Which paper to cut up for test strips? An analysis

[vdonovan]

I was printing some 16x20s the other day and cutting up sheets of 8x10 to use as test strips and proof prints on the logic that the 16x20 paper was more expensive. Then I thought, well, do I know that's true?

So here's a brief analysis on the cost per square inch of Ilford MG IV RC. I checked Amazon, Adorama, Freestyle and Ultrafineonline. Of those Adorama was cheapest. Adorama sells some paper through Amazon which, oddly, is cheaper than buying directly from Adorama, but they don't have all sizes.

I just checked the quantities I normally buy.
All prices include shipping to San Francisco.

8x10, 100 sheet box $.0066/square inch (Adorama through Amazon)
8x10, 100 sheet box $.0084/square inch (Adorama direct)
8x10, 25 sheets $.011/square inch (Adorama)
11x14, 50 sheet box $.0087/square inch (Adorama)
16x20, 50 sheet box $.0083/square inch (Adorama)

So the answer is: use whatever batch of paper you bought cheapest. It doesn't matter much, just don't buy 25 sheet packs!

I've always used the same paper for test strips as the final print.

Different sizes/boxes may come from different batches and have slightly different characteristics. Considering the amount we spend on gear, film and paper are not that big an expense.

hmm so i now i know where to get 8x10 paper cheaper :]

usually when i print 5x7s i cut and 8x10 in half so i have a 5x8 piece of paper, then i cut that extra inch 1x5 piece of paper and voila! i have a test strip

Absolutely cut the test strip from the same box/package as the print. Also, make the tests by uncovering strips along the LENGTH of the strip, as it will more likely have the same values in various strips. I make them nominally 3/8 inch wide, but younger eyes could probably get by with a quarter inch.
