Digital BW, The Print

I have tried and experienced the same results with spray coatings and 
am surprised that there are no mainstream products made specifically 
for ink prints.

The RC papers are quite durable on their own.I have a luster color 
print tacked to the outside of my house for 4 months exposed to rain 
and sun and, to date, no change. A matte print in on the sun porch 
has also not changed.

Glass is definitely not my first choice. However, in many situations, 
it is a must and is required for exhibits and galleries. For 
permanent display, if your matting is not all well glued together, it 
will eventually warp outward without glass to keep it flat. 

The out-gassing is still an issue. Even forced dried prints (2200)
have shown a slight but acceptable deposit after several months.
