Greetings all;
I would like to know how to make registration marks in SCAL? Iam trying to make a two color vinyl project and I need to be sure that my two images are aligned. Can someone explain what I need to do to create the registration marks.
Thanks in advance
Jerry

I just use small shapes on a separate layer. Below is an image of a 3 color file that I cut for my son's Cub Scout Den. I imported the file just like it shows, then cut each color leaving the beige squares in each cut. You can also use this when cutting multiples (second image).
