dc.description.abstract 移印屬於特種印刷的一種,其對承印物的適應性廣泛,尤其在小面積、凹凸面的產品上進行圖文印刷具有其他印刷版式無法取代的優勢。感光性樹脂材料為非銀鹽系的感光物質,屬高分子聚合物,其可因吸收光線而引生光聚合作用,製版速度快,污染少,可有效提昇製版品質與製版效率。由於移印的承印材料廣泛、印製作業特殊性,有別於一般的印刷方式,移印油墨厚度的轉移更應依據產品特質作適當的調整,使得移印版印紋網孔深度的控制更顯得重要。唯目前國內移印製版作業並未建立標準模式來控制移印版網孔深度的穩定性,製版作業人員多利用主觀經驗作為評斷標準,因此本研究目的希望能透過實驗,針對影響樹脂移印版印紋網孔深度形成的因素進行探討,建立一套掌控印紋網孔深度的方式,以增進移印製版品質的穩定性,俾提供移印業者作業管控的參考。本研究採兩因子實驗設計,兩個因子分別為:1、製版時選擇之網屏線數2、製版時控制印紋深度之前露光時間,網屏線數因子設有4個水準,前露光時間因子則有5個水準。兩因子4×5實驗設計共有20種不同的實驗處理組合,各處理組合以隨機的方式決定實驗的先後順序,並分別製作45份樣本,故實驗結果可得900份樣本。經統計分析與討論,本研究的重要結果與發現:1、樹脂移印版印紋網孔深度廣泛,實驗處理深度值介於14至77μm之間,足於應付各類移印作業的印紋深度所需。2、印紋深度與前露光時間增加呈反比,也與網屏線數增加呈反比,製版時可利用減少前露光時間或換取較低的網屏線數底片以增加印版印紋深度。3、兩實驗因子對印紋深度控制有交互作用存在,隨著前露光時間的增加,網屏線數增加對印紋深度值減少的影響愈不明顯,甚至當前露光時間增加至6秒、8秒時,網屏線數的增加對印紋深度值的減少幾乎沒有影響。同時,隨著網屏線數的增加,前露光時間增加對印紋深度值減少的影響也愈不顯著。 zh_TW
dc.description.abstract Pad printing belongs to special printing with a wide range of printing substrates, having niche especially in printing small area and uneven surfaces. The photopolymer is one kind of non-silver sensitization material, it polymerizes by absorbing light to have high plating-making speed with few environmental pollution. By versatile printing substrates, pad printing needs to control exactly the relief depth of printing plate to have ideal ink thickness transferred. With still no having standard procedures to keep the plate relief depth control stable, the only way is by operator’s own experience, that is the purpose of this study to form a method to control the plate depth by analyzing the relevant factors through experiment. This study used two factors 4×5 experimental design, one factor for screen lines, the other for pre-exposure time, to have 20 different experimental combinations. By processing the 20 experimental combinations randomly to have 45 samples each, there are 900 samples obtained finally. Through discussion and statistical analyzing, the study’s conclusions are as follow; 1. The photopolymer plate gets wide range of relief cell depths between 14 to 77μm in experiment, is suitable for most pad printing procedures in the market, 2. The relief depth of photopolymer plate have an inverse reaction with screen lines, also with pre-exposure time, it means the plate making operator can add the amount of screen lines and pre-exposure time to decrease the relief depths of photopolymer plate. 3. There are interactive reactions between two experimental factors for the relief depth control. As the increase of pre-exposure time, the effects of adding the amount of screen lines to reduce the relief depths of plate are diminishing, especially when adding the pre-exposure time to 6 or 8 seconds, the endeavors to decrease the plate depth have almost no effects; Moreover, as the increase of screen lines, the effects of adding the amount of pre-exposure time to reduce the relief depths of plate are also diminishing. en_US
