Will digital printing on sound-absorbing panels affect the sound absorption effect?

2026-07-16
The impact is very small. High-quality UV inks or water-based penetrating inks, with a coating thickness of only 0.02-0.05mm, will only seal a very small number of micropores on the very surface, and the impact on the overall noise reduction coefficient (NRC) is negligible (usually a reduction of <0.05). However, it is crucial to avoid using paint for spraying, as paint will seal large areas of pores and severely impair the sound absorption function.
