The packaging industry is one of the pioneering industries facing many challenges during the production cycle. Migration of printing ink in packing items is the harmful problem for customer, Therefore, this study aims to reduce the penetration of ink into the product, one of the unavailable technologies is coating printing substrates with a polymer layer. Ecofriendly Super hydrophobic coating was prepared in aqueous medium based on silicon dioxide and characterized with particle size analyzer Dynamic laser scattering )DLS( and zeta potential. Paper duplex 180 g/m2 were coated with prepared superhydrophobic Nano coating through spray coating with emulsion solution. The coated paper sheets were printed by lithooffist and testes by X-rite instrument. This polymer can seal the pores of the printing materials. It is also a barrier to prevent the leakage and deportation of ink particles into the packaging that can occur in various raw materials, especially untreated materials as well as. One of the advantages of this polymer is to reduce the penetration of ink consumed for printing, that is, it is of double benefit, which is protection and reduce ink penetration, and the research results show the effective use of this polymer layer, whether in roughness, water absorption, Ink penetration and printing properties
