Digital BW, The Print

Hi Daniel,

To be honest, I really don't know what my IP produced B&W prints look like under the multitude of different light sources out there. But, I can tell you that in indirect natural light (my living room) or incandescent roomlight my B&W prints look fine; no color cast.

The Epson driver printing B&W will most definitely introduce some form of color cast...in my experience, anyway.
