Well you might want to
Well you might want to reverse engineer it – get all the information about her system and look it up to find out if it will work with glass. The reason I’m suggesting this is because I just found a boat load of “industrial printing equipment” but I don’t have a clue if it’s what she has. All of these systems will print color decals for glass and ceramics
I could go on and on but there’s a boat load of equipment that will do the job – what does she have then look up the equipment and see if it will print glass decals. This is just an idea – most printing companies aren’t going to put the type/brand etc of equipment they use commerically. For the most part who cares, we care more about what we can use in the home – laser jet etc.
Good luck – I’m sure you figured it would be much easier than this – LOL.
