    Abstract : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. READ MORE

  2. 2. Where did the ink go? The effect of liquid absorption on ink distribution in flexography

    University dissertation from Karlstad : Karlstads universitet

    Author : Sofia Thorman; Karlstads universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexographic printing; print mottle; ink trapping; absorbency; absorption non-uniformity; water-interference mottle; Chemical Engineering; Kemiteknik;

    Abstract : The appearance of a print is affected by the individual ink layers. If the ink is unevenly distributed on the substrate it lowers the quality. This thesis puts focus on how the liquid absorbency of a coated substrate impacts on the ink distribution in flexographic printing. READ MORE
