Between Aardenburg and Wilhelm, there's plenty of information out there regarding the lightfastness of various ink-paper combinations (in general HP Vivera > Canon Lucia > Epson Ultrachrome) - but, of course, that's only part of the equation. Degradation by ozone and other atmospheric pollutants is just as much a factor in the deterioration of prints (more so in dark storage, or in dimly-lit homes and other display environments), and microporous inkjet coatings are much more susceptible to this than uncoated papers and gelatin prints, due to their greater surface area. Spray coatings and laminates mitigate this somewhat (this, and the physical protection from scuffing and moisture, may be more important to inkjet prints than the increased UV protection provided by these coatings), especially if the spray is applied to the reverse and edges of the print as well as the front, but how effective are they, really, at sealing the billions of pores in a typical inkjet print? And, of course, it's no good having a permanent print if the substrate deteriorates from atmospheric contaminants, from remnants of the print method, or from the ink or pigment itself - platinum prints may last forever, but a lot of century-old platinum prints are now extremely brittle and fragile, if not stained and falling apart, due to the catalytic conversion of gaseous sulfur dioxide and water in the atmosphere into sulfuric acid, which attacks the paper, despite leaving the platinum itself untarnished.
So, in a similar vein to Aardenburg and Wilhelm for lightfastness, do we have any good sources of information at the moment regarding the chemical and humidity resistance of various print method/ink/substrate/sealant combinations? As in, actual tests on specific combinations, not just general and theoretical documents?
