紙張放久愈好用?
紙張中的纖維接受空氣中的溫度、濕度,會熱漲冷縮,放置長時間的紙,纖維會因這原理而彈性疲乏,此時會產生所謂“潤”的感覺,這種紙在使用時,纖維收縮膨脹會比較不明顯,所以存紙如存酒、存茶一樣愈久愈有味!
通常剛烘乾仍有熱度的紙,假設一百張是3000公克,等放置冷卻之後會變成3100公克,多出來的100公克就是水份,紙張既然愈放愈好用,就用塑膠袋存封放置,既可防潮又可防蟲,但此舉卻犯存紙之大忌,裝在塑膠袋中紙張內的水份,無法隨着空氣中的溫度、濕度吐納,黴菌在其中滋長,日久之後長了黃斑,我們說紙張長癌了,所以紙張的存放,不能照射光線,不能吹風,不能置於潮濕的地方,存放一段時間最好搬動整理,檢查是否有長蟲,是否有受潮,過濕冷的天氣最好用除濕機除濕。
