Digital BW, The Print

I print BO on heavyweight matte paper and also on watercolour radiant 
white. Don't have any numbers, but as the black ink is pigment based, I 
believe it last quite a long time. Epson dye-based inks last about 26 
years on heavyweight matte, so the grey ink should at least last as long.
Once I made a test print a  on HWM and coated half of the print with 
Golden acrylic varnish after spraying the print with W&N artist's 
fixative. Then I placed the print outside to direct sunlight. The 
unvarnished part turned to magenta in 2 two days and the coated part 
lasted 2 weeks. Might have lasted longer, but then came the rainy season :-)
