Today I went to the silk screen shop & the shop manager said they won't do 4 color process to glass using the flat bed incase the 50k print head gets destroyed. They will do a high dot print to film & install. I will post the results when the 1 glass gets done.
My printer just got a new Epson 1200 dpi printer & a plotter cut to go next to it. I don't know the commercial model, since i just got a brief look. We will probably try the same art file & compare results. The process will be to apply films dry. The plotter can cut the windows for displays in all films.
