The MIS original Quad inkset shared the black ink with the original MIS Archival color pigment inkset. However, the old quad and the newer VM and FS quads have no common inks (although the quad ink is used at different dilutions in the VM inkset). All VM and FS inksets use the same black ink. It is a co-solvent ink that has a stronger smell than the other quads are Archival color inks. The FS midtones are not shared with any other inkset. The VM midtones are not shared by any other inkset. The FS-N cyan and the VM-S (sepia to neutral) inksets share the same cyan-position ink. All FS inks are supposed to have the same densities as the original PiezoBW inks. The new PiezoTone may have slightly different densities. The FS, VM and PiezoBW (now Sundance?) have the cyan (darkest gray) ink density in common. The next lightest gray -- the magenta -- is different between the VM and FS inksets. They are not interchangeable. Don't take old ink density percentages at face value. The numbers just designated which inks were darker or lighter. The companies did not want to divulge their mixing ratios, and the mixing ratios and resulting reflectance densities are not the same or in a linear relationship. > Is "DD Black" the same as the FS K, for instance? No, the DD black blocks up the blacks badly, at least with the curves written for the Vm inksets. On different papers and with different profiles, it might be fine. The VM/FS K fade and warming performance on EAM was/is better. >I'm beginning to see why people pay big bucks for a RIP... >lots of work ahead. Professional labs often can't take the time to fiddle with things, and they use lots of different papers. I don't use that many papers, and I find the ability to re-profile my system for a new batch of EAM to be useful. If I relied on someone else to profile the system, I'm not sure it would get done. Another factor for your 7000 is that the Epson driver does not have the best blacks on that printer -- unlike the situation with the desktop printers. Good luck. Paul http://www.PaulRoark.com
