You shouldn't have a problem with that plotter cutting window film. You may need to play with the blades and settings for different films. The most important thing is having a wide range of pressure settings. Higher quality plotters do a better job on films as they can be a pain. Take your time and do plenty of test cuts. We use a 60" DGI for cutting and 25 degree blades. I have it on my list to upgrade to a Graphtec.
