A new technique for manufacturing 2D/3D embossing holograms, the traversing area partition method, is presented. The basic principle, designing considerations and calculating formulae of the technique are described. In addition, we propose a method using double colour circulation or multiple colour circulation to increase the vertical viewing angle and the striped-speckle screen to increase the horizontal viewing angle. We have used this technique to make a lot of new 2D/3D embossing holograms successfully. Some of the results are shown in this paper.
