Quality STANDARD for Non CLR/ALR – RETRACTABLE PROJECTION SCREEN

1. Turn off the lights and project an image.
2. View the screen at the diagonal distance (Example: 125”/150” diagonal screen ≈ 10ft/13ft)
3. No visible waves or lines
4. QC standards/evaluations are NOT performed with the lights on, as ambient light can create reflections, shadows, and perceived surface waves that distort the screen’s appearance.

Below are examples showing the SAME projection screen but different results when the lights are on and off.
