If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text except for the following:
Customizable
The image of text can be visually customized to the user’s requirements;
Essential
A particular presentation of text is essential to the information being conveyed.
Note
Logotypes (text that is part of a logo or brand name) are considered essential.
Text is pure text, not an image, unless it is a visual customisation, a particular presentation or a logotype.
