In JMP 10 and later for Windows, when you save a report in PNG, TIFF, or JPEG format, you can choose an image DPI setting of either Default or 300.
If you select "Default", the OS default setting will be used, and if you select "300", 300 DPI will be specified as the resolution.
In JMP 13 and later, you can choose from "Default," "300," "600," and "1200."
