Description
After introducing the topic in the previous episode and getting into the details of the problems that may arise before the inkjet application, this new episode focuses on the repellency phenomena that occur after the digital printing process at the interface between the solvent-based inks and the subsequent watery applications of glaze or grit suspensions.The different chemical nature of the inks (non polar polymers) and all the water-based suspensions (polar), is the basis of the critical issue and it basically results in a incompatibility between the two applications due to a lack of interaction. Just like between water and oil.The episode looks closer at the mechanisms behind the phenomenon, offering some effective actions to avoid or reduce it.
