Abstract: A nondestructive discriminating system for writing inks was set up, which includes three approaches of microspectrophotometry, video spectral comparator and Fourier transform raman spectroscopy. 201 writing inks with different manufacturers, brands and models were collected from Chinese markets and divided into 7 groups, i.e. 35 black fountain pen inks, 20 blue-black fountain pen inks, 22 blue fountain pen inks, 49 black fluid pen inks (roller ball pen inks), 30 blue fluid pen inks, 45 black ball-point pen inks, and 50 blue ball-point pen inks. These inks were examined by the three approaches and the results showed that: 1. Inks in each group can be distinguished to a certain extent by each of the three approaches. The range of discriminating power is 50% to 94.4%; 2. Based on the results of the three approaches, the combined discriminating power for 7 groups is 93.4% for black fountain pen inks, 97.3% for blue-black fountain pen inks, 99.1% for blue fountain pen inks, 94.1% for black fluid pen inks, 97.2% for blue fluid pen inks, 95.6% for ball-point pen inks and 91.8% for blue ball-point pen inks, respectively. Obviously, the combined method has an excellent complementary effect and greatly raises the discriminating power. The nondestructive discriminating system offers an effective method to examine writing inks.

摘要： 本研究运用显微分光光度仪、文件检验仪和傅立叶变换拉曼光谱仪三种方法,分别对在中国市场上收集的不同厂家、牌号、型号的35种黑墨水、20种蓝黑墨水、22种蓝墨水、49种黑色墨水笔、30种蓝色墨水笔、45种黑色圆珠笔、和50种蓝色圆珠笔等七组样品进行非破坏检验。结果表明:(1三种非破坏检验方法都能单独对七组样品进行不同程度的鉴别,区分率在50%—94.4%之间;(2)三种方法联用后对黑墨水、蓝黑墨水、蓝墨水、黑色墨水笔、蓝色墨水笔、黑色圆珠笔和蓝色圆珠笔的区分率可分别提高到93.4%、97.3%、99.1%97.2%、97.2%、95.6%和91.8%。通过三种非破坏检验方法的联用,证明它们之间有较强的互补性,最大限度地提高了检验效应,可建立系统的非破坏检验方法。
