Effect of ink and paper characteristics on optical properties of packaging papers.Part II:Viscosity of ink 50-55

Abstract

Effect of roughness & water absorption of paper and ink characteristics on optical properties was investigated. For this purpose three type of paper and four type of printing ink was used.Then characteristics of paper & ink was measured. Inks on sampled papers Printed and then L, a & b was measured. Result indicated that the effect of roughness and water absorption on L, a & b are not significant. But Solid content, PH and particles diameter of four type of ink on L, a & b have significant effect
