Abstract

This work had an objective to study on lightfastness property of invisible UV fluorescent inkjet printing by comparison between two formulations of inkjet inks onto 2 different basis weight of plain papers using a desktop inkjet printer. The print was invisible under white light, but be visible under UVA/ blacklight. The fluorescent inkjet prints were studied their lightfastness property by exposing of blacklight for 248 hrs. The tested prints were evaluated ink fading. It was found that there was effect of ink fading on the different types of the printed papers which the heavier weight paper type had better lightfastness than that of the lower weight paper type. Furthermore, plastic film lamination on the print had capability to protect the printed from fading.
