Use True Text
There are two main reasons to use True Text over Text within Graphic. Text can be transformed into sound through voice synthesizers in screen readers. Text can also be enlarged by screen enlargement or magnification software without loss of quality.
True Text enlarges better, loads faster, has lower bandwidth requirements and is better with search engine optimizations.
Example: The enlarged image of the word "University" is difficult to read because it has become pixelated.
Example: True Text of the word "University" enlarged
