I have an R31 cutter, and am using inkscape,and LXI apprentice. I have seen several how to's videos and such on how to lay the vinyl on top of the registration marks to actually layer the graphics. I have see videos on how to make multi color vinyl designs, but nothing in between those. I am totally lost on how to put a registration mark on and cut out three different layers on a vinyl design. How do I cut them up seperately and have them go back together perfectly on the assembly table. I have heard of people using custom built light boxes and stuff, but I would like to know how so I can do it.
