Ink Jet Chart Resolution
This chart, and all our ink jet printed charts have an approximate MTF50 of 5 cycles/mm. Please keep this in mind when choosing the size of chart. Using a chart that is too small with a high-resolution sensor can result in the MTF of the chart degrading the measured MTF of the camera system.
