Multi channels or FLIP-FLOP
Flip-flop effect is made by 2D/3D master shooting system. It's also called two channel effect of 2D/3D. Flip-Flop hologram can display two images from different viewing angle. When the viewing angle changes horizontally (left to right) or vertically (upside and down), different images evolve through the hologram.
Flip-flop hologram has two or three hologram images or text flips in one position with big different viewing angle. So one hologram image will mask and another hologram image will display when you change the view angle a little bit.
