Thanks to Wojtek's recommendation I finally bought Imageprint for my 4800. It turns out my timing could not have been better.
Next week Lexjet will be rolling out a modified matte black cartridge that will work in conjunction with Imageprint.
Once again for those who want the flexibility, you will be able to have matte black and photo black in the same printer. It will replace the light light black cartridge.
For those of you who don't know, to swap cartridges to print matte black and white costs like $80 in ink. Good for Epson. Bad for us.
It is good to see a corporate tyrant humbled by good old American ingenuity.
