印刷鉛字與點矩陣全像片光影變化效果之整合加值應用

Abstract

印刷術是中國四大發明之一，十一世紀時宋朝畢昇發明活字版印刷，使印刷技術進入一個新的時代。活字版印刷西傳歐洲後，古騰堡整合活字版印刷技術發明鉛活字版印刷；到了十九世紀，鉛活字版印刷術再由西方傳回中國，並活躍至電腦排版的發明。然而電腦排版的發明取代鉛字活版印刷，鉛字轉變為具歷史文化意義的文物，且多半用來放在收藏盒裡展示、收藏；而鉛活字印刷術之凸版印刷原理與點矩陣全像片製作的過程皆有「壓印」效果可相互呼應。因此本研究之目的在於將印刷鉛字與全像技術結合，將印刷鉛字做成個人化印章的加值產品。本研究欲以預覽程式模擬點矩陣全像片之光影變化效果，並建立一光影變化效果數值為光影變化效果的評估，當數值越大表示點矩陣全像片之光影變化效果越豐富；反之，效果越不明顯。透過預覽程式模擬與光影變化效果評估後找出最適當的效果，再將點矩陣全像科技結合印刷鉛字之表面以減少製作之誤差。最後，再製作一加值設計印章殼使印刷鉛字能更符合使用者習慣，且能顯露出全像科技與印刷鉛字之結合效果，使印刷鉛字能走入日常生活，並使此加值產品更具獨特性與增加其品牌保護的效果。The printing technique was one of the greatest inventions in ancient China. Around the 11th century, the world's first known movable type system was created by Bi Sheng in Song Dynasty, which brought the printing technique into a new age. While movable type system made its appearance in Europe, Johannes Gutenberg developed European movable type printing technology around 1439, and was widely used until the debut of computerized typesetting. As the traditional movable type printing technology was replaced by computerized typesetting, it turned out to be a historical artifact, displayed in the cabinet or museum. Also, movable type printing is a kind of relief printing which has similar functionality to the pattern embossing by dot-matrix hologram. The purpose of this research is to convert this movable type printing technology into a personal value-added signet with anti-counterfeiting capabilities, integrating this traditional printing system with dot matrix hologram. Firstly, this research uses a preview program to simulate the iridescent effect of dot-matrix hologram. Then, an index can estimate the iridescent effect of a dot-matrix hologram. Secondly, design a transparent acrylic shell for user-friendly purpose and can display the combination effect of movable type and hologram. This research converts the traditional type printing technology into a unique value-added product with the function of anti-counterfeiting.
