Holding a sample piece of UPW and regular commercial screen material next to an untouched piece of "triple pass" BOC reveals that the BOC in definitely not white. (not sure why I never noticed this before)?



Has anyone researched the Munsel shade? (N9 or N8.5)?


Has anyone RGB'd a piece of it to see how neutral it is?

As you have noticed Rob, BOC isn't as white as a good white latex paint. However, just what color/shade your BOC is will depend on what brand it is, and probably even what lot number it is. BOC is made to block out light; as far as I know, it's not made to any demanding color specifications.


All I can tell you is that the 'White Budget Blackout Cloth' I bought from JoAnn's measures thusly:


Budget White Blackout Cloth - coated side (smoother)

L*a*b* 90.24 -1.05 0.36 (N9 and just a smidgen out of neutral specs)

RGB 225 228 226


Budget White Black Out Cloth - uncoated side

L*a*b* 92.11 -0.40 0.08 (N9.2 and very neutral)

RGB 232 233 232

Thanks Harpmaker,


After experimenting with at least 5 different mixes over the last 3 years, I have always wondered why I thought BOC "untouched" still had something to offer.


I've come to the conclusion that BOC is a GREAT stand alone surface for those that want a bit of gray to help the blacks, but still retain the whites. I've been looking for an N9 for a while and had the sneaking suspicion that it was close. Little did I realize how close.
