I use their laser/clear paper.
The main thing to understand is that when you make designs in Photoshop, for example, any areas you want to make white or pale coloured will print out with clear because
there is no white ink
There are two ways to work around this.
1. Use the white back transfer and trim carefully to the edges of your design. This is easy on simple designs.
2. Paint a white panel onto the model where you are going to place the finished transfer. This works better if you have a complex curved edge design.
