Printing Inks＇ Characteristics

Hybrid inks are often used for the advertising products because a variety of effects can serve as an added value. Much attention is paid to the inks application settings, using the hybrid inks at the hi-tech offset equipment and color features of images. The thorough research of the different printing settings with the use of modern inks and efficient equipment, is an urgent problem. Work reveals some new facts about characteristics for printability such as emulsification and influences of ink＇s additives on color characteristics of imprints. The experimental inks were developed to define the technological settings of offset printing. The result of research showed that conventional inks have the considerably high degree of emulsification comparing to experimental hybrid inks. Also it was discovered that the UV components influence the emulsification. An optimal water-ink balance and stable printing process can be achieved with adding of 2%-10% of the UV-component to the hybrid inks. Inks application and drying settings as well as color features of the imprints are analyzed in the context of offset printing.
