標誌就如同品牌的相貌，也是品牌的精神象徵，而標誌的創意表現不會獨立存在著，前端必須先具體擬定訴求，再進行創意表現；訴求與修辭都是為了達到說服的目的，標誌於前端先制定有效的訴求，於後端進行設計時，適切的應用修辭，將能相得益彰，更有效的傳達情意，強化品牌的識別。而標誌設計是以精鍊的形象表現，為了有效的傳遞訊息與強化視覺表現，本研究先探討標誌擇定的訴求，例如強調、承諾是什麼利益，再分析其動用的修辭辭格。

本研究先以文獻來探討標誌設計構成要素、訴求及修辭學原理，再以喜餅標誌為樣本，採質性的文本分析法輔以KJ法析究標誌設計的訴求與修辭表現手法，最後，將喜餅標誌的訴求及主要訴諸、動用的辭格做為歸納；研究結果證實，幾乎所有的喜餅標誌都傳達兩種以上的品牌承諾利益，以及使用兩種以上的修辭辭格來傳遞品牌的綜合訊息，亦即，幾乎所有喜餅標誌設計都運用複合訴求與兼格修辭來強化品牌的形象表達；而喜餅標誌的基本訴求以西方訴求與現代感訴求佔多數，複合訴求的部分較常使用手作訴求；標誌在視覺符號要素較常使用譬喻修辭，視覺語法要素則是使用了較多的映襯、排比與對偶修辭；另外發現修辭的應用也有依隨訴求類型變化之趨勢。
