Summary of Issue: 18 point for image of text
Comment (Including rationale for any proposed change):
Image of text can be different actual size even if an author set "18pt" for it. When using 96ppi, 18pt image of text is large enough to be considered as large scale of text. But when using 72ppi, which is most popular setting among designers, 18pt image of text is smaller than 18pt text(1.5em or 150%). 



See examples at:

Which size is 18 point for image of text? Designers are confusing as it is not described in Understanding or any other documents. Some are using 72ppi and others are using 96ppi. Please clarify it.

Proposed Change:
