    best method of processing fibre base paper

    Hello All:I'll be processing about 50 sheets of B&W fibre base paper next week and I have two questions. 1). Which method ,of the various ones out there,is the best to use in terms of fixing and print protection as far as archival keeping is concerned and 2). Is the method of processing and archival print protection dependent on which make of paper I use?.

    Thanks in advance,

    Doug

    The techniques you use to process fibre based paper are not Brand dependent, but rather "weight" dependent. You fix and wash single weight paper for a longer period of time than double-weight paper.

    For common double-weight fibre paper (Ilford, Foma, Efke, Kentmere, etc.) After developing and stop bath, fix for 3 to 5 minutes each in 2 fixing baths, one right after the other, then treat in a washing aid such as Kodak Hypo clear (follow instructions on box) and wash for proscribed time. This is my routine. Yours may vary. It is common practice to discard first fixing bath after "so many" prints and move 2nd fixing bath up to 1st position and make fresh 2nd fixing bath. You may use a water holding bath after 2nd fixing bath, and treat all prints together for hypo clear and washing. For true archival processing, you need to test your prints for hypo residue with a test solution, available from common vendors, to ensure your wash is adequate.

    You'll need to do a first wash before the Hypo Clear (5-10 minutes). After the Hypo Clear another, final, wash of 10-15 minutes is needed.
    For archival purposes, toning in a dilute Selenium Toner is recommended.

    I believe that Ilford has done some extensive testing in so far as what is needed to insure "permanence" of both prints and negatives. They have published their recommendations, perhaps on the Ilford site. I am sorry not to be able to provide a direct link for you, but a simple google search should be able to lead you to the most recent Ilford data.

    That is not the whole story. First, that method has very
    limited application. It is best used if one has A print and
    needs it in a hurry. I can't imagine any one using the
    that method save for that purpose.

    Second, the capacity of that one liter one fixer is 10 8x10s.
    That is way down from the 40 8x10s possible using the
    two bath method. Ilford does recommend the two
    bath method. Dan

    best method of processing fibre base paper

    Hello:Thanks all for responding.If someone could give me the web address for michael and paula it would help a lot.I just read an archival processing method in the Darkroom Cookbook which used Berg Bath after the Selenium toning to remove excess toner and a final treatment after washing with Agfa Sistan of which I have 6 bottles I recently purchased.Any thoughts on this method?.

    Thanks again,

    Doug
