實體浮水印的應用大多以文件複印後呈現文字藉此宣告版權，隨著文化創意產業的觀念在台灣的興盛並為產官學研各界的重視，許多商品的設計也朝向少量多樣的客製化發展，個人化商品的使用範圍廣泛，亦可以在筆記本、日記與重要文件上附加個人化的創意設計。本研究目的在提出以混合網點數位浮水印技術設計個人化圖像與文字內容的浮水印文件，並在文件複印後使圖像、文字黑白反轉。本研究是以調幅網點與調頻網點混合來設計圖像與文字內容的浮水印文件，複印後黑白反轉成負像，使文件在複印或掃描後改變文件上的圖像與文字內容。研究結果顯示本研究所發展的技術，無論是在重要文件、筆記本內頁、證書等紙本出版品，圖像與文字經複印後即可黑白反轉原稿的實體浮水印，藉此文件可以得到版權保護，並增添個人化出版品的創意及趣味性。

Most application of the watermark are using the text or figurative pattern to declare the copyright when the original document is duplicated. As the cultural creativity industry becomes more popular in Taiwan, the product design can not only be customized, but also inspire personal creativity. The purpose of this research is to design a personal image by using watermark which consists of both amplitude modulation dots and frequency modulation dots. When the document is photocopied or scanned, the watermark on this document will be reversed positively or negatively. The initial result reveals that this technology will provide a novel method of copyright protection; moreover, it will expand the creativity and interest for personalized products.
