Easy to wash off and retry. Usually we only had a few prototype pieces to play with and we needed to get balanced lighting before going into production. Did a decent job at predicting how the pad printing would work. And was the first step towards molding in the texture on the back side of the lightpipes. We never wanted to have the molds textured until we knew appearance was approved.
I quit doing that work before LEDs were in use. But Z continued until his last design job. It worked with LEDs too.
Fellow Artists! Nice!
Here's a bit of the backstory on the divider. Originally I had pictured a piece of rectangle shaped, solid frosted glass.

The idea was to protect the Media Center from cooktop splatter while also dividing the two spaces of the Galley and Aft Cabin. After I decided to add artwork, I considered making the artwork clear, with the panel mostly still frosted. Then came the idea to do LED's. At that point, it occurred to me there would be too much "frosting" for the lighting. (As you are suggesting.) That's when I decided to reverse it. All that in mind, the highest % of the glass will still be clear. (I'm thinking out loud with all this jibber.) I still want the panel to be a "screen" that divides fore and aft. Also, it will be illuminated less than half the time I suppose. Anyway, once I get some vinyl cut I'll go to the dollar store and buy some picture frames and steal the glass out of them for test carvings. Then I'll know how much is too much, etc.
My Mother is also an Artist, who has found it challenging to understand the Retro-Futuristic, Mid-Century style that I love. I was trying to explain "Googie" to her. Everytime I said "Googie" she was thinking "Google." I kept saying she grew up in the fifties and sixties and should remember that style! Recently, we were in Florida together and passed a little roadside Motel. I said, there it is! That is the Googie style I've been talking about! We pulled in for pictures and she says, now I get it!! Lol! Gotta love it...
