自從印刷技術被發明以來，它在人們的日常生活中已經無處不在，也許正因為隨處可見的緣故，已被視為是一種理所當然的存在、也容易讓人忽視了這種傳統而古老的技術所創造的美感與價值。研究報告指出，因資訊科技的高速發展使人們生活型態產生結構性的改變，已開發國家的印刷產值幾乎都呈現負成長；國內有專家提出建議，印刷企業可以創新加值的方式邁向轉型之路，具體做法有：發展新的產品、提供新的服務、使用新的材料、提出新的製程等方式。值此資訊多元開放的時代，印刷業者自行取得功能性材料進行特殊油墨的少量調製，並供作加值印刷的生產用途也是一種可行的做法；然而是否可能以較少的成本來達到最大效益？本研究以此為動機與出發點，自行設計單因子實驗，並以兩種變色材料比例（10%與30%）的光變色油墨作為兩種因子水準，再將二者分別塗布在預先印有C、M、Y三原色之實驗用樣張後再加以瞭解：「1.塗布光變色油墨前後的濃度變化」、以及「2.兩種材料比例間的變色效果差異」。透過以上比較後再加以探討：中低材料比例（10%）的光變色油墨是否可能達到近似的效果，進而尋求可節省製作成本的方式。經過實驗與分析後，可將結果歸納為：「1.塗布光變色油墨之後，將會降低紙本印刷品的滿版濃度」、以及「2.水準二（材料比例30%）光變色油墨的變色效果顯著高於水準一（材料比例10%）」等結論。然而較佳的變色效果並不等同於較佳的視覺效果，若應用於套印的場合，應根據實際應用方式以及被印物的底色等因素，決定適當色系的變色材料以及其混合比例。 |

Printing, it has been an indispensable technology in our daily lives ever since its invention. It exists in every aspect of our lives, Perhaps it is just because of their ubiquity, people have taken their existence for granted hence people may easily be in ignorance of the beauty and value created by this traditional technology from ancient times. According to researches, in recent years, due to the swift development of information and communication technology, which has caused a structural change of human lives, the value of output in the printing industry is showing a negative growth in most of the developed countries. There are specialists offered suggestions stating that the print service providers in Taiwan could consider using an innovative and value-adding method to perform an industrial transformation to a higher end, with specific instructions as developing new products, offering new kind of services, using new materials, applying new manufacturing process and etc. In the era of abundant and readily available information, it is also a feasible method for the print service providers to acquire functional materials to make a small amount of specialized ink concoction to be used in value-adding printing. However with these fuctional materials, whether it is possible to reach the greatest efficiency with a lower cost? This research was originated and motivated from this thought, taking experimental research method to compare two sets of photochromic ink by coating them individually on experimental printed matters that preprinted with the three primary colors, and to observe its' difference between: 1. Ink density of Photochromic ink pre-coating and after-coating. 2. Discoloration effects on different experimental factor levels (material ratio 30% and 10%) after light-sensing. By comparing above results then further discuss: if a Photochromic ink with lower density could possibly reach the same or similar overprinting and discoloration effects? After experiment and analysis, the results can be concluded that ＂1. The Solid Ink Densities of the printed matter will be reduced after being coated with Photochromic ink＂ and ＂2. The discoloration Effects that processed by factor level 2 (30%) are greater than by factor level 1 (10%)＂. Nevertheless, the obvious discoloration effects are not equivalent to the better visual effects. When it comes to the occasion of overprinting, the appropriate colorimetric of functional materials and mixture ratio shall be determined according to the actual ways of application and the background color of the substrate that to be coated on. |
