The Creative Expression Of Geometric Figures In The Design Of Public Welfare Posters Based On The Op Art Style

With the progress and development of society,the design of public welfare posters needs to keep "freshness" constantly.Op art style patterns make posters diversified and meet people’s demand for new style public welfare posters.Op Art is a style based on geometry.The use of multi-element collocation of graphics and colors can create images that seem to be moving or flashing.Op Art can cleverly use dots,lines,and face images to produce bright visual effects,providing infinite possibilities for poster design,becoming a visual symbol that effectively conveys human spiritual culture and a communication carrier of modern design culture,in the creative creativity Inject culture,thinking,and spirit to achieve direct dialogue with the soul.First of all,the research of this article is mainly based on the related theories of the geometric figures of the Op art style.It is concluded from the development status at home and abroad that the domestic Op art mainly focuses on theoretical research,with relatively few practical applications.By consulting related documents,the Op art is summarized.The artistic characteristics and creative expression of style geometric figures,systematically analyze the principles and creative methods of the optical illusion and dislocation spatial sense of Op Art graphics,extract the three-dimensional and flickering sense of Op Art,and use plane composition as the entry point for poster design.,To explore how to use geometric figures to increase the three-dimensionality and fluidity of the picture,but also to retain the effect of shallow visual illusion.Secondly,investigate the current status of public welfare posters,analyze the style and presentation of current public welfare posters,sort out the themes of public welfare posters,and compare public welfare posters in Op Art style with ordinary public welfare posters based on the development status of public welfare posters,To explore the necessity and possibility of its existence.Finally,with "white pollution" as the theme of public welfare posters for research and application practice,the Op Art style geometric figures are applied to the public welfare posters.Under the interaction with comprehensive materials,the theme of public welfare posters is combined with visual image,emotional transmission and Innovating in spiritual culture and other aspects,based on the feasibility of multi-form design of public welfare posters,provides a certain theoretical basis for the development of public welfare posters in the future,provides new ideas and injects new energy into modern poster design.
