This research is concern with paper and ink interactions related to inkjet printing. The main purpose of this research is to a deeper understanding in which parameters control the flow of ink into papers and what will be the ink interaction with the paper surface here we have to find key parameters to optimize the print-quality in inkjet printing. The characterization of paper surface in term of porosity, surface roughness and surface energy. How the ink interaction with the paper light microscope imaging and SEM is used. A high speed camera is used to study the absorption of pricolitre sized inkjet droplet into fine papers. The research is done to see how surface fixation can affect the print quality for printout made with pigmented ink. The surface fixation increases the retention of the pigmented colorant in outermost surface layer of the paper. The applying colorant fixation onto a paper surface before printing can increase the detail reproduction in a printed image. In inkjet printing fat absorption of the carrier liquid into paper and fast fixation is necessary to avoid colour to colour bleeding. It is important to understand which papermeters affect the absorption process to control the mechanism and to optimized the print quality. A study of absorption of picolitre size inkjet droplets into fine paper was made in this research paper.
