Have you checked your PVC card printing machine manual to see if it supports borderless printing and what settings to use. It may be just a device driver setting you need to set. You did not even note what print machine you have.
i have a fargo hdp5000 and the programs with it are very complicated and don't work well. I try to priont from photoshop but the colour come out scrambled. The ICC for this printer comes up automatically the wrinitng is clear but the images come out all wrong.
Post a screen capture showing your Photoshop Print settings and your printer settings. You do not want both managing the print colors. Settings must work together or the colors will be messed up
