turning image into a negative

Being in the Heat Transfer business, there is a new paper out that rids the paper print called "Image Clip", it has a procedure that to make it work. Printing a mirrored image on transfer paper and printing another image with laser but a "NEGATIVE". I have suite X4, any quick ways to make the image using my Corel, their instructions is only in Photoshop, I prefer Corel? Thanks, I'll look for answers, this is my 1st post.
