article description
According to the previous study, the printability of electromechanical engraved cylinder and laser engraved cylinder were different in terms of density, tone reproduction and mottle. In this study, the missing dots of two different engraved cell types were investigated. It showed that different cell structures had strong effect to ink transferring and the characteristics of missing dots. Lasers engraved cells were less affected by ESA (electrostatic assist). When there was no ESA applied, the laser engraved cells showed less missing dot area, which indicated better ink release from spherical shaped cells. ESA had more effects to coated substrates than supercalendered substrates.
