Abstract

A new generation of phase change, or hot melt ink will be formulated. This ink was solid at ambient temperature and liquid at the moment of printing. Inks will be formulated on the basis of polyethylene and Ethyl Vinylacetate chemistry. Inks were printed using a Meyer rod for screening printability study. Selection of the best formulations will be done on the basis of reflective density, specular gloss, mottle, and rub resistance. Screened inks having best properties were printed on the Moser laboratory sheetfed proofing press. More detailed printability analysis was done after Moser printing, including dot structure analysis, tone gradation, and mottling. The rheology of the best formulations was studied and compared to conventional rotogravure inks. Based on rheological measurements, additional changes on ink formulations were made.
