Effect of Viscosity Reducer and Varnish on Ink-Transferring Ratio

Abstract:

In order to study influence of the variation of both viscosity and tack of the ink on the ink–transferring ratio. viscosity reducer and varnish to adjust ink viscosity and tack , the influence of the volume on tack volume and viscosity are obtained and also the influence of on the ink-transferring ratio by vatiation of the tack volume and viscosity . The results show that , the viscosity and tack of ink are both decrease with the amount of varnish and viscosity reducer increase. But varnish has a little effect on tack. Adding different proportion of varnish, ink-transferring ratio will reach best when the proportion of varnish is 2%. when addition more than 4%,the ink-transferring ratio will decrease instead. Adding different proportions of viscosity reducer, ink-transferring ratio will reach best when the proportion of viscosity reducer is 4%. When the amount of viscosity reducer more than 6%,the ink-transferring ratio will reduce instead.
