Laserman 70, try your free program, it might work… but in all likely hood, it is doomed man, it is doomed. You are for asking advice and then you say you found a program that does, well, who knows what it does. You don't because you just found it, and I think you want to plot some vinyl, right? Well Corel or Illustrator are good for designing and either plugins or a bridge program will get the plots out for you.
Photoshop does what it does with excellence, but it does not do what Illustrator or Corel, or Flexi or any other vector program can do.
