Nate, nice analogy....but, only very fine human hair is 75um (.003").... I think avg. human hair is 200um. Interestingly enough, I think standard copy paper is .003" thick. If you buy black and white sheets and interlace them, you will have a very nice 7 lp/mm target. (looking at the edges)
BTW, if you can resolve this target, its said, you can resolve 7 lp/mm, as the white line counts as a line.
I think Kodaks min. order is $15k for cut-to-size? too steep for me....
