Abstract

In this study, the dynamics of liquid capillary wicking (known as absorption, penetration, or imbibition) is discussed for a penetrant of an inkjet ink and commercial magenta inks. Different concentrations of penetrants on various printing media were tested, as well as magenta inks from HP and Canon. Penetrants are very efficient to wick inks on printing media and to reach maximum wicking area fast. The wicking areas of the penetrant solutions on test substrates are much lager than DI water. Since commercial ink contains 2 - 5% of penetrants, maximum areas of inks are larger than water and smaller than penetrant solutions. Alkylene glycol type penetrants such as Diethylene glycol monobutyl ether (DEGMBE), Diethylene glycol diethyl ether (DEGDEE) are to show large maximum wicking area and fast wicking rate. Alcohol type penetrants including Ethyl alcohol (EtOH) and Isopropyl alcohol (IPA) indicate fast drying rate at 100 and 50% concentration; however, drying rate of both alcohol type and alkylene glycol type penetrants at low concentrations are close to drying rate of water. Alkylene glycol type penetrants show less effects of concentration on wicking ratio, while concentrations of alcohol type penetrants greatly affects to absorption.
