Chinese Abstract

由於文化創意產業及環保意識的崛起,現今多數的皮製物品不再以真皮為主要素材,大量使用合成皮之皮製物,滿足顧客多樣化、客製化的需求;另一方面,由於仿冒商品亦為全球所關心之議題,因此以合成皮所製作之產品亦須具備相當程度之防偽功能。本研究目的在以半色調技術設計之隱藏浮水印,並利用紅外線偵測驗證浮水印之存在。透過UV平台式噴印機,列印防偽機制於合成皮革之文創商品,並使用數位半色調和印墨材料在紅外線照射下的光學特性差異,構成具多重防偽功能的浮水印。藉由紅外線偵測裝置進行觀察檢視隱藏有資訊的浮水印,以驗證加密效果。並且藉由測試導表了解UV印墨之噴印特性後,找出黑(K)、洋紅(M)、青(C)、黃(Y)印墨比例的最適組合,將隱藏圖案設計成浮水印的形式整合於合成皮革所製作之文創商品的加密圖像中。研究成果顯示,所輸出製作之防偽浮水印,可利用紅外線偵測裝置成功辨識所隱藏之圖像,並且加值應用於合成皮革商品中。

English Abstract

Since the rise of the cultural and creative industries and environmental awareness, the majority of today's leather goods are no longer in leather as the main material, the extensive use of leather synthetic leather material, to meet customer diversification, customization needs; hand, because counterfeiting goods are also issues of global concern, and therefore the production of synthetic leather products also expected to have a considerable degree of security features. This study aims to halftone technology designed to hide the watermark, and use the infrared detectors to verify the presence of the watermark. Through UV flatbed printing machine, printing security mechanisms in the cultural and creative synthetic leather goods, and use digital halftone and ink materials in the optical properties of infrared radiation differences constitute a watermark multiple security functions. By conducting observations of infrared detection device to view hidden watermark information to verify the encryption effect. And by testing the guide table for UV ink jet printing characteristics of the find black (K), magenta (M), cyan (C), yellow (Y) ink optimal combination of proportion, hidden patterns designed to float integration in the form of encrypted image watermark synthetic leather goods produced in the cultural and creative. Research shows that the output of the production of anti-counterfeiting watermark can be detected using an infrared device successfully identify hidden in the image, and value-added commodities used in synthetic leather.
