Abstract

The quality of ink-jet printing depends to a large extent on the technical characteristics of the selected equipment and the surface properties of the printed substrates. It is known that for digital printing it is necessary to use expensive paper with a special coating that determines the degree of gloss of the surface. Therefore, ordinary offset papers before ink-jet printing are covered with primers that ensure good fixation of pigment ink or dye on paper, a wide field of color coverage, characteristic gloss, which generally contribute to high quality of imprints. As you can see, the type of the substrate and the state of its surface has a very great influence on the quality of the imprints. Result of the research, it has been confirmed that not only expensive paper of a special purpose can be used for a drop ink-jet digital printing. High-quality color imprints can also be obtained on ordinary offset and coated paper, coated before printing with special primers based on interpolymeric complexes of polyvinyl alcohol, which will provide sufficient optical density, contrast of images, and expand the possibilities of digital ink-jet printing.
