    Question on freezing paper

    Question on refreezing paper

    I may go several months with out getting any printing done Because my basement darkroom doesn’t have temperature and humidity controls paper tends to go bad on me. The obvious solution would be to refrigerate the paper but humidity in the average fridge might be a problem I want to freeze the paper ( I have a freezer ) and take out only what I anticipate using Break the factory seal open the plastic wrap and put some in a paper safe. Reseal the paper in the black plastic and wrap the box in several layers of plastic wrap and put it back in the freezer. Does this make sense or am I introducing another problem?

    I suppose if you are really worried about humidity then you could use one of those vacuum sealing things if they make wide enough ones:

    Offhand I'd think that a ziplok should do plenty well if you let the bag come up to temp before opening it.

    I don't understand why you think that humidity in a fridge would have a detrimental effect on paper.

    This is what most of us do. The plastic wrapping that the paper is supplied in is sufficient protection for the paper, an extra plastic bag is advisable to protect the box.

    [ In the summer in Ohio the humidity is high enough to ruin paper at room temperature I have a dehumidifier running all summer long Opening the door on a fridge you will see a fog of condensing moist air and this is a new fridge.

    Assuming you have a typical frost-free refrigerator, actual humidity conditions are exactly opposite of what you describe. The refrigerator compartment has very low relative humidity and the freezer compartment runs high. In fact, during defrost cycles, the freezer compartment can approach 100% RH.

    Best approach is to place your paper in a zip-sealing storage bag and keep it in the refrigerator compartment. Plastic bag protection is needed only to guard against surface condensation when you open the refrigerator door or remove the package for warm up prior to use.

    Then there is always the advice of my teachers. Make more prints more often. It will make you a better printer. I know life has many reasons not to do that. Some times it is simply a matter of priorities.

    When you say your paper goes bad, what does bad mean to you? Please describe bad and name the paper you use. I live between Akron and Cleveland in Ohio and it is humid, 97 percent this morning. I have not had the paper problem with Kentmere Fineprint FBVC in all sizes to 20x24. Previously I used Kodak Polymax FBVC and do not remember any problems. I store the open paper in the dark plastic bag within paper safes of the appropriate size and unopened paper in a metal flat file. Our rural basement problem is mice rather than humidity. I freeze my film but have not had a reason to freeze paper.

    I was going to ask a few of the same questions. Are you sure temp and humidity is wrecking your paper, or does the basement darkroom have a light leak. Or maybe safelights. Or, are your factory sealed papers ancient to begin with?

    Yes, I routinely break up boxes of paper and re-wrap in sheets of 25 or 50, in extra black envelopes lying about. Sealed with duct tape, spare cardboard envelope, then two trash bags withas much air sucked out as possible, then taped as well.

    Do not open a frozen package of paper until it is thawed and up to room temp, for obvious reasons.

    I do not refreeze thawed packages, partly out of fear of condensation again, and partly out of superstition.

    I live in Mansfield Ohio and our humidity is probably the same as yours
    I had some Ilford warmtone VC Fiber develop a fine light fog with a pattern that resembled grain or reticulation, But 5 or 6 sheets into the box the condition ceased. So freezing is a matter of economics also. I admit some of the paper is by now 3 to 4 years old but showing no sign of age fog. I have had RC lose contrast by almost a grade and a half. I didn’t bother trying to save it as I thought it was probably just too far gone.
