The clarity, image stability and continuity, and color authenticity of water screen movies are all determined by the quality of the water screen generator and water screen. Water curtain films have the following basic requirements for water curtain quality:

1. The water curtain generated by the water curtain generator is fan-shaped and consists of a dense water curtain area and a discrete water curtain area. Film and television images are projected onto a dense water curtain area for imaging, so their radius must be greater than the size of the image.

2. The dense water curtain area must be composed of uniformly sized micro water droplets with a diameter of 0.5mm, and the distribution of water droplets must be tight and without gaps.

3. The thickness of the water curtain is one of the important indicators of its stability, and it should not be too thick or too thin. If it is too thick, it may cause twice imaging, leading to blurring and distortion of the image; Being too thin can easily be swayed by wind or the water curtain shatters, affecting the quality of the image.

4. The water curtain should be adjacent to the water surface and perpendicular to the water surface, making the image appear to be moving on the ground or water surface, with a strong sense of three-dimensional and closer to life.

5. When making water curtains on natural water bodies (such as reservoirs, lakes, and rivers), the water curtain generator should be able to rise and fall with the rise and fall of the water level.
