This one looks like a poor print job from 1997. I am sure that I could do a better job myself on my home ink jet. If I buy a repro part I expect it to be indistinguishable from the original one. I have two NGGs - one with printed translite from 2000 and the other one with original backglass. Seeing the poor repros from licensed sources I have no other option than scanning the original backglass on a Cruse scanner and find a good direct print shop to print an indistinguishable copy. It can be done since NGG has no mirroring print on the backglass. A nice example of Pool sharks backglass resto (although without mirroring):
