I dont know if this is in the right section or not, but trying to get a quick answer on this before we order more product. Normally we us 180CV3 with our Roland VP-540, but our supplier has a special on the 170cv3 which I am unfamiliar with. On 3M's website the only difference I could find is on the 170 it says "for piezo inkjet only" and 180 says "solvent/uv only". Am I correct that the vp-540 uses solvent ink, making the 170 film unusable to us? Thanks!!
