What color space for BW digital photography and printing

I’m wondering about color spaces and how they affect working with BW digital images and digital printing (working in PS and LR).

 

I’ve been thinking that the grays are probably more limited by the bit depth (65,536 shades of gray for 16-bit vs. 256 shades for 8-bit.) than by whether or not you’re working in ProPhotoRGB or AdobeRGB, but that’s just a guess on my part. Does anyone know if one of these two color spaces really better than the other, specifically for BW images and digital printing (I'm printing to an Epson 3880)?

 

Thanks, David.

    David,

    I personally have printed on the Epson 3880, and have a Epson 1400 for my home and personal use. I would recommend ProPhoto RGB, and doing the 16bit. The ProPhoto RGB does better with color, so this may not really affect the BW images you have. Just to be safe I would use the ProPhoto RGB.  The printer can handle it, and I have had no problems with it thus far. FYI: The only problem I frequently have is that the blacks print extremely dark on the Epson (its known to be a problem), so I am always altering the blacks in test prints. You may have already experienced this.

     

    This link may better help explain the differences of Adobe RGB vs. ProPhoto RGB :

    For the Epson 3800/3880, you might gain some insight from Eric Chan's print workflow guide. In it, he goes over several different black-and-white workflows and discusses color spaces.

     

    I believe he wrote the guide before he joined Adobe, but Eric is now one of the key engineers behind Lightroom and Camera Raw.

    I'm probably on the far end of your opinion spectrum but I just completed a big print job (2 ea. of over 1600 9x9 b/w aerial scans) using our fairly new Epson 4900. Before I started I called Epson and asked them how to approach printing grayscale with their machine. All my other work (mainly color to a HP Z6100) has been in SRGB 8bit and their response was - convert to that. So I did, and the results were outstanding. But, I also had an overall darker print than I had onscreen by almost 20% +/-, using a Spyder 3 Elite calibrated system.

     

    So yeah, I guess you could worry about these monsterous color spaces and bit depths, there is beauty is keeping it simple...
