This thesis explores the effectiveness of information design in promotional posters through a comparative analysis of two design approaches: minimalism and complexity. The aim of the research was to examine how stylistic differences influence the perception of information, aesthetic appeal, perceived professionalism, and emotional response from viewers.
The experimental part involved the creation of eight posters for four events (concert, party, literary evening, and educational fair), each designed in both minimalist and complex styles. These posters were presented in an online survey, where participants evaluated paired designs based on message clarity, visual readability, emotional impact, and stylistic appropriateness. The posters were created using Adobe Illustrator and Procreate, while the survey was conducted via the 1KA platform.
The results revealed that complex posters elicited stronger emotional responses and were more often perceived as suitable for both entertaining and informative events. Minimalist posters, on the other hand, were rated as more professional and trustworthy. Contrary to expectations, complex posters also received higher ratings for clarity and information delivery in several instances.
The analysis indicated that design effectiveness is not solely determined by stylistic choices but largely depends on the type of event and audience expectations. A balanced approach is recommended—combining the clarity and structure of minimalism with the visual impact of complexity—to achieve greater efficiency in visual communication.
