pmu said:Hi,
I have a change to buy a lot of older Ilford multigrade 3 paper, but I should ask this; the paper is about 10-15 years old, ...
What do you think about this? Could there be some defects in the paper? If yes, what would it be?

To give you an idea. Not long ago I opened and printed on a box of DuPont Varigam, single weightpaper, Use by date 1956 - NO FOG!

pmu said:OK, can you help me - how do I test that paper?
-Fogging; taking a small slice of paper in total darkness and developed it straight away and then compare the result for undeveloped slice? If no difference = the paper is not fogged?
-Contrast; just checking if I get real blacks and whites to the same paper?
-Anything else?
Make sure you fix the undeveloped slice, but yes, this would give you a good idea on the fogging. As for contrast, I don't know how you can compare it to the paper's original characteristics, but you can easily compare it to fresh paper to see how it holds up.pmu said:-Fogging; taking a small slice of paper in total darkness and developed it straight away and then compare the result for undeveloped slice?
