approaches to synthesis 2D
 hologram, which restores optical field without conjugated images, is performed. These
 holograms are used in embossed rainbow protective holograms to improve their forgeryproof
 characteristics. As a basis, one method of kinoform hologram synthesis is used,
 which allows to obtain the restored image of acceptable quality, but phase-matching
 condition is necessary to complete. That limits usage of this method in mass production
 of embossed holograms. The offered method of combined holograms is based on
 addition of optical fields restored by separated Fourier holograms. This method let us to
 avoid hard requirements to technical process on resist – polymer relief translating
 accuracy. Thus, the proposed method can be recommended for application in mass
 production of rainbow protective holograms.
