First of all, the typography does communicate messages of all kinds. Still the typography produces an important contribution to the company's visual identity, partly by establishing a uniform writing partly by establishing a sense of quality.
Helvetica Neue is the typography of Dansani and should be used everywhere possible. On Dansani's website Arial is used and this font should be used everywhere it it is not possible to use Helvetica Neue. Both typographies are sans serif i.e. letter stroke without serifs (small projecting features).
If text is used on a image background there should always be large contrast through either colour or size/thickness of the font
