I'm not entirely certain that I'm understanding what you mean.
As long as you can convey the information (pressure application, printable area) in customize-able image elements, upload zones and text, the Fancy Product Designer should work for your scenario. To get an idea of what you can do with the Plugins you can take a look at the demos.
You could also maybe post a few concept sketches? That way it would be easier for me to help you.
