Digital BW, The Print

I recently purchased an Epson 4800 and have been very satisfied with my 
B&W prints thus far, except for the annoying fact of having to switch 
between matte black & photo black ink cartridges. I came across 
Colorbyte's Phatte Black program that allows one to have both matte & 
photo black in at the same time by replacing the light-light black 
cartridge. Does anyone know if this is a stand-alone program or is it 
solely an add-on to the ImagePrintV6(or V6.1) RIP? It would be great to 
take advantage of this program w/o having to pay almost $900 for the 
RIP. If it is an add-on to ImagePrint does anyone know of any similar 
programs that accomplish the same thing? Thanks in advance for any 
insights or advice.
