Typeface legibility: when to use what

Designers often assume that typeface legibility is defined by a simple set of parameters that works no matter the situation in which the typeface will be applied. That is not true. Different reading situations set different demands to the typeface in question. Whether we talk signage, screen or small print on low quality paper, they all have individual issues that need consideration. Based on knowledge provided by type designers, and by the scientific community this talk will discuss the different parameters that constitute a high level of legibility in a given reading context.
