I am trying to find a font that I know is an Adobe font to activate it and I cannot find it (a colleague uses it and has said it is an adobe font).
The font is called Iowan Old Style Roman.
The Iowan Old Style type family was released by Bitstream in the early 1990's. It is not available in the Adobe Fonts Service. Monotype acquired the Bitstream company about 10 years ago. Does your colleague use CorelDRAW? For many years that application has included a lot of Bitstream fonts, including Iowan Old Style. Bitstream's fonts often have a "BT" suffix included in the typeface name.
She is using Adobe InDesign and said it was a system font when I asked her about it.
She must be using a Mac.
