I had bought a pack of Sunnyscopa thin film waterslide decals from Amazon about a couple of months ago for a project. At that time I printed some art on it and it turned out fine. Fast forward to today and I'm ready to apply my decals but when I printed them out, the paper darkened. The art is all black (inserts) but the decal is not usable due to the darkening of the paper. It's almost as if the paper is too sensitive to the printer and is picking up residual crap. This does not happen when printing on regular paper. Perhaps the decal paper has gotten old? Anyone have this problem and if so did you find a solution?
