The work consists of nine chapters that describe and examine the topic of design and redesign of the logo. The work begins with the theme of the logo and visual identification of the company on the market. Theories and definitions of products come next as well as its importance to provoke the attention on the market and comparison of importance of the product and the logo. In the chapter of brand I analyse its importance for customers and suppliers as well the means of differentiation on the market while also looking at the brand equity and the importance of legal protection. As a very important element of the existence and the competition is certainly the redesign of the brand. Explaining the design, we are going to find out which are the good features of design and what kind of design is in the marketing and connection between design and communication. We'll process the difference between redesign and styling. Graphic design of the logo will bring us its purpose in the visual identity of the company, as well as typography and colours of the logo, including the importance of the psychology of colours in their selection in graphic design. For easier understanding of design, development, styling of the logo, we need to understand some of the main determinants of creation of the logo, as well as the importance of trends and differences between types of logos. At the end, guided by the theory that is discussed in the last chapter, I examine the business case company and its logo from the very beginning until today.
