the last reference talks about electrophotographic printing processes (not pigment inkjet) in combination with polymeric varnishes or lamination foil. This is vastly different from what we are discussing here.
“Colour prints with a surface protection of polymer varnish or foil protection are very unstable, causing deterioration of colour, contrasts and colour balance. “
This is not even true in all cases as certain varnishes can strongly increase contrast. But of course colour accuracy suffers.
Reference is mostly made to Wilhelm Imaging Research in these documents, and I am not sure that WIR have ever done tests and measurements on prints treated with Hahnemühle Protective Spray. Not sure whether Aardenburg Imaging have done such tests.
Hahnemühle Protective Spray is not a varnish, hence measurements would need to be done to establish how much it will alter colours. I have no spectrophotometer hence I can’t do it.
I have no good answer to the question whether it’s worth the time and money. But I want to believe that it’s better than bottled water from that very special place or even canned air which is then shipped half around the globe. 🙂
