Switching papers and longevity aren't the issue. The fact is that it
appears ABW gives greater dmax than when printing in color mode via a
standard color managed workflow. I'm not the only one who has noticed
this. As this is the case with EEM I suspect it will be with other
papers also.
No, this is a function of what inkload is required to get maximum black. If AWB can heap more black on and make it darker, it comes out ahead (jsimply from a mismatch in the Epson AWB/Color drivers, this does NOT happen with the Canon iPF or HP Z printers). If the black applied by Color Mode is sufficient to reach max black on a given paper with the Epson driver, then either is acceptable. Thats why a paper that reaches max black at reasonable ink levels, and the optimal media setting, are important to using color mode for B&W printing on the Epson two-gray printers.
