    Dear Bill,

    The emulsion element of any ( monochrome ) coating is 'archivally' incredibly stable, the issue of archival permanence usually relates to the stability of the substrate base, or any 'subbing' applied to that base to allow the coating of the emulsion layer(s). BUT fundamentally, the 'real' archival issue element actually relates to the chemical take up of the base whilst processing, so, Baryta base is the most stable base but takes up the highest volume of chemistry, so needs the extended wash times to make it archivally permanent. The base used on ART 300 is an incredibly stable base and is archivally excellent but is less porous than Baryta and therefore takes up less chemical into its structure, hence the shorter wash times.

    If you balance this to RC products the modern ILFORD RC coatings on RC are very stable and archival, but the base actually has an expected 50 to 80 year life before it could (or will) break down gradually, hence RC product cannot be deemed as 'archivally permanent in the truest sense of the word.

    Regards

    I'm sure your feedback came back as positive as you mentioned, that's because it's a good paper. But I'm also sure the photographers that you contacted to do the tests and evaluation being the elite--no pejorative connotation intended--might have had a self-selecting bias toward a specific kind of paper, and this one paper might have fallen into that bias. Now that you have a bigger sample of people to draw from, you're probably getting feedback more in keeping with the bias of the rest of us mortals, and perhaps the real market ;-) . Again, the paper is fantastic, that's just one of its characteristics.

    Dear squinonescolon...

    Whilst you are correct, we are truly honoured by the people who test our products and many who have indeed deservedly huge reputations and knowledge... but we ensure that our testing is multi-national and spreads across a wide cross section of photography / applications and also includes colleges and students, and home darkroom enthusiasts as well..breadth is very important.

    Its also why I personally check all the feedback good, bad and indifferent on all our products and services on a daily basis from APUG as all of you are our absolute key customer base, users and opinion leaders and we value your experiences with our products and those of our competitors.

    Brother, can you spare a test strip?

    Still looking for a small sample of Art 300--even a test strip would be great. Apparently, there are mysterious forces preventing a sample from traveling between Mobberley and Maryland. Thanks!
