If you have a fully licensed copy of Measure Tool, you can use any supported instrument to read density and dot gain, as well as to do some basic quality control checks.

Once you have read your testchart, you will see Optical Density, Gradation Curve, and Dot Gain options in tabs across the top of the measurement window. Each tab will give you additional options, such as the filters or standards to use. You can export your information as a text document for use in programs like Excel.
