A process for printing a coagulating ink composition directly on a substrate being supported by an adhesive surface, effected by cleaning the adhesive surface with a cleaning composition capable of removing residues of coagulated ink composition from the adhesive surface is provided, as well as a system for carrying out the process and a formulation for the cleaning composition. The cleaning composition comprises a weak organic base (preferably EDTA salts) and is characterized by a pH level of at least 7.5. |
