I'd be curious to know more about your Rolls Roller, which model do you have, lighted table or not, side rails or not. Obviously you think it is a productive machine but I'd like to know what else you might have to say about it. Do you use it as a general work table too?
We got the entry machine, it maxes out at 54"x8.3', no light table, no side rails. it does do a very good job of mounting vinyl to substrates, and laminating short runs.
I can train someone on it in less than 30 minutes and they will be applying perfect prints all day long. it can be sued as a general work table, but kep in mind the cutting mat is pretty soft, almost a gel so it cuts easily, and at $500 to replace you don't really want to cut through it.
One of the biggest time savers i've found is applying short runs of laminate. we leave our laminator webbed up with 3 mil gloss lam all the time, now if we have a print that needs matte, or dry erase or something, we don't need to unload the laminator, load it back up, get it running straight etc. just cut off what we need and go, no wasting 2-3 feet of laminate loading the laminator, and with some specialty laminates being $25+ per yard, it saves money.
Feel free to ask me anything you like, either here or by PM
