Many decades ago when the USAF 1951 charts were not readily available, I improvised this chart and still prefer it when comparing images where absolute lp/mm isn't required. A user can measure a largest group and calculate the lp/mm as needed in their own application. The chart is not corrected for dot spread in printing. Resizing the file for posting has corrupted the finer lines. I can send the 374kb file upon request.

He's now offering a Positive version which purports to avoid haloing.
