The Association of Registered Graphic Designers (RGD) has released AccessAbility 2: A Practical Handbook on Accessible Graphic Design. This book is meant for anyone involved in the process of designing communication materials. This is a broad group of individuals, including professional graphic designers, clients, educators, students and many others.
The Handbook addresses how to plan a graphic design project to help ensure it is as accessible as possible for the intended audience; what special considerations are needed to make for accessibility across various media; and how our desire to communicate effectively with people of varying abilities and potential impairments translates into specific design decisions.
AccessAbility 2 comes in two versions: the Revised + Supersized (Full) and the Essentials.
