Printing the holographic stereogram (HS) is vulnerable to the vibration when the holographic film is exposed to the continuous wave laser beam compared to the pulsed laser. The continuous wave laser is required to be more longer exposed to the holographic film for forming the fringe pattern, hence the optical system is normally set up on the antivibration system such as optical table which could be a latent defect considering the commercially available printer. This paper covers the design of holographic stereogram printing system which is built upon the non-vibration environment where the ambient noises exist. In order to build a robust system under the common sources of vibration, we designed the optical system which can minimize the effects of ambient noise as well as reduce the optical vibrations. The main source of the noise comes from the stage that transfers the hologram plate hogel by hogel. In order to accelerate the film transportation, we devised and applied an anti-vibration algorithm which can reduce the vibration significantly and the open frame architecture as well. The holographic stereogram printing is conducted using the one-step full parallax stereograms which are generated by setting up the re-centered camera. The optical system features single signal beam converging module to minimize the optical components and tailored optical components. An open frame film stage is integrated into the HS system. For the experiments, the horizontal and full parallax 1mmx1mm, 50x50 and 100x100 hogels are printed to verify the proposed HS printing system.
