A STUDY OF THE PROCESS OF INK PENETRATION INTO PAPER BY ELECTRON MICROSCOPY
Published: 2 Jun 2014
Abstract: Results of study of paper surface microgeometry, "ink-paper" interface and ink distribution inside paper pores on base cross-section SEM-images and 3D-images, obtaining by laser scanning confocal microscope are demonstrated. EDS-spectrums and elements distribution of selected areas present in ink film and paper compositions with various surface microgeometry are shown. Quantitative evaluation of main parameters of surface microgeometry of different paper types was obtained. Various nature of ink film distribution at the "ink-paper" interface defined by surface microgeometry and paper structure is presented. The depth of ink penetration inside paper pores was defined. The ink penetration rate in view of surface profile parameters, depth of ink penetration, shape and pore size is calculated.
