rrrrraaaooowww.  Not sure if you meant it, but that comes across incredibly arrogant.  I don't see anywhere we he comes across as trying to sound like he came up with the idea.  He simply responded to a question with some updated information for those on the fence about buying one of these backglasses.  John Greatwich does it, Pinball Rescue did it when they were doing backglasses, I'm sure many others do it too. 

Never said that he came up with the idea.. I did suggest that he " flowered" up his language to make it sound more technical than it is.
Arrogant??? If that's how it comes across then that's how it is I guess.. like I said its not rocket science and anyone in the sign trade would have been able to tell him that you HAVE to double strike the ink.
Arrogance is when someone starts to print off backglasses to sell but doesn't know exactly how to do it... read the posts - these were being sold already when the guy didn't know what he was doing.
