Automatic Multiple Master optical sizing in InDesign
Experiment showing that not only are Multiple Master fonts supported in Adobe InDesign, but if they have an optical size axis, the setting to “Automatically Use Correct Optical Size” will indeed work.
This demo shows a Multiple Master version of Benton Modern set at 6pt, 12pt, 24pt, 48pt, and 72pt before and after the previously mentioned “Automatically Use Correct Optical Size” preference is turned on.
Note that in order for Multiple Master fonts to be recognized by InDesign, they must be installed in InDesign’s font folder. Multiple Master fonts installed in the system font folder will not be recognized.
