If it cannot find a suitable match, it will use Adobe Sans MM as a fallback font and adjust its parameters to match the original font as much as possible.įor example, if the original font in the PDF document is Times New Roman 12 pt bold italic, and you do not have Times New Roman installed on your system, Acrobat or Reader will use Adobe Sans MM as a fallback font and set its weight to bold, its style to italic, and its optical size to 12 pt. When you open such a PDF document in Acrobat or Reader, the application will try to find the closest match for the original font on your system. However, Adobe Sans MM is not designed to be a high-quality or aesthetic font, but a functional and generic font that can substitute for any other font in a PDF document.Īdobe Sans MM is used by Adobe Acrobat and Adobe Reader as an internal substitution font for PDF documents that do not have embedded fonts or have missing or broken fonts. It can generate fonts with different combinations of these attributes, such as light, condensed, caption, italic, etc. Adobe Sans MM is a multiple master font that has four axes of variation: weight, width, optical size, and style.
