Designing of Coating Color for Double Coating. Under-Coating and Printgloss of Double-coated Paper.

Under-coating and its effect on the printability of double-coated paper were studied. Five under-coated papers which were designed to have different coating structures were prepared and coated with same top-color. The printabilities such as inkset and printgloss of these double-coated papers were evaluated. The structures of under-coatings were analyzed and relation between the structure of under-coating and the printability of double-coated paper was discussed.
