Digital BW, The Print

Peter,

I can't tell what the problem might be.  Be sure you're using "No Color
Adjustment" and there are no other profiles used in the printing.

The scan you posted looks light there are no highlights, but may be that is
just the scan.  Be sure you're getting perfect nozzle checks.

I'd also be sure the driver is the Epson driver.  Some computers have
abbreviated drivers that act differently than the Epson drivers.

I'll send you the curves off list.
