Printability of Ink for On-Demand Inkjet Printing on Different Paper

摘要

In order to evaluate the printing effect of self-made on-demand ink-jet printing ink and to study its influencing factors, its printing suitability and the influence of different substrate on its performance were studied in this paper. The drying process of ink on different paper was tested by contact angle tester. The color reproduction performance of self-made ink and common ink-jet ink was compared by measuring the printing samples of ink on different substrates with spectrodensitometer. The experimental results showed that the absorption rate of ink on offset paper was the fastest compared with that of coated paper and photo paper, and the drying time of self-made ink on substrate was shorter than that of ordinary ink-jet ink, which was basically volatilized and permeated in 2-3 s on offset paper. In terms of color reproduction performance, two kinds of three primary color inks could reproduce the better color of the image on the coated paper. The color strength of the self-made three primary color inks on the offset paper and the coated paper was higher than that of the ordinary ink-jet ink and the color hue error was smaller, so the color reproduction performances on the paper were better.
