Printing with natural inks to the paper essential for various area like
wrapping paper for foodstuff, paper cups etc. Therefore, the development of
stable and commercial natural ink is gaining importance. The production methods
and the surfaces chemicals (coating materials, fluorochemicals, sizing
materials etc.) of the paper affect the color of the natural inks, which
applied paper surface. The aim of this study is to evaluate the effect of
natural inks on various paper types. Ink samples are cyan, magenta, yellow,
black colors prepared to have the closest color properties to the commercial
inkjet printing inks in the market. Yellow Curcuma
longa extract, red Rosa canina
extract, cyan Indigofera tinctoria
extract, black Alkanna tinctora
extract selected to prepare natural ink. The differences between the commercial
ink and the natural ink applied paper samples CIE L* a* b* color values were
evaluated. The application made with a commercial inkjet printer. Then strength
properties of paper samples evaluated and compared. According to results,
bleached white chemical paper color results were closest to commercial ink
