Does anyone know if you have bulk ink in particular the 4 color package, are the colors of Yellow, Magenta and Cyan the same color as in the 6 color printers?I hate waste but have a brand new pack of bulk 4 color in Epson Inks, i would hate to toss it out but I recently purchased a 6 color printer. In the 6 colors they have a light cyan and a light magenta that I would have to get ink for as well down the road.
