We have performed some initial tests with various patterns for up to 2 hours with only minimal warpage of the film. Individual experiences may vary depending on the density of the pattern. We have seen a heavy black printed film warp and begin to smoke. We suggest keeping the printing under 50% of the area and orient the printed side away from the LED source.
