A translite is a piece if heavy vinyl or clear flexible material that is printed on a printer, with white paint applied to the back. Much like a sign or poster.
The original CC as well as ALL the CCr games come with a translite, A "mirrored backglass" is a really nice upgrade.
A backglass is actual tempered glass with an image silk screened onto it. Pinball machines have had "ink screened", "mirrored" backglasses for decades, it looks really good.
Glass has the ability to allow a mirror treatment to be "heat or chemically" fixed to it, translites being plastic do not. There are NO mirrored translites. However in this modern world there is a mirrored paint that "can" be applied to plastic surfaces.
The term, "mirrored backglass" means an image "ink silk screened" onto glass along with mirror treatment. Although glass can be printed on these days eliminating the screen printing process. Printing is more accurate, but doesnt have the visual depth that silk screening has had in the past. However "Giclee" processes are really close to screened processes.
I REALLY like my mirrored backglass. The colors are corrected to be just EXACTLY right in the LED environment.
IMHO, its just the perfect addition to the LE versions.
