I have a MH-871 and OSX and Signcut. I have a large, 46"x120" sign I want to cut, so it will have to be tiled. The thing is we want to use the reverse- IE not the actual letters themselves but the background with the letters cut out of it- However every time I try to let signcut tile the image, it keeps overlapping the panels and cutting letters out of the previous panel along the edge. Anyone ever tried this kind of application? Do I just need to tile it myself in Illustrator and then print each tile seperately? Also wondering if once I get to this point I am leaving a nightmare for myself in terms of applying it to the window dry, trying to line up seams and so forth. thanks!

I did this and it is working mostly great but it keeps reverting the vinyl size back to 18.5" when it can take a 30" roll- how do I trick signcut into accepting a 30" roll?
