Digital BW, The Print

Mark,

What do you know about the brighteners being used by Breathing Color in their Chromata canvas products? I've been meaning to ask you that for a year now.

They claim these brighteners of theirs are revolutionary and don't suffer the same burnout issues as obas. Are they just kidding us or,  is there some potential for other papers using this kind of whiter?

When low levels of light strike the TiO2, free radicals are released that eventually embrittle the resin coating. The prints become much more susceptible to cracking when the plasticity of the coatings is reduced.
