Sorry to hear that you didnt get the results you had hoped for. Im not convinced the process is a total write off though.
Seems there was some milking in the score displays after curing?? This is not present where the ink was applied??
Whatever causes this milking is obviously not IN the glass but on it.

I dont know what inks you are using, or what wavelength UV you use to cure, but i did look into UV inks myself for BG's and got shown UV ink on beer glasses etc - albeit screened though. point is that UV process should not be milking the glass unless there is an unknown medium here somewhere.
In all honesty, id be looking at my glass rather than faults in the process..

Wish you all the best... good luck with WMS!!
