Abstract: A study on artificial aging of stamp inks was presented. Inks for pre-filled stamps were artificially aged by UV lighting; the pigment and oil,the main components of inks,were analyzed by HPLC;and the change pattern of these components was obtained. Artificial aging caused remarkable changes of inks in a very short time.The peak area ratio between pigment and oil at different times was measured,and a curve revealing the relation between the ratio and time was drawn.The result could be used for reference in the examination of dating stamp inks.

Key words: HPLC, pre-filled stamp ink, artificial aging, UV
