I’m currently evaluating options for creating a masking sheet that will go in front of some LEDs to create letter outlines. I wish to create something that has an opaque “background” but translucent white letters that will allow light to shine through.
I notice you guys stock a “black top white core” acrylic. I’m wondering if I could achieve my goal by having a sheet of that material laser-engraved so that the black top is removed and the white core is revealed below, and thus have the light shine through the engraved areas. I’d then place the material black-side-up, showing the white engraved letters on a black background.
Does that seem plausible or is there some constraint I’m not seeing that makes this a bad idea?
Also, given that I wish to engrave solid letters rather than outlines, am I correct to assume that raster engraving is what I need here?
Thanks in advance for your help!
