N2 - During the printing process on liquid electrostatically printing (LEP), liquid ink is transferred from the ink tank to the media passing through a number of drums. First, the ink is transferred to the photoconductor drum, and then the inked image is transferred to the blanket drum by electrical forces, after drying the image on blanket drum it is transferred to the paper. Most of the printed images contain mid tone areas. These areas are composed of screened dots. When a dot is transferred from the photoconductor to the blanket, the dot is squeezed and as a result, the dot size increases. This phenomenon is called dot gain. The dot approximately expanded by 10% during the transfer between the photoconductor and blanket. In this work we present analytical model that simulate dot gain phenomena, a good agreement between analytical and experimental results are shown as well.
