I have been using the substance holographic vinyl for awhile and not had to do any adjustments with our cutter to read the registration marks and I can even do reflective and clear with no problems. I have a roll of the substance chrome vinyl I have been trying to get it to read the marks for a few days and had no luck at all. I have tried putting white vinyl around the edges of the marks, tried matte vinyl overtop and even bought the yellow opos filter. When I did that I tried calibrating the media and it is saying the mark will not be readable and the values it gives me are too high to be entered. Does anyone else have this problem and done anything to solve it? I have about 6 prints on chrome I need to cut so I am hoping I can get something to work.
