Influence of latex – oil interactions on offset ink setting and component distribution on coated paper
نویسندگان
چکیده
It is mainly the bulk properties of latex and ink oil that contribute to the observable differences in the ink setting dynamics rather than surface chemical wetting differences or changes in porous structure related to the inclusion of latex. It can be generalised that low latex solubility parameter (butadiene < styrene = acrylate < acrylonitrile) leads to greater oil interaction. Furthermore, latices with low Tg and gel-% show increased interactivity with ink oils. High oil solubility parameter, resulting from reactive groups in vegetable oils and aromaticity in mineral oils, causes greater latex affinity.

Distribution of Offset Ink Constituents in Paper Coating and Implications for Print Quality
The implications arising from the distribution of offset ink components in a paper coating structure are presented. The work focuses on two mechanisms causing differential distribution of ink constituents, namely (a) adsorption chromatography, resulting from coating pigment chemistry and morphology variables, and (b) latex-oil diffusional interaction. Adsorption chromatographic fractionation an...
