图形和文字是平面设计中进行视觉传达时所运用的主要媒质。纵观种种平面设计的实例,不外乎是图形的、文字的和图文并茂的这三类。只要运用得当,都具有极佳的传达效果。图1是德国设计师(Dietrich Schade)1974年为反对环境污染而作的一幅招贴画。画中无一文字,完全由图形构成。通过极为简约概括的图形,反映了环境污染将给地球上所有生命的生存带来严重危害这样一个基本思想。画面下部的黑色象征着受污染的环境,上部的蓝色象征着优化的自然环境,中间的鱼代表着地球上的所有生命。它居中而放,上面一半在蓝色的背景中,是完整的血肉之躯,表示生命的健康发展,下面一半在黑色背景中,则是一副白骨,表示生命在恶劣环境下惨遭劫杀。鱼头朝上,表达了生命向往美好环境的愿望。画中虽然没有文字出现,但是它要表达的基本思想则是一目了然的,鲜明强烈,令人难忘。图2是美国广告大师乔治·路易斯在越战时期为《君子杂志》创作的 Graphics and text are the main media used for visual communication in graphic design. Looking at all kinds of graphic design examples, nothing more than graphics, text and illustrations of these three categories. As long as properly used, have excellent communication effect. Figure 1 is a poster by Dietrich Schade in 1974 against environmental pollution. No painting in the text, completely composed of graphics. Through a very concise outline of the picture, it reflects the basic idea that environmental pollution will bring serious harm to the survival of all life on Earth. The black color in the lower part of the screen symbolizes the polluted environment, the blue in the upper part symbolizes an optimized natural environment and the middle fish represent all the life on earth. It is centered and the top half in the blue background is a complete flesh and blood, indicating the healthy development of life, the bottom half in the black background, it is a bones, said life in bad circumstances miserably robbed. Head up, expressing the desire of life for the good environment. Although there is no written text in the painting, the basic idea it expresses is clear at a glance, vivid and unforgettable. Figure 2 is the American advertising master George Louis in the Vietnam War for the “gentleman magazine” creation
