Your problem is with the matte black inks. I think it contains some greasy component that keeps it from be locked into the SuperSauce. If you use the Luster Epson profile that will use photo black ink. That profile is richer in color than the photo gloss profiles. If you are using the classic film you can skip the de-slime step and apply a quick sealing coat of the SuperSauce Solution. Use single strokes quickly and do not brush hard or you will dissolve the image. Just flow it on and let it dry.
