Adobe heiti std is included when installing Adobe software. If this font is used for business, does it need to purchase a font license?
You don't need an additional font license to use Adobe Heiti in a commercial project. From the Adobe Type licensing FAQ:
Q. Can I use Adobe fonts for commercial projects and client work?
A: Yes, Adobe's standard font licensing agreement (EULA) allows for both personal and commercial use, sales, and distribution of designs and documents which are created using the font software. This may include printed materials, logos, and rendered content like photographs, film, video and bitmap graphics.
If distributed, the design should not contain the original font, but can be converted to vector outlines, rasterized, or subsetted and embedded in an electronic document like a PDF or eBook.
I hope that this helps; let me know if you have any other questions!
