FastRip is for MATTE black slot, try a free download of accurip for that printer here,
AccuRip Software for Printing Halftones w/ Epson Printers, the problem with the R1800 if you are not using a rip, is that it will put a clear gloss coat over your entire filme, not only does it waste ink that you don't need to, but it also doesn't expose as well. Hope this helps some.
