The Research is Aim to highlight the value of using typography form and counterform in printed ads, sometimes the designer may be unable to use typography form and counterform with its former knowledge of its basics in design.  The Research is A theoretical framework, followed by a practical design experiment for a set of posters and newsletters to study the relation between figure & the ground through the form & counterform in Typography as an application of Binary Opposition theory in design which aims to create a visual contrast between the spaces in the presence of interrelated relations between the forms that combine harmony and contrast in color, size and shapes.  The study problem can be demonstrated in the following two questions: To what extent the designer can use the typography form and counterform in printed ads? What is the visual relation between figure & the ground through the form & counterform in Typography as an application of Binary Opposition theory in design?  It reached to the result that the using of typography form and counterform is one of the most prolific tools in designing printed ads. it assured that using of form & counterform of typography in design can create different visual rhetoric which can help to attract the attention of the audience.
